HV IGBT speed controllers

High voltage speed controllers for high performance electric motors (80kW, 400V) are ideally suited for use in electric cars, aircraft, UAVs, industrial applications, and more.

These controllers are also at home in electric motorbikes, ships, boats and other electric vehicles. They can also be found in oil pumps, winches and cranes, robots and a full range of other industrial applications.

Rated performance up to 80kW (400A, 400V)

These industrial speed controllers apply the most advanced IGBT modules in order to achieve maximum efficiency (98% - 99%). They are an intelligent solution with high-performance 32-bit ARM Cortex processors used for control. Advanced algorithms are used to control the motor and secure safe operations. The design is based on a many years of experience with BLDC (or PMSM), both with and without Hall sensors, in extreme duty applications and very difficult operating conditions. Impressive performance, small dimensions and low weight are characteristic. These speed controllers also offer a range of innovative functions, control and configuration options and PC communication capabilities. Real-time monitoring and logging of operating data are givens. Excellent motor control is complimented by unique battery management and protection. Active safety components, expanded to include the Emergency Stop function, make operation even safer. This is a completely unique feature and particularly invaluable for electric vehicles, allowing traction batteries to be disconnected when the motor is running. Hardware and software customization is possible using customer specifications and needs to transform these speed controllers into extremely efficient components for a wide spectrum of uses. Firmware and software updates available on the internet are a given for all MGM COMPRO controllers. The latest information and expertise are always and conveniently available to our customers online.
