Brushless DC gear motors can also be called "DC brushless motors, brushless motors, high-power brushless motors". Its characteristics are as follows:

1. The relatively high-end high-power miniature DC brushless external rotor motor on the market.

2. The characteristic of the motor is that the rotor magnets are distributed on the inner wall of the motor housing, and the stator coil is located in the center of the motor.

3. The external feature of the motor is that the output end cover is fixed, the motor shell rotates, and there are 3 wires outgoing, and there is no Hall.

4. In terms of use:

A. It must be used with a dedicated brushless drive, and the motor is a three-phase motor.

B. The steering and speed of the motor are adjusted by brushless actuators or external signals.

5. The motor adopts high performance neodymium magnet multi-slot winding technology to obtain good comprehensive performance.

6. The motor has superior performance, with an efficiency of over 75%.

7. The motor has no carbon brush wear and has a long service life, generally between 10,000 and 10,000 working hours.

8. The outer rotor structure of the motor has large rotor torque, good heat dissipation, and high power can be obtained. The geared motor is familiar to most people. The geared motor plays a role in matching the speed and transmitting torque between the prime mover and the working machine or actuator. It is a relatively precise machine. However, due to the harsh working environment of the geared motor, failures such as wear and leakage often occur.

In order for the failure to occur, we must first understand the use skills of the geared motor.

1. The user should have reasonable use and maintenance rules and regulations. The operation of the geared motor and the problems found in the inspection should be carefully recorded. Stop using it under normal noise and other phenomena, check the cause, troubleshoot the fault, and replace the lubricating oil before continuing to run.

2. When changing the oil, wait for the geared motor to cool down and there is no danger of burning, but it should still be kept warm, because after cooling, the viscosity of the oil will increase and it will be difficult to drain the oil. Note: Cut off the power supply of the transmission device to prevent accidental power on.

3. After 200 to 300 hours of operation, the oil should be changed twice. In the future use, the quality of the oil should be checked regularly, and the oil mixed with impurities or deteriorated should be replaced in time. Generally, for the geared motor that works continuously for a long time , Change the new oil according to the operation for 5000 hours or once a year, and the geared motor that has been out of service for a long time should also be replaced with new oil before re-operation. The geared motor should be added with the same oil as the original brand, and must not be mixed with different brands of oil. The same oils with different viscosities are allowed to be mixed.

Application areas of brushless motors: The remarkable characteristics of brushless motors are strong explosive power, fast speed, and KV value. It is especially important for some occasions that require speed and explosion, such as model airplane motors and edge grinding machines used in small aircraft. Matching with reducer: Because the outer rotor brushless motor rotates very fast, it is generally matched with a small reducer.
