Introduction: In order to make the motor the most efficient in use, the capacity and model of the motor must be reasonably selected according to the different properties of the load. If the motor capacity selection is too large, it will not only cause waste of investment, but also the efficiency and power factor are not high, so that the power is wasted a lot.

The use of high efficiency and energy saving is the pursuit of every user. The following Anhui Wannan motor technology tells you how to use the most efficient and energy-efficient method of motor.

1. In order to make the motor the most efficient in use, the capacity and model of the motor must be reasonably selected according to the different properties of the load. If the motor capacity selection is too large, it will not only cause waste of investment, but also the efficiency and power factor are not high, so that the power is wasted a lot. If the capacity of the motor is too small, it will be difficult to start, or it will barely start up, and the working current will exceed the rated current of the motor, causing the motor winding to overheat and even burn out.

2. When selecting the motor capacity, the capacity of the power supply transformer should also be considered. Generally speaking, the capacity of the largest asynchronous motor directly started should not exceed 1/3 of the capacity of the power supply transformer.

3. For motors that run continuously, such as pumps and pumps, from the point of view of energy saving, the motor has the highest efficiency when it is operated at a load rate of about 80%. For agricultural motors, the highest efficiency is achieved when operating at an average load rate. Therefore, when the average load of the agricultural motor is 70% or more of the rated capacity of the motor, the selection of the motor capacity is considered to be reasonable.

4. For short-running motors, for example, motors with electric gates, which can be operated at a greater than rated power, should be determined based on whether the torque of the motor can meet the load torque requirements.
