AlphaStep

Closed Loop Step Motor & Driver Systems

Sensor

AlphaStep is Oriental Motor's original closed loop control technology which maintains positioning operation even during abrupt load fluctuations and accelerations. The rotor position detection sensor monitors the rotation. When an overload condition is detected, the AR Series will instantaneously regain control using the closed loop mode. When an overload condition continues the AR Series will output an alarm signal, thereby providing reliability equal to that of a servo motor.

Closed Loop Control

AlphaStep maintains positioning operation even when subjected to abrupt load fluctuation or acceleration. The newly developed rotor position detection sensor constantly monitors the motor movement. If synchronism is about to be lost, closed loop control is used, eliminating concern for loss of steps. .

No Hunting

Since AlphaStep is a stepping motor, it has no hunting problem. Therefore, when it stops, its position is completely stable and does not fluctuate. AlphaStep is ideal for applications in which vibration would be a problem.

No hunting

High Response

Like conventional stepping motors, AlphaStep operates in synchronism with command pulses. This makes short stroke positioning possible in a short amount of time.

High Response

A Single Driver to Support a Variety of Motors

Various types of motors, such as the standard type and the geared type, can be attached to a single driver. Therefore, there is no need to change the driver to match the motor to be attached. Maintenance is easier.

A Single Driver to Support a Variety of Motors

Actuators are also available.

No Gain Tuning

Gain tuning for servo motors is critical, troublesome and time-consuming. Since AlphaStep operates like a stepping motor, there are no gain tuning requirements. Low rigidity applications, such as a belt and pulley system, are ideal for AlphaStep.
