The terminal box cover is specially casted to protect and stabilize the stator and rotor increasing the surface contact between the frame and iron core. This improved the rigidity of the frame,and motor vibration is reduced, thus increasing the bearings and the motor service life.Internally, the stator and rotor winding terminal were design to exit through an IP gland, preventing accidental dropping of connecting bolts and nuts into the windings of the motor. Safe motor operation is ensure and protected.
Within the groove design are drainage holes with IP plug at both ends for better operation in high humidity enviroment. The motor coil insulation is intact and protected.
The drainage groove inside can also be utilized for leads slot feed through internally and neatly connection at the terminal box such as leads from brakes, temperature devices for bearing/winding (PT100) and heaters. The leads are not exposed.
Design a new type of pressure casting mold for cast aluminum rotor production. The mold designed with exhaust structure can solve the exhaust's problem now in the common mold design. This can enhance the quality of the casting products.
