As we all know, NdFeB magnet tiles or NdFeB radial magnetic rings are as important as the human heart in motor products. After the current is energized, the magnetic field generated by the coil drives the NdFeB magnet tiles or NdFeB radial magnets. Ring magnetic field, therefore, the magnetic field strength of NdFeB magnet tiles or NdFeB radial magnetic ring is very important to the operating efficiency of the motor. Let's first take a look at the advantages of brushless motors:
1)Brushless, low interference
The brushless motor removes the brush, and the most direct change is that there is no spark generated when the brushed motor is running, which greatly reduces the interference of sparks to remote control radio equipment.
2)Low noise and smooth operation
The brushless motor has no brushes, so the friction during operation is greatly reduced, the operation is smooth, and the noise is much lower. This advantage is a huge support for the stability of the model's operation.
3)Long service life and low maintenance cost
Without brushes, the wear of brushless motors is mainly on the bearings. From a mechanical point of view, brushless motors are almost maintenance-free motors. When necessary, just do some dust removal maintenance. Brushless motors, as the name suggests, do not require original carbon brushes. A magnetic field is formed around the winding coil that rotates around the geometric axis of the motor. This magnetic field drives the permanent magnets on the rotor to rotate, and the motor starts to rotate. The performance is related to the number of NdFeB magnetic tiles, the magnetic flux intensity of the NdFeB radial magnetic ring, the size of the motor input voltage and other factors. What really determines its performance is the brushless electronic speed regulator.
