4, specialized attributes and framework kind
4.one This collection of motors adopts a box composition, the body is welded from steel plates into a box shape, light-weight fat, and great rigidity. A protecting leading include or cooler is put in on the top of the motor to facilitate the heat dissipation, installation and routine maintenance of the motor.
4.two The stator adopts an external press-suit construction, and the stator and rotor are punched from low-reduction non-oriented cold-rolled silicon metal sheets. The stator winding is created of F-class insulation substance, which has powerful insulation stand up to voltage and anti-corona ability. The winding ends are reliably fixed and tied, and are dealt with with vacuum pressure impregnation solvent-cost-free paint (VPI) procedure, so the motor insulation functionality Excellent and reputable, substantial mechanical toughness, powerful humidity resistance and long provider lifestyle.
4.3 The rotor cage bar can be produced of cast aluminum or copper in accordance to efficiency parameters or user requirements. Amid them, the solid aluminum cage bar and the stop ring are integrally forged by centrifugal to make certain the mechanical power and prevent the cage bar from breaking for the duration of the motor operation the copper bar rotor is created of large-good quality copper substance, and the cage bar is welded with the conclude ring by intermediate frequency welding. The welding high quality is great. High toughness, and by means of the fastening approach in the groove, drastically decrease the phenomenon of damaged copper bars.
4.four The bearing adopts two forms of rolling bearing and sliding bearing. It is decided by the electricity and velocity of the motor. Its defense degree is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-stop oil injection and drainage device, which is easy for customers to use and maintain.
4.5 The principal junction box is positioned on the proper facet of the motor (seen from the extension finish of the main shaft), or it can be placed on the remaining aspect according to user demands. Independent ground terminals are supplied within and exterior the junction box.
four.six According to user demands, temperature measurement units can be additional to essential components this sort of as stator windings and bearings to facilitate on-site observation and remote checking to make sure safe and reliable procedure of the motor.
5. Problems of use
five.1 Ambient air temperature: -fifteen ºC~40ºC
5.two Altitude: not much more than 1000m
five.three Rated frequency: 50HZ, allowable frequency deviation ±2%
5.four During rated operation, the allowable voltage deviation is ±5%. (It can run at ±10% underneath the situations of seven.three in GB 755)
