Stögra - Encoder for Stögra Stepper Motor
In non disturbed operation the stepping motor runs synchronously to the pulses coming from
the control. That means the motor rotation (= rotation of the rotor) is synchronously to the pulse
frequency (= rotating stator field in the motor).
In case of a load at the motor (e.g. via a static load at the motor shaft or because of accelerating
the motor – dynamical load) the running of the motor will differ from the pulse frequency within
a short time and within a certain max range.
This results in a change of the load angle (= difference between the real position of the rotor and
its position command value).
By using an encoder, mounted at the motor, the load angle can be monitored, and a mechanical overload at the motor can be detected.
