3.结构说明 Brief Construction

3.1 电动机为国际流行的箱式结构,机座和端盖均由钢板焊接制成,刚度好,重量轻,电动机顶部采用封闭式空-空冷却器,拆装方便,利于电动机的维护和修理。

3.2 定子绕组采用F级绝缘材料和防护材料,定子绕组端部固定采用特殊绑扎工艺,牢固可靠,整个定子采用真空压力浸渍F机无溶剂(VPI)处理。因此,电动机具有优良可靠的绝缘性能和防潮、抗冲击能力。

3.3 本系列电动机鼠笼转子大部分采用铸铝转子,运行可靠;鼠笼铜条转子采用先进可靠的焊接工艺,并且槽内紧固处理。

3.4 轴承有滚动轴承和滑动轴承两种型式,依电动机功率大小及转速而定,其基本防护等级为IP44.如电动机具有较高的防护等级时轴承的防护等级也随之提高。采用滚动轴承的电动机均有不停机加油和排油转置。

3.5 主接线盒为密封结构,防护等级为IP54.一般装于左侧。出线盒的进线孔可朝上、下、左、右四周转换。盒内有单独的接地端子。

3.1 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.

3.2 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.

3.3 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.

3.4 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.

3.5 The junction box is of IP54 protection grade and it is usually mounted on the motor's right side(viewed from shaft extension end.)Lt 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.
