Expanding our Electrified Propulsion offering is a significant step in our ability to deliver fully integrated systems to our customers throughout the world.”

Lee Rogers, Principal Engineer – Electrified Propulsion, at Drive System Design (DSD), outlines how powder metal gears can support EV production and how DSD’s work with industry-leading materials specialist Alvier has supported the development.

Manufacturers throughout the transport industry are aware that they now need to be placing significant investment in cheaper, cleaner, lower carbon technologies to support net-zero goals.

When considering our customers in the European Union (EU) in particular, we know that increasing legislation around lower carbon footprints is placing even more pressure on them to find sustainable electrification solutions.

What are we doing?

In collaboration with Alvier, specialists in advanced materials and production methods for sustainable high-volume applications, we are integrating powder metal gears into an automotive EDU demonstrator. This near-net-shape design eliminates a significant amount of material waste with a minimal difference in package/weight when compared to traditional forged gears.

These gears can be used in a range of vehicle sectors from automotive to off-highway and will enable significant cost savings at high enough volumes. The major reduction in CO₂ is also a major bonus as Electric Vehicle (EV) production volumes rapidly increase.

We’re not stopping there. We’re supporting our customers by providing guidance on how to implement the gears into their specific systems, to ensure their needs are met whether they’re manufacturing cars, trucks or tractors.

How did we do it?

Our partnership with Alvier enabled us to replace some traditionally manufactured gears in an EDU with a powder metal counterpart.

• Identifying the right candidate

Utilising Alvier’s experience in powder metallurgy, which is the process used to develop powder metal gears, we built an understanding of the manufacturing constraints that would apply in volume production. When combined with DSD’s transmission engineering expertise we were able to identify the right component candidates to be replaced with powder metal gears. This led to us identifying the gear wheels as good candidates.

• Understanding the material performance

The next step was to understand the differences in material properties. The strength and noise performance of the gears must be equal to or better than a traditional solution to be competitive. DSD performed modal characterisation of both forged and powder metal gears to understand their baseline differences in terms of frequency and damping.

Similarly, using Alvier’s understanding of the powder metal fatigue performance, DSD was able to size the gears to meet the required contact and bending safety factors.

• Predicting performance

Using the characterised material data we were able to simulate the NVH and strength performance of the gear design against the original requirements. We predicted that these would have similar performance to the existing forged gear wheels. This meant me were able to move onto the prototype stage with confidence that the gears would work successfully.

• Finding the break-even point

Before entering the production phase, we used our ePOP tool and costing experience to model the breakeven point of the powder metal gears against the existing forged gears, to understand what volumes would be economically successful.

What’s the result?

The collaborative effort with Alvier throughout the process means we now have the confidence to take this powder metal gear design into prototype hardware. The thorough understanding of the manufacturing constraints, material properties and resulting performance means DSD is primed to help OEMs and Tier suppliers integrate this new technology into their products successfully.

Why DSD?

Successfully integrating new technologies such as powder metal gears to achieve lower cost and carbon footprint requires a collaborative approach that involves both manufacturing and design expertise.

High-frequency abnormal noises continue to pose challenges to engineers when developing electric and hybrid vehicles.

It’s truly an exciting and highly opportunistic time for engineers, as we build out an entirely new energy ecosystem on a global scale, full of uncharted territory and exhilarating challenges.

While much of the obvious focus is on what will be made, the engineering community is focused on how it will be made. The mix of traditional engineering and software integration has caused nearly every manufacturer in the EV space to rethink how to build their development teams to get their products to market quickly, reliably and cost effectively.

At the recent SAE COMVEC™ a panel about the “war for talent” struck a chord with our team about the challenges we face, where we find ourselves and where we’re going as engineers. With an estimated $1.2 trillion being invested in EV development through 2030, the type of engineering necessary to build not only the vehicles themselves, but the technology and infrastructure to support them is requiring an entirely new type of thinking and collaboration – along with a significant amount of hiring. As we continue to see investments taking place in our backyard, such as CNH Industrial recently announcing that it has opened a new technical centre in metro Detroit to support its growing innovations in electrification, the competition for talent locally surges.

DSD has a strong history of developing powertrain technology and collaborating with OEM partners to supplement and reinforce their internal teams. Our expertise lies in having experienced and forward-thinking engineers who go into a project with an open mind to find the right solution for a specific application. With years of expertise in the segment, our company has continued to evolve our EV propulsion capabilities and excels at developing motors and controls for the automotive, aviation, commercial vehicle, off-highway and defence industries.

The COMVEC panel drew attention to the obvious need for expanding engineering talent, training and hiring, but also of having partners in place to supplement manufacturers where needed.

Further, a recent Automotive News storey cited the 35% increase in STEM-related jobs during the past 20 years, which is expected to increase even further during the next decade. The pressing question is whether there will be enough incoming talent to meet the demands of the industry. There are programmes locally in place to help kerb the issue, for example, the Detroit Regional Chamber Foundation and MICHauto recently were awarded a $2 million grant to support the growth and development of high-tech talent in Michigan, spanning automotive, mobility and technology sectors, but some of these measures will take a significant amount of time.

