Closed Loop Stepper Motor Control System
Ai servo is a closed loop stepper motor system developed by autonics.
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. The motor system can control motion of multiple axes directly with network communication. The definition of a closed loop control system according to the british standard. The system offers accurate and precise position control through feedback from the integrated encoder.
The encoder feedback provides information of the current position of the motor in reference to the input pulse. 110vac kl 11008 hybrid servo driver closed loop control. Common names for this architecture include closed loop stepper control or servo. Closed loop stepper motor.
For this reason closed loop controllers are also called feedback controllers. The aica series ai servo motors are ac powered 2 phase closed loop stepper motor system featuring integrated drivers and controllers. The encoder is also being used in a current loop to determine the proper electrical angle to apply to the 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.
Closed loop stepper motor system. The position of the motor is always monitored and then the driver automatically switches between 2 types of control depending on the situation. The encoder is used as a feedback source in a position loop which adjusts the torque requirements in real time. 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.
