1, to the continuous operation of the motor, such as motor with water pump, fan, etc, from the viewpoint of energy saving, motor running about 80% load rate, the highest efficiency. Operation of farm motors, and its average load rate, the highest efficiency. So, for agricultural motor, the average load of the motor more than 70% of the rated capacity, can think of the choice of the motor capacity is reasonable. 2, to the short time run of motor, for example, and form a complete set of electric gate motor, can allow the run than rated power is larger, it should be in accordance with the torque of the motor can meet the requirement of load torque. 3, to make the highest efficiency in the use of electric motor, must according to the load capacity and reasonable choice in terms of the different nature of the motor model. Such as the motor capacity choice 徃 slants big, not only cause the waste of investment, and also is not high efficiency and power factor, the electric energy waste is very large. The capacity of the motor selected too small, will be hard to start, or just starting up, work more than the rated current of the motor current will flow, lead to overheating and burning motor winding. 4, when choosing motor capacity, and considering the size of the power supply transformer capacity, in general, direct the biggest l of asynchronous motor starting capacity, should not be more than a third of the power supply transformer capacity. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
