What is the difference between DC brushless geared motor and DC brushed geared motor? The following motor manufacturer Lihui Xiaobian will share it for everyone.

First, the shortcomings of DC brushed geared motors
1. The friction is large, and the customers with large losses often encounter this problem when using the brushed geared motor. That is, after using the brushed geared motor for a period of time, it is necessary to open the motor to clean the carbon brush of the brushed geared motor, which is time-consuming and laborious. This is equivalent to disassembling the entire motor and assembling it.
2. Large heat and short life due to the structure of the brushed motor, the contact resistance of the brush and the commutator is very large, resulting in a large overall resistance of the motor, which is easy to generate heat, and the permanent magnet is a heat-sensitive element, if the temperature is too high If the magnetic steel is demagnetized, the performance of the motor will be degraded, which will affect the life of the brushed motor.
3. Low efficiency, low output power The heating problem of the brushed motor is mentioned above. The reason is that the current is working on the internal resistance of the motor, so the electric energy is converted into heat for a large degree, so there is a sword dance motor. The output power is not large and the efficiency is very low.

Second, the advantages of DC brushed motor
Brushed motor with excellent low-speed torque and high torque

Third, the advantages of DC brushless geared motor
1. No carbon brush, low interference The brushless gear motor removes the carbon brush. The most direct change is that there is no spark generated when the brushed motor is running, which greatly reduces the interference of the spark to the remote control radio.
2, low noise, smooth operation Brushless motor has no brush, the friction is greatly reduced during operation, smooth operation, low noise, this advantage is a huge support for the stability of the brushless motor.
3, long life, low maintenance costs less carbon brush, the wear of brushless geared motor is mainly in the bearing, from a mechanical point of view, the brushless geared motor is almost a maintenance-free motor, when necessary, only Need to do some dust removal maintenance.
