Brushless DC geared motors can also be called "brushless DC motors, brushless motors, high power brushless motors". It is characterized by the following points:

　　1, the market more end of the high-power miniature DC brushless external rotor motor.

　　2, the motor features rotor magnets distributed in the inner wall of the motor shell, the stator coil is located in the center of the motor.

　　3, motor external characteristics for the output end cover fixed, motor shell rotation, out of the line 3, no Hall.

　　4、Usage:

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

　　B. The steering and speed of the motor is adjusted by the brushless actuator or by adding external signals.

　　5、The motor adopts performance neodymium earth magnet multi-slot winding process to get good comprehensive performance.

　　6、Motor performance is superior, efficiency of more than 75%.

　　7, the motor without carbon brush wear, long life, general service life of 1-2 million working hours.

　　8, motor outer rotor structure, rotor torque, good heat dissipation, you can get high power. Gear motor is not unfamiliar to most people, gear motor between the prime mover and the working machine or actuator to match the rotational speed and transfer torque, is a relatively precise machinery. However, due to the harsh working environment of geared motors, wear and leakage and other faults often occur.

　　For the failure to occur, we must first understand the use of geared motors have what skills.

　　First, the user should have a reasonable use of maintenance rules and regulations, the operation of the gear motor and inspection of the problems found in the work should be carefully documented, when found in the oil temperature rises above 80 ℃ or oil pool temperature exceeds 100 ℃ and produce abnormal noise and other phenomena should be discontinued, check the cause, must be eliminated, replace the lubricating oil, before continuing to operate.

　　Second, the oil change should wait for the gear motor to cool down without the risk of combustion until, but still should keep warm, because after cooling, the viscosity of the oil increases, oil discharge difficulties. Attention: cut off the power supply of the transmission device to prevent unintentional energization.

　　Third, in the operation of 200 ~ 300 hours, should be carried out after the second oil change, in the subsequent use of the oil should be regularly checked the quality of the oil, for mixed impurities or deterioration of the oil must be replaced in a timely manner. In general, for long-term continuous work of the gear motor, according to the operation of 5000 hours or once a year to replace the new oil, long-term out of service of the gear motor, in the re-operation of the motor should also be replaced before the new oil. Gearmotors should be added with the original grade of the same oil, not mixed with different grades of oil, the same grade but different viscosity oil is allowed to mix.

　　Brushless motor's application field: Brushless motor's remarkable feature is that it has strong explosive force, fast speed and KV value, which is especially important for some occasions that need speed and explosive force, such as the aeromodelling motors used in small flying machines and edge grinders. Match with speed reducer: Since the outer rotor brushless motor rotates very fast, it is usually matched with small speed reducer.
