This year marks a significant milestone for Drive System Design (DSD) as we celebrate the 10th anniversary of our US business. A decade ago, we embarked on a journey to cultivate a community of exceptional engineers dedicated to inspiring and challenging the rapidly evolving mobility industry. 

Since our inception, DSD has experienced remarkable growth and success. Today, our teams in the US and UK comprise over 150 experts, united by a shared passion for engineering excellence and innovation. Together, we have forged a reputation for delivering cutting-edge solutions in electrified propulsion systems and associated technologies. 

As we reflect on the past decade, we are immensely grateful to our talented team whose dedication and expertise have been instrumental in shaping DSD into what it is today. Their commitment to excellence has propelled us forward, enabling us to establish ourselves as a trusted partner for automotive, off-highway, commercial vehicle, aerospace, and defence OEMs, Tier-1 suppliers, and industry research bodies worldwide. 

We pride ourselves on our turnkey capabilities and unmatched expertise and have built a team in the US that embodies that. We’ve grown to now be collaborating across a diverse array of sectors and become a trusted technical partner for many of our clients, without whom we wouldn’t be where we are today, and on the growth path we’re on for the future. 

As we commemorate this milestone, we extend a heartfelt thank you to our team, clients, and partners for their unwavering support and collaboration. After our acquisition by Hinduja Tech in 2022, our future holds even greater potential. Together, we look forward to the next decade and beyond, as we continue to drive innovation, shape the future of mobility, and redefine what’s possible in the world of engineering. 

Here’s to the next decade of excellence, achievement, and innovation at DSD! 

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.

Additional capability reflects industry trends towards increased electrification

Leading electrified powertrain engineering consultancy, Drive System Design (DSD), has announced a strategic expansion of its test facilities, adding two further test cells for high-performance hybrid axles and e-machines. The move reflects a growing demand for outsourced test capacity suitable for electrified powertrains, as the industry prioritises its development in response to global emissions concerns.

The first of the new facilities can deliver input torque up to 2,500Nm at 2,100rpm, 525kW at 7,000rpm, and 350kW 1,100V of battery emulation, with the second for e-machines up to 350kW and 25,000rpm. The new cells complement existing DSD facilities, which include a 450kW highly transient ETPS machine (Engine Torque Pulse Simulator) and three battery emulators.

“The recent Covid-19 pandemic has put an ever-bigger spotlight on our environment and recent government announcements on ICE restrictions is resulting in a faster shift to electrified vehicles than first anticipated,” explains David Kelly, Director, Drive System Design. “There is a significant increase in demand globally, not only for design and development work but also for outsourced testing. The additional facilities will extend our ability to provide this for a wide range of hybrid and electric powertrains.”

According to Kelly, even the largest, established vehicle manufacturers are struggling to accommodate the upsurge in test requirements using solely in-house facilities, and the situation is likely to become even more acute in future. “We are in the middle of a sea change in the industry, as the major players allocate more of their manufacturing to electrified vehicles,” he says. “Companies like DSD can provide vital additional resource to help satisfy short-term peaks in testing demand as this change in policy takes effect.”

DSD is continually developing its automation capabilities within the facility to help speed up testing. This has proven particularly effective in the case of hot and cold environment testing. According to Kelly, tests that previously took six weeks to complete can be finished in half the time with suitably configured automatic control.

DSD intends to have the new test cells operational in December this year.
