The difference of performance between brush and no brush motor introduced rc brushless motor suppliers
The DC brush motor has the advantages of low cost and convenient maintenance. Because DC brush motor has simple structure, low production cost, many manufacturers and mature technology, it is also widely used, such as factories, processing machine tools, precision instruments, etc. if the motor fails, you only need to replace the carbon brush, each carbon brush only needs a few yuan, which is not often cheap. The technology of BLDCM is not mature, the price is high, and the application scope is limited. It should be mainly used in constant speed equipment, such as frequency conversion air conditioner, refrigerator, etc. if the BLDCM is damaged, it can only be replaced.
No brush, low interference
The most direct change is that there is no electric spark generated when the brush motor is running, which greatly reduces the interference of the electric spark to the remote control radio equipment.
Low noise, smooth operation
Without the brush, the friction is greatly reduced, the running is smooth, and the noise is much lower. This advantage is a huge support for the running stability of the model.
Long life, low maintenance cost
Without electric brush, the wear of the brush less motor is mainly on the bearing. From the mechanical point of view, the brush less motor is almost a maintenance free motor. When necessary, it only needs to do some dust removal maintenance.
