G03 supports both 340Vdc and 540Vdc voltage platform and its max. output current can reach up to 410Arms and 525Arms accordingly. G03 has been applied to all kinds of trucks, 8-10m buses, logistics vehicles and compatible with synchronous and asynchronous motor.
Different filtering tactics in ACR make the output torque smoother with quick response, improving the comfortability for driver and passengers dramatically.
Big power density, compact size and light weight. On the premise of ensuring the power, this can effectively reduce the weight of vehicle body.
Quick torque respond time: <5ms; Torque control accuracy: ±5%.EV/HEV traction motor controller-G03 frame
