Electric motor is not a harmonious movement

摘要

The invention relates to the stepper motors. / p & & p & it relates to a stepper motor having a cylinder or rigid tubular rotor 30 placed in a stator is provided in a case, the stator atant a ring has inner toothing 46 which co-operates with a ring has outer toothing 42 reach by the cylinder. A flexible diaphragm 32 supports the rotor, which can thus be subjected to an angular displacement lightweight when the poles of the stator are powered and rotate the rotor, which thus has an orbital movement. / p & & p & application to the embodiment of the electrical motors, stepper.
