2, the rear bearing of motor adopts the plastic sheath of being made by high performance plastic material, replaced the like product oiliness bearing, not only size is short, and when avoiding oiliness bearing to use one section after date because the volatilization of oil, make motor noise big, the defective that useful life is short can avoid the oil of oiliness bearing volatilization to be embedded in the defective that causes short circuit in the groove of commutator with the carbon dust bonding simultaneously again.
3, in light weight, material is economized, part is few.Compared with similar products, brush basin base plate, asphalt felt, brush carrier, bearing gland, axle sleeve compressing tablet have been saved.
4, cost performance height.Especially and then descend at the continuous price that requires part that descends of the price of automobile market car, and raw material such as copper material, steel go up a lot, simultaneously, user's standard is improving.This motor satisfies user's harsher requirement with its low cost, high performance advantage, has broken through the unapproachable high performance-price ratio of general motor, thereby has made product have more competitiveness.
5, applicability is wide.Can promote the use of the fan electromotor of all size power, can supportingly be used for high, medium and low shelves automobile, car, especially economical, compact car, be more suitable for being used for the narrow and small car in enging cabin space, and the conventional fan motor can't satisfy more small size, more powerful requirement, thereby opened up market, will win more user.
