Many automakers design and build their own electric motors for their electric vehicles. Meanwhile, others source their motors from suppliers.
Whether to build or buy engines depends on several factors, including cost, supply chain considerations, and engineering expertise.
According to EV Central, many brands do not usually buy motors from big automotive component suppliers like Bosch and Infinitum.
Some, such as BMW, design and manufacture their engine, while others collaborate with partners.
Meanwhile, Yasa, in partnership with Mercedes Benz, is leading the way into the EV motor evolution with their Axial Flux Technology.
Moreover, GetJerry noted that General Motors has recently unveiled plans for a new electric motor facility, which may eventually allow GM to sell its motors to companies like Tesla.
GetJerry further stated that this new plant would reportedly consist few main focuses, including the production of:
● Three new electric motors, known as the Ultium lineup.
● The Hummer EV, along with more electric vehicles in the future, will utilize these electric motors.
● New engines are as much as 50% smaller in volume and 25% more potent than current EV engines.
“GM will soon make EV motor parts in western New York. The automaker announced a $154 million investment in the Lockport Components plant, bringing EV motor stators to the plant’s production lines. The stator is a stationary part within the motor’s rotary system. It creates a magnetic field to help drive the rotating armature. Essentially, it’s a crucial component for any electric motor.”

On the other hand, some EV motor manufacturers have provided by Rx Mechanic:
● Siemens
● Toshiba
● ABB
● Nidec Motor
● Rockwell Automation
● Ametek
● Regal Beloit
● Johnson Electric
Whether to build or buy electric motors is complex, and each automaker must weigh the benefits and drawbacks of each approach. Building electric motors, in-house can give automakers more control over the design and performance of the engines. Still, it can also be more expensive and require higher expertise.

Sourcing motors from suppliers can be more cost-effective and efficient. Still, it can also limit the automaker’s ability to customize the engines to their specific needs.
