Phase Wound Induction Motor

Shenyang Electric Machine Manufacturing Co., Ltd. is one of the leading manufacturers and suppliers of phase wound induction motor in China. As we have world-leading production equipment and strong manufacturing capabilities, we warmly welcome you to buy premium phase wound induction motor at competitive price from our factory. Also, quotation is available.

 

Manufactured to IEC 60034 international standards, the phase-wound induction motor is fitted with three-phase symmetrical distributed rotor windings. A slip-ring and carbon-brush assembly forms the electrical link between the static external control circuit and rotating rotor winding. Connected with external resistors or liquid rheostats, the motor achieves restrained starting current and boosted starting torque. Once startup completes, the rotor windings can be short-circuited for high-efficiency operation.

• Core Lamination Process: Cold-rolled silicon steel sheets are punched, stacked and clamped with high-precision tooling. Inter-sheet insulating coating is kept intact during lamination to reduce eddy-current loss and no-load loss.
• Winding & Insulation Process: High-purity copper conductors are wound into standardized coils. Coils are embedded into stator and rotor slots with careful shaping.
• Slip-ring Processing: Copper alloy forgings undergo turning, grinding and surface finishing. Dynamic balance test is carried out after assembling slip-ring onto shaft to lower vibration during high-speed rotation.
• Rotor Assembly & Dynamic Balance: After rotor winding installation, rotor core assembly is subjected to two-stage dynamic balance calibration to minimize residual unbalance value, cutting running vibration and noise.
• Frame Post-processing: Cast iron frame goes through stress-relief annealing treatment before machining, reducing internal stress deformation caused by long-term vibration.
• Final Complete-machine Test: Each finished motor goes through winding resistance test, insulation resistance test, no-load running test and high-voltage withstand test before delivery.

 

 

The production line covers full frame range for phase wound induction motor. Frame sizes range from H355 up to H1120, power scope covers 185kW to several megawatts. We possess complete in-house processing capacity including silicon-steel sheet stamping, coil winding, VPI impregnation treatment, rotor assembly and complete-machine assembling. Key processing equipment ensures stable batch quality. Production workshop supports both standard mass production and non-standard customized modification for special working-condition requirements. Strict production scheduling enables steady monthly output of heavy-duty large-size motors.
