600V motors & drivers.

Omnidea had the need to develop its own high power density motors and drivers for the HAWE project:

150cc motor

Sensored with Hall sensors
Temperature sensor
Maximum RPM - 5000rpm
Kv - 8 RPM/V
Maximum power - 8kW
Weight 2.5kg

50cc motor

Sensored with Hall sensors
Temperature sensor
Maximum RPM - 5000rpm
Kv - 10 RPM/V
Maximum power - 3kW
Weight 1.2kg


Driver’s specs:

Maximum Voltage 800Vdc
Speed control with torque limitation
Voltage, current, velocity, motor temperature, driver temperature and torque measurements
CANbus specification 2.0 communication
Power side is optically isolated from the control side
IP67 enclosure with military standard connectors
Maximum power of 7kW
Weight 1.5kg

The drivers were built from scratch in house, the PCB was designed, built and all the components assembled and soldered by our engineers. The control uses a dsPIC33 that was implemented by Omnidea.
