Vehicle Motor Controllers

An AC motor controller (inverter) converts DC battery power or generator power in a hybrid vehicle, into three phase rotating AC current suitable for efficiently powering an AC motor. Kollmorgen vehicle motor controllers are capable of powering asynchronous induction AC motors as well as synchronous PMAC motors, brushless DC motors and synchronous reluctance motors.

Kollmorgen is the leading global supplier of AC vehicle motor controllers suitable for integration in a wide variety of battery and hybrid vehicles. With a rugged design suitable for the demanding environment in a vehicle, Kollmorgen motor controllers achieve industry leading quality and reliability through superior design and manufacturing processes. Software quality is ensured by utilizing design processes designed to measure up to the demanding Automotive-SPICE™.

With an ample selection of voltages, power levels, I/O and feature sets, Kollmorgen’s vehicle motor controllers are well matched against the vehicle manufacturer’s need for traction, hydraulic, and steering control in an electric vehicle design. Kollmorgen’s extensive experience of integration into both industrial vehicles such as forklift trucks or golf carts, as well as on-road vehicles such as buses or refuse trucks has resulted in a unified controls platform. The features and functionality of the platform is shared across the entire Kollmorgen vehicle motor controller line-up.

The Kollmorgen controllers allow the vehicle motors to always operate at their optimal efficiency for a given speed/torque point by utilizing state of the art flux vector control. Additionally, the controller firmware supports many of the commonly desired features in an electric vehicle, such as configurable regenerative braking behavior, hill-hold, Best Performance Curve, etc. The common PLASMA software platform has support for the commonly used J1939 and CANopen communication protocols and furthermore allows extensive functional customization for optimal integration into a vehicle.
