Product Description

3 phase induction squirrel cage motor Manufacturer and Supplier

3 phase induction squirrel cage motor have become common for operating pumps, fans, compressors, conveyors and processing equipment in all branches of production. They operate well with a basic but clever rotor design . Instead of coiled coils they use aluminum or copper bars . This eliminates brushes and slide rings that often need to be maintained . Squirrel cage motors are very reliable and cheap to build for continuous industrial use . They have few moving components and no external electrical connections to the rotor .

Shaanxi Qihe Xicheng Electromechanical Equipment Co., Ltd. (XCMOTOR) brings over 20 years of expertise in delivering power equipment solutions. We have strong connections with 30+ top motor manufacturers like as ABB, Siemens, Wolong and XEMC. So you get only genuine parts from reputable companies.

Pain Points versus Solutions

Challenge: Routine Maintenance & Downtime

Traditional wound-rotor motors have to change brushes often and maintain the collector, which causes a production halt.

Our solution: The device has a brushless rotor design that requires no collector maintenance, decreasing unexpected downtime by up to 85%.

Challenge: Increased Energy Prices

Older motor designs are 80-85 % efficiency . A lot of electrical power is wasted as heat .

Our Solution: Our IE3-compliant motors reach 92% efficiency with power costs (usually 97% of total lifespan costs) under 4 years payback for equipment working 8+ hours per day.

Challenge: Harsh Operating Environment

Motors have a shorter life in dusty, humid or corrosive environments.

Our Solution : IP55 protection rating protects the internal components from water jets and infiltration of dust; high strength cast iron structure withstands vibration and environmental deterioration.

Advantages of 3 phase induction squirrel cage motor in technical area

Outstanding Energy Efficiency

Our motors are produced according to international efficiency requirements IE3 and hence have little loss during operation. Advanced electromagnetic design ensures the optimum flux distribution, minimum heat production and maximizes the torque output .

Better Starting Performance

Deep rotor slot design provides 200-250% beginning torque, so that smooth acceleration may be achieved under severe loading without extra starting equipment.

Longer service life

High-temperature Class F (155 °C) insulation is thermally stressed. Precision balanced rotors provide vibration-free operation. For demanding applications, premium SKF/NSK/FAG bearings may be chosen to increase maintenance intervals to more than 20,000 hours of operation.

Thermal Management

External cooling fins and improved ventilation channels effectively disperse heat and keep the operating temperature below acceptable limits even during prolonged operation cycles.

Production Process

We follow stringent norms of quality in our manufacturing:

l Material Inspection: Incoming quality checks for all electrical steel laminations, copper bars and bearings.

l Precision Winding Automated winding machines provide regular coil production and constant insulation coverage.

l Die-Cast Rotor Production: Seamless conductor bars are produced with low resistance by high-pressure aluminum injection.

l Dynamic balancing Computer controlled balancing per ISO G6.3 standards reduces residual vibration.

l Final Testing: Performance validation of each motor at no load, locked rotor and full load before shipping.

Complete traceability is possible with SAP-based factory management systems, that can follow each element from raw materials to completed goods. YE3

Industrial Applications

Material Handling: Conveyor systems, elevators, automated storage and retrieval systems are benefited by consistent, constant-speed operation.

HVAC Systems: Building management systems with centrifugal fans and pumps provides optimum air circulation with minimum energy use.

Food & Beverage: Stainless steel versions tolerate washdown situations in processing and packaging lines.

Metalworking: CNC feed drives, machine tool spindles, hydraulic power units need accurate speed control.

Textile Manufacturing : Spinning frames, looms and dyeing machines need motors that can be frequently started and reversed. application

Customization Options

Because the typical specs of the 3 phase induction squirrel cage motor are not applicable to all uses, we offer:

l Voltage Adaptation : Special windings for non-standard voltages (220V,415V,460V,690V)

l Mounting configurations: foot-mounted (B3), flange-mounted (B5, B14) or shaft-mounted versions

l Shafts: Long shafts, duples or unusual keyway shapes

l Environmental Upgrades: Tropical insulation (Class H), marine-grade coatings or explosion-proof enclosures

l Bearing Selection: High-end bearing brands requested by customers for critical applications

Brake Integration Electromagnetic brakes (like our YEJE3 series) for positioning and anti-rollback safety

FAQ

Q：What is YEJE3 electromagnetic brake motor?

A：YEJE3 series are IE3 high-efficiency three-phase aSynchronous Motors with built-in AC electromagnetic brake at the rear end. The brake locks the shaft immediately upon power cut. It integrates energy-saving performance and precise braking function, with standard voltage of 380V.

Q：Which equipment is YEJE3 electromagnetic brake motor suitable for?

A：Widely applied in small lifting hoists, stereo garages, machine tool feed mechanisms, conveyors, packaging equipment, elevator auxiliary machines, automatic assembly lines and other machinery requiring stop positioning and anti-slip protection.

Q：Why the motor runs normally but cannot brake tightly after power off?

A：Common causes include severely worn brake friction pads leading to excessive clearance, fatigued brake springs with insufficient elasticity, oil stain and dust attached on brake disc surface, or stuck brake iron core failing to rebound. Solutions: Adjust brake clearance, replace friction pads and springs, clean brake disc surface, maintain movable iron core parts.

Q：What causes the brake to make loud noise when releasing?

A：Causes include uneven brake clearance adjustment, rust and dust on iron core contact surface, lack of grease on brake bearing, or damaged friction pads. Solutions: Readjust uniform brake clearance, remove rust and dust on iron core, refill lubricating grease to rear bearing regularly, replace damaged friction pads.
