Closed Loop Stepper Motor Control System

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.

Closed loop stepper motor control system.

110vac kl 11008 hybrid servo driver closed loop control. 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. 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. Nema34 closed loop stepper motor system hybrid servo kit 32 bit dsp based 1128 oz in.

The system offers accurate and precise position control through feedback from the integrated encoder. The ac powered motor system can maintain higher torque during high speed drive compared to dc type motors and do not. 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.

The encoder is used as a feedback source in a position loop which adjusts the torque requirements in real time. The encoder feedback provides information of the current position of the motor in reference to the input pulse. Closed loop stepper motor system. 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.

Ai servo is a closed loop stepper motor system developed by autonics. The aica series ai servo motors are ac powered 2 phase closed loop stepper motor system featuring integrated drivers and controllers. For this reason closed loop controllers are also called feedback controllers. Closed loop stepper motor.

Closed loop stepper systems supply the motor with just enough current to control the load and this results in much less audible noise than open loop setups. Common names for this architecture include closed loop stepper control or servo.
