tractor motor

tractor motor 1. The stator and rotor windings are vacuum-pressure impregnation processed so that the whole insulation performance of the generator is excellent and dependable, and also its mechanical strength is higher. A special insulation structure is used for the rotor, forming a strong ability against the highfrequency harmonic impulse from frequency converter. 2. The stator windings and bearings of the tractor motorare fitted with the platinum thermistor Pt100 for monitoring and controlling the winding and bearing temperatures. 3. The bearings are quipped with an automatic grease-charging system and a manual grease- charging system,for users free operating selection. 4. The slipring system on the electric motoris fitted with a brush-worn alarm unit. 5. A lightning protection device for stator and rotor can be mounted according to users demand.The insulation bearings or a bearing-insulating system and the earthing brushes are applied to eliminate the influence of shaft current. 6. A space heating system working at a standstill of the generator is builtin.
