4, technological characteristics and framework variety
4.1 This series of motors adopts a box composition, the body is welded from metal plates into a box condition, light weight, and excellent rigidity. A protective leading include or cooler is installed on the prime of the motor to aid the heat dissipation, installation and upkeep of the motor.
four.two The stator adopts an external push-match construction, and the stator and rotor are punched from minimal-reduction non-oriented chilly-rolled silicon steel sheets. The stator winding is produced of F-course insulation materials, which has sturdy insulation endure voltage and anti-corona potential. The winding finishes are reliably fixed and tied, and are dealt with with vacuum pressure impregnation solvent-free paint (VPI) procedure, so the motor insulation functionality Outstanding and reputable, substantial mechanical toughness, sturdy moisture resistance and prolonged service life.
4.3 The rotor cage bar can be manufactured of forged aluminum or copper according to functionality parameters or user needs. Among them, the solid aluminum cage bar and the conclude ring are integrally forged by centrifugal to ensure the mechanical toughness and avoid the cage bar from breaking for the duration of the motor procedure the copper bar rotor is created of substantial-quality copper materials, and the cage bar is welded with the stop ring by intermediate frequency welding. The welding high quality is good. Higher energy, and via the fastening process in the groove, drastically lessen the phenomenon of broken copper bars.
four.four The bearing adopts two varieties of rolling bearing and sliding bearing. It is determined by the electricity and pace of the motor. Its safety stage is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-quit oil injection and drainage device, which is effortless for consumers to use and maintain.
four.5 The primary junction box is placed on the appropriate aspect of the motor (seen from the extension conclude of the primary shaft), or it can be put on the left side in accordance to user demands. Separate ground terminals are provided within and outdoors the junction box.
4.six According to consumer requirements, temperature measurement units can be extra to critical parts this kind of as stator windings and bearings to facilitate on-internet site observation and distant monitoring to make certain secure and reputable procedure of the motor.
