YASA, a manufacturer of axial-flux electric motors, announced availability of the first in a new series of motor controllers (inverters) for propulsion and generation applications in pure electric and hybrid vehicles.

The new Si400 controller delivers 200 kVA (400 V and 500 Arms) from a 5-L package weighing 5.75 kg. The controller features thermal management including dielectric oil cooling and is suitable for use with induction, permanent magnet, and axial-flux electric motors. The company says that when coupled with its axial-flux electric motors, the Si400 controller offers high efficiency and control dynamics.

Si400 samples are available to OEM and tier-one customers.

Speaking of the launch, YASA CEO Chris Harris said, “With this new series of controllers, we’re responding to our customers’ demand for increased flexibility in powertrain design. The first release in the series, the Si400, is significantly smaller and lighter than competitive products and when coupled with our axial-flux motors enables significant improvements in vehicle performance, range, and cost. This will mean greater choice for consumers, increasing the already rapid adoption of electric vehicles and setting the bar for driving experiences.”
