Brushless motor controllers are bi-directional and used to control the velocity and / or the speed of a brushless motor. Controlling the speed can be as using the on-board potentiometer or hooking up an external speed control like a potentiometer, PC or PLC. Other features include minimum and maximum speed settings, acceleration and deceleration adjustments, electronic braking, and a 12 pulse per revolution output to monitor the speed. Brushless DC motor controllers can provide up to 10 amps of continuous power. For smaller motors, a jumper is installed for selectable 12 or 24 volt operation. Brushless DC motor controllers are low cost, easy to use solutions for speed and position control.
