Soft start motor

A soft start motor comprises a housing, and a stator and a rotor positioned in the housing. The rotor comprises an output shaft and a magnet steel on the output shaft. A bearing is arranged on the output shaft. A front end of the housing is provided with a front cover. The output shaft penetrates through the front cover. The front cover is supported on the bearing. A brake block is sleeved onto the output shaft between the magnet steel and the bearing. A back pressure spring is provided between a back end of the brake block and the magnet steel. A spline pad is provided on the output shaft. The spline pad is positioned between the brake block and the bearing. A front pressure spring is provided between the spline pad and the brake block. A spline slot matched with the spline pad is arranged on the brake block. Under the condition of no braking, the motor operates normally; and under the absorption effect of the magnet steel, the brake block does not contact the front cover. Under the condition of stopping and
