Pain Points vs. Solutions

Your Challenges:

· High starting current causes grid instability during equipment startup

· Dust and moisture ingress leads to frequent insulation failures

· Limited torque control makes heavy-load starting difficult

· High maintenance costs due to complex disassembly procedures

Our Solutions:

· Wound rotor structure reduces starting current to 2-3× rated current (versus 5-7× for squirrel-cage types)

· IP54 protection grade effectively blocks dust, water vapor, and solid particles

· External resistance adjustment enables starting torque of 1.8-2.5× rated torque

· Externally mounted slip rings and brushes simplify maintenance without full disassembly

Technical Advantages

Our motors include a number of unique advantages:

Better Starting Performance : The wound rotor type has slip rings that link to external starting resistors which allow more flexible control of current and torque at startup without perturbing your power grid.

Improved Environment Protection: IP54 sealing prevents polluted air from reaching the stator windings, decreasing insulation breakdown due to collection of dust significantly.

Independent Cooling System: The air-to-air cooling design is not influenced by the atmosphere, therefore assuring steady performance even in workplaces with high temperatures.

Sealed Slip Ring Chamber: Independent sealing prevents carbon particles from entering the main motor chamber, which protects the winding integrity and extends the service life.

Precision Components: SKF, NSK & FAG bearings are available as per your demand to provide smooth running with minimum vibration & noise.
