1. Principle of selecting motor
In order to adapt to various uses, motor manufacturers have produced different types, forms and capacities of motors. When choosing a motor, it is necessary to fully consider their characteristics, and after carefully studying the characteristics of the dragged machine, choose a motor suitable for the load characteristics.
The principle of selecting the motor is:
(1) According to the starting characteristics and operating characteristics of the load, select the most suitable motor for these characteristics to meet the various requirements of the production machinery during the work.
(2) Select a motor with a protection method and a cooling method suitable for the environment of the place of use, and the structure should be suitable for the environmental conditions of the motor.
(3) Calculate and determine the appropriate motor capacity. Generally designed and manufactured motors have the highest efficiency at 75%-100% rated load. Therefore, the difference between the capacity required by the equipment and the capacity of the selected motor should be minimized so that the power of the motor can be fully utilized.
(4) Choose a motor with high reliability and easy maintenance. Electric motor
(5) Consider the interchangeability, try to choose a standard motor.
(6) In order to make the whole system operate efficiently, the number of poles and voltage level of the motor must be considered comprehensively.
2. The general steps for selecting a motor can be considered as follows-
(1) According to the requirements of production machinery, choose the type of motor.
(2) Select the rated motor voltage according to the power supply.
(3) Select the number of revolutions of the motor according to the number of revolutions required by the production machinery and the condition of the transmission equipment.
(4) According to the installation location and site environment of the motor and production machinery, choose the structure and protection form of the motor.
(5) Select the rated power of the motor according to the power capacity required by the load and the operating mode of the motor.
When doing motor selection, we must prepare more product catalogs of several manufacturers and brands at hand, and then comprehensively consider the above factors to select the most suitable motor.
