Stepper motor e.g. permanent magnet type, or variable reluctance or hybrid type

摘要

The stepper motor has a circuit board (50), a stator (20,30) with a drive winding (27), a (40) rotor with a rotor shaft (41) and rotatable by magnetic force, electrical connections (28a) extending outwards from the stator at different angular directions and electrical insulation bodies (26f). Each connection is connected to the drive winding and has one end section inserted into the circuit board in the axial direction of the rotor shaft and connected to the circuit board. The insulation bodies hold the other ends of the connections securely on the stator.
