UK motor controller specialist Sevcon has expanded its range of advanced technology Gen4 motor controllers for electric vehicles with the introduction of a new high power unit. The latest addition to the Gen4 range, the Size 8 AC motor controller, is designed to meet the high performance and safety requirements of on-road and off-road electric vehicles and hybrid electric vehicles.

The hardware platform of the new controller supports both AC induction and permanent magnet AC motor control technologies. The new controller has a continuous power output of up to 60 kW‚ with a peak output of up to 100 kW‚ and is capable of running from a peak DC supply voltage up to 400V.
Advanced flux vector control improves traction control efficiency and motor responsiveness, channelling drive power and energy from the battery smoothly and efficiently. In addition‚ the controller is designed to support a wide range of vehicle functional safety requirements including ISO 26262.
Multiple motor sensor feedback options are provided through a range of hardware inputs and software control. Fully integrated sets of input and outputs are designed to handle a wide range of vehicle functions, eliminating the need for additional external input/output modules or vehicle controllers and connectors.
Alternatively, for a lower level of vehicle integration‚ the controller can operate as a motor slave, directly receiving a required motor torque/speed command via the CANbus. The CANopen bus also allows the easy interconnection of multiple controllers and motors as well as devices such as displays and driver controls.
In February, Sevcon announced it is providing compact, high power controllers for Peugeot’s new e-Vivacity battery-electric scooter designed for urban use. (Earlier post.)
