Four, complex characteristics and framework kind
four.one This sequence of motors adopts a box construction, the frame is welded from steel plates into a box shape, mild excess weight, and good rigidity. A protecting best cover or cooler is set up on the prime of the motor to aid the heat dissipation, set up and maintenance of the motor.
4.two The stator adopts an external press-match composition, and the stator and rotor are punched from minimal-reduction non-oriented chilly-rolled silicon steel sheets. The stator winding is manufactured of F-class insulation material, which has powerful insulation withstand voltage and anti-corona capability. The winding ends are reliably fixed and tied, and are handled with vacuum force impregnation solvent-totally free paint (VPI) process, so the motor insulation overall performance Exceptional and reliable, high mechanical power, powerful moisture resistance and prolonged provider daily life.
four.3 The rotor cage bar can be made of cast aluminum or copper according to efficiency parameters or person requirements. Amid them, the forged aluminum cage bar and the conclude ring are integrally cast by centrifugal to make certain the mechanical strength and avoid the cage bar from breaking for the duration of the motor operation the copper bar rotor is produced of substantial-quality copper material, and the cage bar is welded with the conclude ring by intermediate frequency welding. The welding quality is excellent. Substantial energy, and via the fastening procedure in the groove, greatly decrease the phenomenon of broken copper bars.
four.four The bearing adopts two varieties of rolling bearing and sliding bearing. It is determined by the energy and pace of the motor. Its security degree is IP44, IP54 or IP55. The rolling bearing is equipped with a non-end oil injection and drainage system, which is simple for users to use and maintain.
four.5 The primary junction box is positioned on the appropriate side of the motor (considered from the extension stop of the main shaft), or it can be placed on the left aspect in accordance to user needs. Individual floor terminals are offered inside of and exterior the junction box.
4.6 According to user needs, temperature measurement products can be included to important components this sort of as stator windings and bearings to aid on-web site observation and remote monitoring to make certain secure and reliable operation of the motor.
five. Conditions of use
