Abstract
A single-shaft brushless motor comprises a stator, a rotor and a motor shaft. The stator is a coil assembly. The coil assembly comprises magnetic steel, a silicon steel sheet and a steel sheet support. The motor shaft is installed in the steel sheet support. A lead wire of the motor is led out from one end of the motor shaft. The motor shaft is connected with a disc brake end cover through a bearing. An outer end of the disc brake end cover is provided with a disc brake sheet. The other end of the motor shaft is provided with a double-row tapered roller bearing. An outer end of an inner circle portion of the double-row tapered roller bearing is provided with a bearing pressing sleeve. An outer circle of the double-row tapered roller bearing is fixed in a shaft hole of an output end cover. An outer end of an outer circle portion of the double-row tapered roller bearing is provided with a clamping spring. The output end cover is connected with the disc brake end cover through a motor shell iron ring so as to form a rotor. The motor shaft is installed on a vehicle frame of a vehicle. The output end cover is connected with a wheel hub of the vehicle through a bolt. When the vehicle carries out cornering at a high speed, a generated side (axle) direction force is directly transmitted to the vehicle frame through the double-row tapered roller bearing so that a damage of an inclination force to the motor is completely overcome; stability and security during driving are increased.
