Drivers and controllers for DC brush motors

We offer BMD, BMD-R and BMSD controllers for DC brush motors with rated current up to 20A and voltage below 48VDC. BMD drivers control speed, direction, smooth start and stop of DC brush motors according internal signals to special inputs. BMSD controllers adjust speed, direction, smooth start and stop of DC`brush motors both per internal signals and per commands via RS485. Another function of BMSD controllers - speed stabilization for motors with encoder.

BMD-R is the controller similar to BMD unit, but with remote control option. It is used with motors current up to 12A.

Speed control - BMD, BMD-R and BMSD controllers provide analog speed control according voltage input signal 0-5VDC 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".

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) or according level logic - the low level at the input corresponds to one direction, high level - to reverse direction. Please, specify the logic befor ordering. 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. 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)or according level logic - the low level at the input corresponds to motion, high level - to motor stop. Please, specify the logic befor ordering. level logic. Open collector for PLC connection is also possible. The start/stop input is also dublicated as a button on the controller's case.

RS-485 - the communication input at BMSD controller - 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 (for motors with encoder), direction, counter state (counter of complete motor revolutions, for motors with encoder).
