Surface-mounted miniature electric motor for printed circuit board e.g. for measuring mechanism for automobile dashboard instrument, has contact springs at ends of stator coil winding for contacting circuit board conductor paths

摘要

The electric motor has a number of coils (1) and stator plates extending between the coils and the rotor, with pre-stressed contact springs (4) provided at the coil winding ends (6) and biased into contact with respective printed circuit board conductor paths, when the electric motor is mounted on the printed circuit board.