With the substantial investment in the move to EVs, our customers must determine if they should build or expand their internal product development teams, work with trusted partners or both. It’s an interesting position for companies like DSD. The company can be hired to supplement internal programmes or be contracted for turnkey development.

DSD routinely supports clients with our trusted engineering team members – having them work on-site with the customer team. This can be extremely beneficial when projects come in and there just isn’t time to find the perfect candidate for the job. And since there are more opportunities than there are engineers suited for positions, finding the right hire and having them commit can take time – something that manufacturers don’t always have.

Of course, a key concern with outsourcing projects through contractors can be that once the project is over, the knowledge behind that project goes with it. In an effort to collaborate at the deepest level and facilitate the creation of rapid and effective teams, our clients take the IP with them upon a project’s completion.

DSD’s advantage lies in the fact that we understand what our customers need and fully realise that what they need today, may change drastically in 12 months. Further, the company has the flexibility, capability, and expertise to work in multiple segments and on multiple projects across multiple regions at the same time. This allows us to pivot easily and ramp teams up or down to align with client needs.

We understand the difficulties of deciding whether or not to staff up or collaborate with companies like DSD to supplement an existing workforce, and we are prepared to help our customers navigate that decision, helping them minimise the risk and maximise the ROI.

Drive System Design (DSD), a company specialising in the rapid engineering and development of electrified propulsion systems and associated technologies, has developed a new method and strategic plan to better support clients in designing and developing electric motors and inverters that best fit their needs.

DSD has observed that many motor and inverter manufacturers, as well as system integrators, often take their electrification development programmes directly to a dynamometer (dyno) test cell, only to uncover critical issues that need to be overcome, which can stop the programme in its tracks. With this seemingly direct approach, months are added to the project timelines in order to find and fix unforeseen integration issues.

To help save its customers months of time and tens of thousands of dollars, while ensuring a more robust, reliable concept before ever touching a dyno test cell, DSD has created a new Motor Control Development Method consisting of four key phases that it will now implement for most electric motor and inverter development projects.

“There is immense benefit in minimising project risk by following our four-phase approach. Too often, a push to be first-to-market ends up incurring more cost and time,” said Jon Brentnall, president, Drive System Design. “Ultimately, this approach will enable our customers to be first-time capable, meaning they will be set up for a successful pairing of the inverter and motor once the product reaches the dyno test cell. This will speed up final validation and significantly reduce the risk of needing extra hardware iterations, saving our customers both time and money while delivering a more high-quality product.”

Below is a look at DSD’s four-phase approach, with many companies currently skipping from Phase 1 to Phase 4:

• Phase 1 – Concept evaluation and design with advanced co-simulation. During this phase, control algorithms, finite element analysis (FEA) motor models and the power electronics model are designed and developed. A closed loop advanced co-simulation of the entire system will then be performed. By driving the system model with more representative control signals rather than simpler idealised inputs, early-stage identification of electromagnetic challenges along with accurate early-stage data for larger system analysis activities like noise, vibration and harshness (NVH), can be achieved.
• Phase 2 – Detailed design and validation with Control Hardware-in-the-Loop (C-HIL). DSD will utilise inverter control board hardware with deployed software and a real-time simulation of the motor model. The C-HIL hardware emulates motor behaviour and sensor feedback such that a large proportion of the software and low voltage hardware validation can be performed. This phase allows for development and validation of safety monitoring and fault handling without risking hardware failures. Software development time is reduced for subsequent phases through bug fixing at this stage.
• Phase 3 – Component level testing with Power Hardware-in-the-Loop (P-HIL). At this stage, a large proportion of the inverter validation will take place by running full power through the inverter with deployed software and utilising a battery and a high voltage motor emulator. The motor is modelled but real current and power is being pushed through real inverter hardware to validate its power stage and control. When a novel motor design is in the manufacturing stage, DSD can leverage its open platform inverter, to quickly and efficiently develop, calibrate and validate the motor controls for that application in this phase of testing.
• Phase 4 – System level testing and validation on a dyno test cell. The motor will enter the dyno test cell at this stage as a final system validation and characterisation utilising inverter and motor hardware as well as the battery emulator. Going through the previous stages ensures this phase will be as short, cost effective and efficient as possible.

As an initial investment to fulfil its new motor development strategy, DSD has acquired a C-HIL rig, which will be housed at its technical centre in Farmington Hills, Michigan. Additionally, DSD will be partnering with the Auburn Hills-based rig supplier to have access to their P-HIL rig and motor emulator, with plans to invest in one of its own next year.

“Real-world issues can now be predicted or reproduced and solved prior to – or in parallel with – dyno or test cell work,” said Brentnall. “This new approach and equipment will further advance DSD’s turnkey capability of delivering motor controls and electrification across a range of markets.”

Through DSD’s method, customers will now be able to better optimise their time, as a large proportion of the inverter software and hardware can be developed and validated through Phase 2 and 3 while the motor hardware is being made. Further, the method is adaptable for various vehicle types, including automotive, trucking, off-highway, defence and aerospace.

With the immense value of taking a more comprehensive approach to motor and inverter design and development like DSD’s, the company predicts that most companies tackling similar projects, including key competitors, will adopt a similar approach in the next five to 10 years.
