Working principle of permanent magnet brushless DC motor: The stator of the brush motor is provided with a fixed main magnetic pole and an electric brush. The electric energy of the DC power supply enters the armature winding through an electric brush and a commutator, and the armature current is generated. What are the permanent magnet brushless DC motor: Brush type winding motor. The utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that the utility model is characterized in that. Motor phase is adjusted by mechanical phase shifter. Mechanical commutation device is fixed on the carbon brush and the rotating copper change to adjust the voltage phase of the friction surface. Brush printed winding motor. The utility model relates to a brush printed winding motor which is used for printing a copper foil plate as a winding. Because this kind of motor is produced in the automatic production line, the process is reliable, so that the life of the motor is increased to 3000h, the noise is greatly reduced and the efficiency is increased to 72% ~ 76%. Brush winding motor The electric motor can be compressed into a new type of winding through the winding copper wire, and the efficiency can be increased to 74% ~ 78%. This motor is still being used by many electric bicycle manufacturers. If you have any questions, please call our company, our company will give you the most detailed answer.
