Claim 0:
1. A scooter motor, comprising:
a stator unit, wherein the stator unit is fixedly mounted on a fixed shaft of the scooter motor;
a rotor unit, wherein the rotor unit is rotatably mounted on the fixed shaft;
a brake unit, wherein the brake unit comprises a friction plate component and an electromagnetic clutch component;
an electromagnet, wherein the electromagnet is sleeved on the fixed shaft and the electromagnet is fixedly connected to the fixed shaft;
an armature, wherein the armature is sleeved on the fixed shaft and the armature is configured to slidably cooperate with the fixed shaft; and
an elastic member, wherein the elastic member is configured between the armature and the electromagnet; wherein the electromagnetic clutch component drives the friction plate component to press the brake when the scooter motor is de-energized;
the friction plate component comprises a plurality of movable friction plates and a plurality of fixed. friction plates, wherein
the plurality of movable friction plates and the plurality of xed friction plates are stacked at intervals;
the plurality of movable friction plates are linked with the rotor unit, and the plurality of fixed friction plates are slidably mounted on the fixed shaft and the plurality of fixed friction plates are limited in rotation;
the electromagnetic clutch component drives the plurality of fixed friction plates to press the plurality of movable friction plates to brake when the scooter motor is de-energized; and
the electromagnet is configured to be de-energized, and the armature is configured to press the friction plate component under an action of the elastic member to brake when the scooter motor is de-energized.
