A scooter motor includes a stator unit, a rotor unit and a brake unit. The stator unit is fixedly mounted on the fixed shaft of the motor, and the rotor unit is rotatably mounted on the fixed shaft. The brake unit includes a friction plate component and an electromagnetic clutch component. The electromagnetic clutch component is configured to drive the friction plate component to press to brake. According to the embodiment of the present invention, the scooter motor drives the rotor unit to rotate by the cooperation between the stator unit and the rotor unit to drive the scooter, additionally, the stator unit controls the rotation of the rotor unit by using the friction plate component and the electromagnetic clutch component to realize the braking of the scooter.

The centrifugal positive locking brake works inversely, that means, locking upon stopping and decoupling on start-up. When the drive motor is de-energized, the fixed ratchet(s) hit against at least one locking abutment on a locking disc positively fixed to the frame and lock the shutter. When voltage is applied, and with the associated quick start-up of the drive motor , the ratchet(s) disengage because of their inertia. This centrifugal positive locking brake for shutter drives is operated with a specially designed control method. After the power supply is interrupted, the ratchet(s) are drawn inward by the reloaded spring(s) so that they run against the locking abutment(s) and the shutter reliably locks in this position.

To reduce abnormal noise production in a friction brake structure, the friction brake structure includes: a brake plate 20 fixed to a rotating shaft 15 of a rotary electric machine 1; a ring-shaped brake shoe 30 disposed facing the brake plate; and a brake shoe support plate 40 which engages with a fixing portion of the rotary electric machine so as to be movable in an axial direction, and which supports the brake shoe and is biased by biasing action so as to bring the brake shoe into sliding contact with the brake plate.

A motor brake device includes an armature base, an armature plate, a fixing plate and at least one brake lining. The armature plate is disposed on the armature base. The armature plate is vertically movable relative to the armature base. The fixing plate is fixed on the armature base. The fixing plate and the armature base are located at two opposite sides of the armature plate. The braking assembly is arranged between the armature plate and the fixing plate, and includes a two-winged rotor hub plate, a brake friction plate and at least two elastic elements. The at least one brake lining is arranged between the armature plate and the braking assembly and/or between the fixing plate and the braking assembly.

An adjustment unit, particularly for use in a commercial vehicle brake, comprising a stator and a rotor, wherein the stator and/or rotor have a coil arrangement, wherein the rotor is mounted in such a way that it can rotate about an actuation axis relative to the stator, and the stator is secured in such a way that it cannot rotate about the actuation axis relative to a main body, wherein it is possible to generate, in the coil arrangement, a magnetic field which rotates the rotor relative to the stator, wherein the rotor is in engagement with a first transmission section in such a way that a rotation of the rotor results in shifting of the first transmission section relative to the stator along the actuation axis.
