Four, technological attributes and structure kind
four.1 This sequence of motors adopts a box structure, the frame is welded from metal plates into a box shape, light fat, and excellent rigidity. A protecting prime protect or cooler is installed on the leading of the motor to aid the warmth dissipation, set up and routine maintenance of the motor.
four.two The stator adopts an exterior press-match construction, and the stator and rotor are punched from reduced-reduction non-oriented cold-rolled silicon metal sheets. The stator winding is made of F-course insulation content, which has powerful insulation stand up to voltage and anti-corona capability. The winding finishes are reliably mounted and tied, and are dealt with with vacuum strain impregnation solvent-free of charge paint (VPI) process, so the motor insulation functionality Superb and dependable, higher mechanical energy, sturdy moisture resistance and prolonged support lifestyle.
4.three The rotor cage bar can be made of cast aluminum or copper in accordance to overall performance parameters or user needs. Amid them, the cast aluminum cage bar and the conclude ring are integrally forged by centrifugal to guarantee the mechanical energy and stop the cage bar from breaking for the duration of the motor procedure the copper bar rotor is produced of higher-good quality copper materials, and the cage bar is welded with the conclude ring by intermediate frequency welding. The welding quality is great. High energy, and by means of the fastening procedure in the groove, drastically lessen the phenomenon of broken copper bars.
4.four The bearing adopts two varieties of rolling bearing and sliding bearing. It is identified by the electricity and velocity of the motor. Its defense level is IP44, IP54 or IP55. The rolling bearing is outfitted with a non-cease oil injection and drainage gadget, which is effortless for customers to use and sustain.
4.five The main junction box is put on the right side of the motor (considered from the extension finish of the primary shaft), or it can be positioned on the still left side according to consumer specifications. Individual ground terminals are presented inside of and outdoors the junction box.
four.6 According to person specifications, temperature measurement units can be added to essential areas this sort of as stator windings and bearings to aid on-internet site observation and distant monitoring to make sure protected and dependable procedure of the motor.
5. Conditions of use
five.1 Ambient air temperature: -fifteen ºC~40ºC
five.two Altitude: not much more than 1000m
