Four, complex attributes and composition type
4.1 This series of motors have the characteristics of large locked-rotor torque, big heat ability, and protected and reputable functionality.
4.2 This series of motors adopt a box-sort construction. The frame is welded into a box-variety with steel plates. It is mild in fat and excellent in rigidity. A protective best cover or cooler is put in on the leading of the motor to aid motor warmth dissipation, installation and maintenance.
four.3 The stator adopts an external press-in shape composition, and the stator and rotor punching sheets are punched from reduced-reduction non-oriented cold-rolled silicon steel sheets. The stator winding is manufactured of F-class insulating substance, which has strong insulation face up to voltage and anti-corona capability. The winding finishes are reliably set and tied, and are dealt with with vacuum strain impregnation solvent-free of charge paint (VPI) procedure, with superb efficiency and mechanical energy Large, powerful moisture resistance and long service life.
4.4 This series of motor rotors can adopt solid aluminum or copper bar rotors according to performance and user demands to make sure the higher commencing overall performance of the motor.
four.5 The bearing adopts two forms of rolling bearing and sliding bearing. It is determined by the power and velocity of the motor. Its safety level is IP44 or IP54. The rolling bearing is outfitted with a non-stop oil injection and drainage system, which is simple for consumers to use and maintain.
4.6 The principal junction box is put on the proper facet of the motor (seen from the extended finish of the spindle), or it can be put on the remaining side in accordance to person demands. Individual grounding terminals are presented inside of and outside the house the junction box.
4.7 According to consumer requirements, temperature measurement devices can be added to important areas this kind of as stator windings and bearings to aid on-site observation and remote checking to make certain risk-free and reliable operation of the motor.
5. Problems of use
