Abstract
The utility model discloses a motor which comprises a rotating shaft and a centrifugal switch device. The centrifugal switch device comprises a centrifugal sliding block, an elastic piece provided with a movable contact, and an insulation fixation plate provided with a first static contact and a second static contact. The centrifugal sliding block is sheathed on the rotating shaft and can slide on the rotating shaft. The movable contact can move between the first static contact and the second static contact with the centrifugal sliding block until the movable contact abuts against the first static contact or the second static contact. The basic shape of the insulation fixation plate is U-shaped. The insulation fixation plate comprises a base region and two connection regions which are separated on both sides of the rotating shaft. The elastic piece comprises an arc-shaped electrical connection plate region on which the movable contact is arranged, mounting plate regions which are fixedly arranged on the connection regions on the insulation fixation plate and U-shaped elastic plate regions. The electrical connection plate region is fixedly arranged on the centrifugal sliding block. The centrifugal sliding block drives the electrical connection plate region to carry out reciprocating movement. According to the utility model, the structure is reasonable and simplified; fault sources are less; and the working performance is stable and reliable.
