BLDC Sensorless

Servo drive for brushless motors without hall sensors up to 1kW (3.3Nm), power supply up to 95Vdc, currents up to 10 / 20A

Bldc Sensorless© is a digital drive for brushless motors up to 1KW 3.3Nm. The board is equipped with 5 power terminals (2 power supply + DC and -DC and the three outputs to the motor U, V, W). Thanks to the technology adopted, the Bldc Sensorless© drives do not need the connections coming from the hall cells of the motor. Power supply from 20 to 95 Vdc. Currents up to 10A rated / 20A peak. Typical application: Submersible pumps with brushless motors.

Available functions:

  • Analog speed input
  • RS232 interface, Mod Bus-RTU protocol
  • Feedback: not necessary
  • 3 wires only motor connection: U, V, W
