- Product Description
YR Series 3 Phase Industrial Motor — Wound Rotor Design for Heavy Industrial Applications
Sourcing the right 3 phase industrial motor for high-load environments means looking beyond rated power. The YR series covers 55–355 kW at 380V±5%, uses a wound rotor design for flexible speed and torque control, and is available in IP23 or IP54 protection levels. Bearing options include SKF, NSK, and FAG. Products comply with IEC standards and carry CCC, CE, ISO9001, CQC, CRCC, UL, and GOST certifications.

The wound rotor design gives more control over starting torque and speed compared to squirrel cage types — useful in applications where load varies or soft-start characteristics matter. The low-noise structure and relatively light body reduce installation complexity. IEC-compliant installation dimensions mean the YR series fits most existing equipment frames without structural modification.
Common Application Problems and How the YR Series Addresses Them
Continuous-load environments expose motors to heat buildup, vibration, and premature bearing wear. These directly affect uptime and maintenance costs.
Common Issue | YR Series Characteristic |
Excessive heat under sustained load | High-efficiency design reduces energy dissipation |
High vibration and noise | Low-vibration structure with precision bearings |
Bearing maintenance causing downtime | IP54 configuration supports lubrication without stopping the machine |
Short service life under heavy cycling | Wound rotor design with reliable insulation system |
Limited bearing sourcing options | Compatible with SKF, NSK, and FAG on request |
Industry Applications
The YR series 3 phase industrial motor is used across a range of heavy industrial machinery.
· Ventilators and compressors — handles continuous load with stable torque output
· Water pumps — consistent performance across variable flow conditions
· Crushers — wound rotor design absorbs mechanical shock loads at startup
