1、 Brushless motor (DC brushless water pump)

A brushless DC motor is composed of the main body of the motor and the driver. Brushless motor is a typical electromechanical integrated product. Due to the controlled operation of brushless DC motors, they do not like the variable frequency speed regulation of synchronous motors. For example, brushless motors with starting windings on the rotor do not experience oscillations or sudden step changes in load. Brushless motor, low-power brushless DC motor, permanent magnet brushless motor, and now the use of rare earth neodymium iron boron high magnetic energy product (neodymium iron boron) data. Therefore, the volume ratio of the reduced frame size of rare earth permanent magnet brushless motors to three-phase asynchronous motors of the same capacity.

The structure of a brushless motor is similar to that of a brushless motor, but the rotor and stator of a brushless motor are exactly the opposite; The rotor brushless motor is connected to the coil winding brushless motor and the power output shaft, and the permanent magnet brushless motor stator rotor magnet is used; The brushless motor is a permanent magnet connected to the output shaft of the housing. The stator winding coil of the brushless motor is used to select the magnetic field for reverse electric replacement. The brushless motor is a brushless motor (brushless motor).

2、 The operating principle of brushless motor (DC brushless water pump)

A simple brushless motor, the frequency and waveform of the input communication current waveform of the brushless motor are modified. The stator coil of the brushless motor is wound around the magnetic field to form a rotating motor that drives the permanent magnet rotor magnetic field. The number, function, and magnetic field strength of the brushless motor when it rotates, the input voltage of the motor, and the control function of the DC brushless motor are closely related to the brushless motor. Since the input is a DC brushless motor, it is directly connected to the brushless motor.

Now the demand has become a cross point for electronic speed controllers and DC brushless motors, and it also needs to accept control signals from remote controllers. The brushless motor controls the speed of the motor to meet the needs of brushless motor use. Brushless motors have a relatively simple structure and can be equipped with either physical components or electronic speed controllers. They require excellent control program design, circuit design, and complex processing procedures. Therefore, the price of brushless motors is much higher than that of brushed motors.
