Electric motor manufacturer teaches you how to choose the right motor correctly

Electric motor refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction, and has a wide range of applications in various industries. So how to choose the appropriate motor? Generally, the following points are considered:

1. The specific selection depends on the situation you are using, load size, speed requirements, as well as on-site power supply, site size, and other conditions.

2. The motor power should be selected based on the power required by the production machinery, and the motor should be operated at rated load as much as possible. If the motor power is selected too low, it may cause long-term overload of the motor. Damage to its insulation due to heating. Even the motor was burnt out. If the motor power is too high, the output mechanical power cannot be fully utilized, the power factor and efficiency are not high, and it can also cause waste of electrical energy. Determine whether to use single-phase or three-phase motors, high-voltage or low-voltage motors based on power. Then select the voltage level and capacity based on the power supply and actual power size.

3. Based on your requirements for motor speed, such as whether a small change in speed is allowed after a load change. If so, it is recommended to choose an asynchronous motor. Otherwise, only synchronous motors can be used. Also, is there a requirement for multi-level variable speed? If so, a frequency converter or series resistance variable speed should be added to the control.

4. Select the number of motor poles based on the speed range.

5. Some motors with the same power also have large, medium, and small bases, etc., which can be selected according to on-site requirements.
