Electromen - EM-151B BLDC motor 4Q drive 12-24 V dc, 20 A
EM-151B is a DC-motor driver for brushless dc-motor with hall-sensors. The commutation angle can be 60 or 120 deg.
It has two modes for speed control. In open loop mode driver works like normal dc-motor speed controller. In closed loop
mode the hall pulses are used as speed feedback. Closed loop mode offers a high accuracy in speed control.
The speed control input signal can be scaled with zero and range trims. Card includes also an acceleration and deceleration ramp adjustment for smooth starts and stops. The ramp is used also in direction change, that way it can be done controlled and smoothly. Current limit is also adjustable with trimmer. Regenerative braking can be used when power is supplied from a battery. In this case the current limit adjustment works also in braking. In overcurrent the driver activates the fault output.
