At present, a variety of alloys motor shell in the market, but overall there are stretch forming metal plate shell, casting metal casing, cold extrusion molding and forming a four alloy tube. Because of its low density, light, and convenient processing, is widely used in many fields.


It is understood that the cold extrusion blanks, turning machining of metal alloy shell structure of rough, after cold extrusion, it needs timely processing, precision machining surface after Anodic oxidation processing is required.

1.leakage protection

Motor shell have ground fault protection and leakage protection. Earthing protection of current signal from the internal current transformer and, for protection of the lines on the metal casing of the motor short circuit protection, motor shell can increase leakage transformer, 30mA~50mA fault current is detected, mainly for non-direct earthing protection in order to ensure personal safety.


2.External fault protection

When the motor casing has an external fault has been detected, External fault switch input and switch input status of the motor shell definition is inconsistent, motor shell set to protect and ensure the safety of motor apparatus.


Fengli precision casting factory through 6S management system, involving every detail of the production process of castings. Produced in a variety of motor casing need to be checked, nonconforming products or reworked or eliminated, must not be allowed into the market, each process of the production of first article inspection and do a record, during the inspection process, ultimately after total qualified before being rolled out. Therefore, our customers can rest assured that purchasing our product, I believe our product can make you satisfied!
