The ventilation and cooling method of this series of motors can be selected by the user. It can be made into open type natural ventilation cooling, the cooling method is IC01, and it can also be made into a fully enclosed duct ventilation and cooling method, the cooling method is IC21; it is also closed air-water cooling, and the cooling method is IC86W , IPOO, IP23, IP44 or IP54. The motor is composed of stator, rotor, bearing, collector ring (slip ring) and other components. It can be made into a box type or a traditional round frame with a base plate structure. .
The stator core is made of low-loss cold-rolled silicon steel sheets superimposed and pressed, and the core section has radial ventilation ditch to improve the cooling cycle inside the motor. The stator winding adopts the formed double-stacked short-distance coil to improve the magnetic potential harmonic, and adopts the frequency conversion anti-electric insulating material and structure, and the ends are reliably fixed and bound. , and adopts the vacuum pressure impregnation solvent-free paint process (VPI), so that the stator wire diagram and the iron core become a solid whole, which has the characteristics of excellent and reliable insulation performance, high mechanical strength and strong moisture resistance.
The rotor winding is made of magnetic grade coils with heat dissipation turns. Each magnetic pole wire is welded and formed by flat copper wire. The connection with the rotating shaft adopts dove tail or T tail. Fully damped windings are used.
Sliding bearings are used, usually end cap bearings, and seat type bearings can be used. No matter what kind of structure, it has spherical self-aligning function. The sliding bearing structure adopts insulating bearings, and there is a grounding brush at the shaft extension end. The motor usually cannot bear the external axial force, and the allowable axial momentum is ±0.5-±2rnm, and the end cover type rolling bearing structure can be used.
Excitation mode of this series: generally static thyristor excitation device, other types of excitation devices are allowed.
