Drivers and controllers for DC brushless motors with Hall sensors

DC brushless motor controller

We offer BLD and BLSD controllers for DC brushless motors with Hall sensors.

BLD drivers control speed, direction, smooth start and stop of brushless motors according external signals to special inputs.

BLSD controllers operate with brushless motors with current up to 50 A. These controllers adjust speed, direction, smooth start and stop of brushless motors both per internal signals and per commands via RS‑485.

The latest model is BLD-2 mini - it is a DC brushless driver integrated with a motor.

Speed control - BLD and BLSD series controllers provide analog speed control according voltage input signal 0 ‑ 5 VDC or according internal potentiometer position. Usage of external potentiometer for speed control is also possible.

Acceleration/deceleration - smooth start and stop are ajusted by internal potentiometer "acceleration" (except BLD ‑ 2 mini, which provides smooth start and stop but doesn't have such potentiometers).

Reverse - reverse input by default is pulse logic - the motor changes rotation direction as per the front edge of signal at "reverse" input (clean contact). At client's request the input logic can be changed to level logic - the low level at the input correcponds to one direction, high level - to reverse direction. Open collector for PLC connection is also possible. The reverse input is also dublicated as a button on the controller's case.

Start/stop - start/stop input is intended for motor rotation start and stop (except BLD ‑ 2 mini). By default this input is pulse logic - the motor start or stop as per the front edge of signal at "start/stop" input (clean contact). At client's request the input logic can be changed to level logic. Open collector for PLC connection is also possible. The start/stop input is also dublicated as a button on the controllr's case.

RS‑485 - the communication input at BLSD series only - it is intended for command control via RS‑485 intarface. All motion commands (start, stop, acceleration, deceleration, speed, conroller's network address) are sent to the controller as 5-bytes messages. This control mode provides information about real motor speed, direction, counter state (counter of complete motor revolutions). Pulse quantity per motor revolution is set by special command. So different poles motors can be used with the controller.
