Brief Construction
The motor adopts compacted box structure, welding-jointed steel plate forits frame, light weight, rigid in construction, there is closed air to air coolers on the stator frame convenient for installation and maintenance.
Stator winding adopts F class insulation and its end adopts firm binding. The whole stator adopts solvent-free varnish Vacuum pressure impregnation(VPI) to ensure the stator has excellent electric property and humidity resistance.
Rotor is made of cast aluminium or copper bar. Aluminium rotor is made of pure aluminium, copper barwedging copper rotor enhances the entorety of rotor.
The motor adopts rolling bering or sliding bering, according to the output power and rotary speed. Bearing protection grade normally is IP44. If the motor's protect grade increases, so does the berings'. Rolling bearing adopts iubricating gresse and its grease charger and discharger can be charged or discharged without stopping the motor.
The junction box is of IP54 protection grade and it is usually mounted on the motor's right side(viewed from shaft extension end.) It is also can be mounted on the left side and its outlets have four optional orientations(up, down, left or right.) Separated grounding unit is available in main junction box, too.
