The recorder play bldc motor is a motor without brushes and commutators, which can also be called a commutatorless motor. The rotor of a brushless motor is a permanent magnet and the stator consists of multiple windings. It is equivalent to flipping the structure of the traditional DC motor from the inside to the outside. The windings are connected to a control circuit, which acts as a commutator and is responsible for activating the corresponding appropriate windings.

　　The recorder play bldc motor windings are activated one by one according to the direction of rotation, and the magnetic poles of the activated stator windings attract the magnetic poles of the rotor, switching when the aligned position is reached. The brushless motor for DC recorder playback can be configured as single-phase, double-phase and three-phase according to the number of stator windings. Among them, three-phase is the most widely used.

　　First of all, without brushes and commutators, the development of traditional DC motors is limited to high-speed and large-capacity motors. Several factors, such as commutation sparks, mechanical strength of commutators, brush wear and other issues, are all changed by changing commutation conditions. method is well resolved.

　　The recorder play bldc motor can run at low speed and high power, which can save the need for the reducer to directly drive large loads; excellent torque characteristics, good torque performance at medium and low speeds, large starting torque, and small starting current; stepless speed regulation, Wide range of speed regulation, strong overload capacity, etc. Furthermore, the recorder play bldc motor is resistant to bumps and vibrations, low noise, small vibration, smooth operation and long life.
