Stepping motors are highly precise, digitally controlled motors that are able to provide reliable operation without using detectors to sense or indicate position. The operation of the motor is controlled through electrical pulses. The direction of current flowing through the windings of the motor is switched with each pulse. The electrical pulse is converted into shaft rotation in steps of a fixed angle. Together with the driver, it constitutes an open loop controlling system, which is of low cost and simple to construct.

Precise Position Control The specified number of pulses determines the output degree(s) generated. |
