4, technical attributes and structure type
4.1 This sequence of motors adopts a box composition, the body is welded from metal plates into a box shape, light-weight bodyweight, and great rigidity. A protective prime protect or cooler is set up on the top of the motor to aid the warmth dissipation, installation and upkeep of the motor.
four.2 The stator adopts an exterior press-fit construction, and the stator and rotor are punched from minimal-loss non-oriented chilly-rolled silicon steel sheets. The stator winding is manufactured of F-class insulation content, which has robust insulation endure voltage and anti-corona ability. The winding ends are reliably mounted and tied, and are handled with vacuum force impregnation solvent-free of charge paint (VPI) method, so the motor insulation functionality Outstanding and trustworthy, substantial mechanical energy, sturdy dampness resistance and lengthy support lifestyle.
4.3 The rotor cage bar can be produced of solid aluminum or copper in accordance to functionality parameters or person specifications. Among them, the cast aluminum cage bar and the finish ring are integrally solid by centrifugal to make certain the mechanical toughness and stop the cage bar from brea ept throughout the motor procedure the copper bar rotor is created of higher-top quality copper content, and the cage bar is welded with the conclude ring by intermediate frequency welding. The welding high quality is excellent. High strength, and via the fastening approach in the groove, significantly minimize the phenomenon of broken copper bars.
four.4 The bearing adopts two types of rolling bearing and sliding bearing. It is identified by the electricity and velocity of the motor. Its defense amount is IP44, IP54 or IP55. The rolling bearing is equipped with a non-cease oil injection and drainage device, which is effortless for consumers to use and keep.
four.5 The main junction box is placed on the proper aspect of the motor (seen from the extension finish of the major shaft), or it can be positioned on the still left side in accordance to person requirements. Independent ground terminals are provided inside and outside the junction box.
4.6 In accordance to consumer requirements, temperature measurement units can be added to important parts this sort of as stator windings and bearings to aid on-site observation and remote monitoring to make sure secure and reputable operation of the motor.
five. Circumstances of use
5.1 Ambient air temperature: -15 ºC~40ºC
5.2 Altitude: not more than 1000m
five.3 Rated frequency: 50HZ, allowable frequency deviation ±2%
five.4 During rated procedure, the allowable voltage deviation is ±5%. (It can operate at ±10% beneath the situations of 7.3 in GB 755)
