1, according to the nature of the load and production processes of machinery, motor starting, brake, reverse, speed requirements, a reasonable choice of the type of motor.

    2, according to the requirements of the load torque, speed range and start frequently, consider the limit of the temperature rise of the motor, overload capacity and starting torque, a reasonable choice of motor power, reasonable power matching, and strive to safe, reliable and economic.

    3, according to the environmental conditions of the use of premises, such as temperature, humidity, dust, rain, gas, corrosive and flammable gas content, etc., to consider the necessary protection mode, and select the motor protection structure type.

    4, according to the the enterprise grid voltage standards and the requirements of the power factor, determine the voltage rating of the motor.

    5, according to the maximum speed of the production machinery and electric drive speed control system and mechanical reduction of the complexity of, select the rated speed of the motor.

    6, the choice of motor, to consider the price of the product, construction and operating costs, and strive to overall economic efficiency of the best. In a dry, clean place, you should try to IP23 series motor; For continuous operation, the load of the load is high, should adopt the high-efficiency motor, in order to save energy and improve the overall economic benefits.

    7, the choice of motor, to consider the affect the installation, operation and maintenance factors, and strive to install and easy maintenance, reliable operation.

    8, to implement the country's technical and economic policies, and actively state explicitly promote new products, do not be out of the product.
