How to choose a suitable brushless motor?

Motors are widely used in many industries, among which the power plant equipment industry is the most prominent. Of course, the motor may cause various malfunctions when it is in operation because of improper use by users. If the motor has malfunctions, it must be solved in time. Otherwise, the service life of the motor will be shortened. The following chapters describe the selection of motors. Choose knowledge.

1. Choose the motor form according to the different installation location of the motor. For example, in inflammable and explosive places of petrochemical industry, explosion-proof motors should be chosen. In other places, open motors can be used. Where there is more dust and water droplets splash, closed Motors should be used.

2. Determine the power of the motor according to the load usage. The power of motor should generally be 1.1-1.5 times of the power of production machinery. If the power selection is too large, it will not only increase the investment, but also reduce the mechanical efficiency and increase the production cost. If the power selection is too small, the motor will endure long-term overload, which will cause excessive temperature rise and damage the insulation, and shorten the service life of the motor.

3. Select the motor according to the speed requirement of the working machinery and the transmission mode of the reducer. The principle of speed matching is to make the motor and production machinery run at rated speed, and the transmission mode is the same.
