What is the lifespan of a brushless motor?
Brushless is a type of AC motor. In reality, there are many industrial AC motors that have been used for 3-4 years. After all, as long as the bearings are not damaged, there is no problem. The general service life is over 20000 hours. Under normal operating conditions, if used for more than 5 years, it will not be damaged, so the lifespan of DC brushless motors is 5 times that of traditional motors.
How are brushless motors classified?
Brushless motors with phase angles of 60 ° and 120 °; According to speed, there are high-speed brushless motors and low-speed brushless motors; According to whether the motor has a position sensor, there is a brushless motor with a position sensor, and a brushless motor without a position sensor.
According to the type of motor, it can be divided into: brushless motor with iron core, brushless servo motor with iron core, brushless motor with hollow cup, brushless servo motor with hollow cup, etc
How to maintain brushless motors？
The Hall element is the most easily damaged component in brushless motors, followed by the coil. Because Hall elements are afraid of static electricity, water, high temperatures, rust, high currents, etc., the following points should be taken into account when using them:
1. In summer, do not let the motor be exposed to sunlight for a long time. After a long period of time, it is best to stop the bicycle and let the motor heat up;
2. On rainy days, try not to drive bicycles into waterlogged areas. If it is unavoidable, ensure that the motor shaft is not submerged in water;
3. Do not drive on excessively unstable roads and do not malfunction bicycles for a long time;
4. Do not use for inferior batteries and controllers.
