CONTROLLERS

In the motion control industry, a controller is a device that drives motors; this enables precise control over a DC motor's performance characteristics like speed control, torque regulation, and positioning control. Brushless, brush, and stepper motor controllers will each operate differently due to the inner workings of the controller being dependent on the specific motor technology.

For example, BLDC motor controllers employ sensors to determine the position of the rotor and, with the help of transistors, change the current flowing through the windings. However, a stepper motor controller provides current in pulses; this energizes the stator’s poles and makes the rotor move.

Regardless of the motor technology, the choice of drive depends on the specific needs of the application in which the motor is being used. These consist of the desired speed range, torque control, and positional accuracy, as well as market-specific requirements like autoclavability. Portescap's autoclavable controllers can withstand up to 1,000 sterilization cycles, include both sensored and sensorless options, and are compatible with our BLDC slotted and slotless sterilizable motors.
