A high-power versatile motor controller, 3-phase DC to AC inverter platform equipped with current sensors, drivers, and DC link capacitors. The system is optimized for the electrification of commercial drive trains.

The SKAI 45 system contains an integrated controller, compatible with hybrid and battery-powered vehicles. Designed to operate with battery voltages from 24v-800v, output power ratings 10-250kVA.

The motor control software, QUASAR is based on a field-orientated closed-loop control system. QUASER receives input commands from a central controller via CAN bus and converts this precisely into speed or torque for the control of the motor – systems available with or without software.

The system is enclosed in an IP67 rated enclosure together with all the power terminals for motor and battery connection as well as signal interfaces for CAN communication, analogue and digital I/Os and auxiliary power supply.

Motor temperature sensors and sensors for angular and motor speed feedback (encoder, resolver) can be directly interfaced to the SKAI.
Suitable environmental conditions in accordance with ISO 16750-(B,F)-N-K-D-Z-IP(6K7;6K9K).
