AC motor Housing selection is important. The type, structural model, protection mode, capacity and speed of AC motor Housing shall be determined according to the nature, torque, speed, starting, braking and acceleration requirements of the loaded machinery. The type selection of motor must meet the use requirements. Motors for special purposes and operating conditions must be specially designed and treated with special processes to meet the special requirements. Economic rationality shall also be considered in the selection of AC motor Housing. For example, load machines that do not need speed regulation and frequent start, such as water pump, fan, belt conveyor and small machine tool, can be driven by asynchronous motor, which is not only cheap, but also easy to use and maintain. For load machines that do not need speed regulation, long-term operation or heavy load start, such as ball mill, large air compressor and non speed regulation steel rolling mill, Large synchronous motor can be used to apply, which is characterized by large overload torque and stable operation, which is conducive to improving the power factor. For the rolling mill that needs forward and reverse rotation and speed regulation, the shovel that often has locked rotor and the mine winch that frequently starts and brakes, the DC motor with good speed regulation performance, good control performance and rapid forward and reverse rotation shall be used.
