αSTEP Hybrid Control System

Closed Loop Stepper Motor Systems

Oriental Motor’s αSTEP closed loop stepper motor control systems perform accurate positioning operations with ease. The αSTEP features a unique control system combining the benefits of “open loop control” and “closed loop control”.

With the αSTEP stepper motor control system, the position of the motor is always monitored and then the driver automatically switches between the two types of control depending on the situation. Under normal circumstances the operation of the motor is monitored and control is applied using open loop like a standard stepper motor. If an error occurs between the command and motor position due to a load or the like, the system immediately switches to closed loop control like a servo motor. This corrects the position and speed maintaining the desired operation. The combination of these two control methods ensures high reliability and performance.

To expand applications of stepper motors, Oriental Motor offers many different product series designed with different power specifications and various functions. A wide spectrum of variation are available within each series, as products come in many frame sizes and pre-assembled options, such as electromagnetic brake types, geared types or linear and rotary actuator products.
