Comau's electric drive production line, commissioned in 2023 for a Chinese automotive manufacturer, was designed for a planned annual capacity of one million electric drive systems. The line has now received the Best Technical Practice Application Award at the 8th Gasgoo Golden Gear Awards, held in Shanghai. Wallace Bie, Head of Marketing APAC at Comau, accepted the award on the company's behalf.
The customer is not named. The award covers the line as a whole, which Comau developed for next-generation electric drive systems, known as EDS.
What the line covers
The line was delivered and commissioned in 2023. It spans several of the main manufacturing stages for an electric drive system: motor assembly, gearbox manufacturing and assembly, inverter assembly, and end-of-line testing.
Putting these stages in one production system means the motor, gearbox and inverter are built and checked within a single manufacturing arrangement. The line is designed to run at the planned capacity of one million units a year. The award announcement does not say how many units the line has built or at what rate.
Comau says the line has continued to support high-volume manufacturing since it entered production. No output figures, uptime numbers or cycle times accompany that statement.
How one line handles two motor types
The central engineering feature is mixed-model production. The line builds both induction motors and permanent magnet motors, which allows different electric drive configurations to share one manufacturing system.
The two motor technologies differ in their assembly processes and cycle times. Comau and the customer worked together on an adapter system fitted with a zero-point positioner to deal with those differences. The adapter allows quick changeovers at the tooling level. As a result, the production line itself needs fewer complex adjustments when the product changes, and it can accommodate a wider range of product configurations.
Several other technologies are built into the line. Robots guided by quadocular stereovision 3D vision handle automated assembly work. AGVs supply material autonomously, and automatic tool-end loading supports material handling. The announcement does not give the number of robots or vehicles, or where each one sits in the process.
The award and its criteria
Gasgoo organizes the Golden Gear Awards to recognize innovative technologies and outstanding practices across the automotive value chain. This year's Best Technical Practice Application Award carried the theme "Chinese Solutions for Global Markets."
The award looks at four things: technological innovation, engineering maturity, real-world application, and the potential to scale solutions across different applications. It is aimed at manufacturing technologies that have been implemented in industrial settings, and at their practical effect on automotive production.
Comau says the recognition applies to the project's engineering achievements in mixed-model production across different motor technologies. The company also presents it as evidence of its automation engineering and system implementation capabilities for electric drive manufacturing for new energy vehicles.
What the award does and does not show
The most useful detail in this story is the changeover approach. Electric drive makers face a practical problem: induction and permanent magnet motors are different products with different assembly needs, and demand for each can shift. A line that handles both through a tooling-level adapter, rather than through reconfiguration of the line, addresses that problem at the point where it usually costs time. The zero-point positioner is a way of fixing the tooling reference so that swapping the adapter does not require re-establishing the setup each time. That is a reasoned reading of the design, not a measured result.
The timing is also informative. The line was commissioned in 2023 and is being recognized in late 2026. An award given after several years in production carries more weight on engineering maturity than one given at launch, because the criteria include real-world application. The line has had time to run. Even so, the announcement offers no performance data, so the claim of sustained high-volume output rests on Comau's statement alone.
Several points remain unproven in public. The changeover time between motor types is not stated. Neither is the proportion of induction to permanent magnet motors the line actually builds, or whether the full one million unit capacity has been reached. The planned capacity is a design target, not a reported result. The customer's identity is also withheld, so the claims cannot be checked against the manufacturer's own figures.
The scalability criterion deserves caution as well. The award considers the potential to scale solutions across applications, but the announcement describes one line for one customer. Whether the adapter and positioner approach transfers to other motor designs, other plants or other customers is not shown. The two motor types in this project are a specific pairing, and other drive configurations may need different tooling logic.
For the wider field, the project points to where electric drive automation is heading: integrated lines that combine motor, gearbox, inverter and test, with vision-guided robots and autonomous material supply inside the same system, and flexibility built into the tooling. Whether that design outperforms separate dedicated lines for each motor type cannot be judged from this announcement. That comparison would need changeover times, utilization and yield figures from the line, and the customer would have to release them.
