4, technical characteristics and framework variety
four.one This series of motors adopt a box-sort construction. The frame is welded from metal plates into a box-kind, with robust ribs and good strength. The
motor is equipped with a protecting include or cooler to aid the motor’s warmth dissipation, set up and maintenance.
four.2 The stator adopts an external push-fit structure, and the stator and rotor are punched from lower-reduction non-oriented chilly-rolled silicon metal sheets. The stator winding is manufactured of F-class insulation substance, which has robust insulation stand up to voltage and anti-corona capacity. The winding ends are reliably fixed and tied, and vacuum stress impregnation solvent-totally free paint procedure (VPI) is utilised, so the motor’s insulation efficiency Exceptional and trustworthy, high mechanical power, powerful humidity resistance and prolonged services existence.
4.3 The rotor cage bar can be created of forged aluminum or copper in accordance to functionality parameters or consumer demands. Amongst them, the solid aluminum cage bar and the stop ring are integrally cast by centrifugal to ensure the mechanical toughness and stop the cage bar from breaking throughout the motor procedure the copper bar rotor is manufactured of large-top quality copper material, and the cage bar is welded with the finish ring by intermediate frequency welding. The welding top quality is good. High strength, and by way of the fastening process in the groove, drastically minimize the phenomenon of damaged copper bars.
4.4 When the motor has no axial thrust, the bearing adopts rolling bearing, and its defense grade is IP23IP44, IP54 or IP55. The rolling bearing is geared up with non-stop oil injection and drainage unit, which is easy for customers to use and keep. When bearing axial thrust, thrust sliding bearing can be used.
4.five In accordance to consumer requirements, temperature measurement products can be added to important parts such as stator windings and bearings to aid on-web site observation and distant checking to make sure risk-free and reliable procedure of the motor.
