Motor is widely used in our daily life, the most common is the wholesale dc motor, so today's popular science is the characteristics and classification of dc motor.
The principle of dc motor is very simple, namely, the alternating electromotive force in the coil is changed into dc electromotive force through the action of the commutator.Dc motor is a simple motor, dc motor has the advantages of good speed regulation performance, starting power, low noise, small energy consumption, widely used in life.
Dc motor can be divided into brushless dc motor and brushless dc motor. The difference between brushless dc motor and brushless dc motor lies in the energization mode of stator and rotor. The stator of brushless dc motor is energized by a coil, while the rotor of brushless dc motor is energized by a coil.Generally speaking, the energy conversion efficiency of brushless motor is higher than that of brushless dc motor, and the service life of brushless dc motor is longer than that of brushless dc motor, because the carbon brush of brushless dc motor needs to be replaced frequently due to friction and wear. Brushless dc motor is the development direction of motor in the future.
