The DC brushless motor will have a certain load during normal operation, but this load is not unlimited. Once the load is exceeded, the motor is in a load state. If the motor is under load for a long time, the efficiency and life of the motor will be generated. Bad influence, how to control the load of the motor?
1. The rated state of the DC brushless motor refers to the rated power, that is, the rated shaft output power, such as a 22KW motor, its rated shaft output power is 22KW.
2. Note that the rated power of the motor can not be higher, because if it is higher, it will burn the motor, if it is lower, it will reduce the efficiency of the motor. Therefore, it is very important to control the rated load of the motor.
3. The rated load and rated state are the same as the mechanical load connected to the output shaft of the brushless DC motor and the output power of the motor label. Greater than or less than is not rated. Therefore, the values of rated load and rated state are basically constant.
