AC Motor Controller Dragon 8

borgwarner ac motor controller

AC Motor Controller Gen4 Size 8

The Dragon8 sets a new standard in AC motor controller performance and reliability. It is compatible with a wide range of motors – Asynchronous AC Induction and Synchronous
Permanent Magnet AC (PMAC) or Brushless DC (BLDC).
Dragon8 has electrical isolation between high power battery/ motor wiring and the lower voltage control signals and CANBus.

This allows the IO to reference the 12 V (or 24 V) battery and vehicle chassis return path.
