Features and use
The base of this series of motors adopts a thin steel plate polygonal laminated structure, which has the advantages of small volume and light weight. Suitable for thyristor rectifier power supply, under load current
Under rapid changes, the motor has good commutation performance. The entire stator and rotor are treated with solvent-free paint vacuum pressure impregnation (VPl), which gives the winding good moisture resistance and mechanical strength, as well as insulation and thermal conductivity, with excellent performance. The armature core is made of stacked silicon steel sheets and has good magnetic conductivity. All motors in this series adopt rolling bearings and a non-stop refueling structure. The insulation level of this series of motors is F level, and H level can also be produced
The installation type of this series of motors complies with GB997 and IEC34-7 "Motor Structure and Installation Type Code".
