Closed Loop Stepper Motor Control System

Closed loop stepper motor.

Closed loop stepper motor control system.

The encoder feedback provides information of the current position of the motor in reference to the input pulse. The definition of a closed loop control system according to the british standard. A closed loop controller therefore has a feedback loop which ensures the controller exerts a control action to give a process output the same as the reference input or set point. The system offers accurate and precise position control through feedback from the integrated encoder.

The aica series ai servo motors are ac powered 2 phase closed loop stepper motor system featuring integrated drivers and controllers. To produce the test results shown in the plot of acoustic noise accompanying this article the acoustic noise of each system is measured in a soundproof chamber. The encoder is used as a feedback source in a position loop which adjusts the torque requirements in real time. Alphastep products are stepper motor based hybrid motors with a unique hybrid control system combining the benefits of open loop control and closed loop control.

The position of the motor is always monitored and then the driver automatically switches between 2 types of control depending on the situation. The motor system can control motion of multiple axes directly with network communication.

Stepper motor systems using closed loop control represent a small percentage of stepper motor applications but if loss of position could be catastrophic to the application yet the system requires high torque at low speed relatively simple architecture and relatively low cost compared to a true servo motor system a closed loop stepper might be the most appropriate solution. Ai servo is a closed loop stepper motor system developed by autonics.

For this reason closed loop controllers are also called feedback controllers. Common names for this architecture include closed loop stepper control or servo.
