Your Challenge: Equipment requires frequent speed adjustments but lacks flexible control options.

Our Solution: Our motors support wide-range speed regulation through rotor series resistance, eliminating the need for expensive variable frequency drives in many applications.

Your Challenge: Unpredictable maintenance schedules disrupt production timelines.

Our Solution: Premium SKF, NSK, and FAG bearings (customizable per request) extend service intervals. IP23 and IP54 protection levels safeguard internal components against harsh environments.

Technical Advantages

The YR series motors incorporate several engineering innovations that enhance value:

· Modular design simplifies maintenance and reduces downtime costs

· Class F insulation provides superior heat resistance and extended operational life

· Optimized wound rotor configuration enables soft-start capabilities for heavy-load equipment

· Low vibration and noise characteristics improve workplace safety and comfort

· Energy-efficient operation cuts electricity consumption by up to 6% compared to standard motors

These features directly impact your total cost of ownership, making the initial three phase asynchronous motor price investment more economical over the motor's lifecycle.

FAQ

Q: What is the core advantage of YR series wound rotor motor compared with squirrel-cage Y motor?

A: The YR motor adopts wound rotor + slip ring structure. It can connect external starting rheostat to rotor circuit, delivering large starting torque with low starting current, which greatly reduces impact on power grid. It also supports wide-range speed regulation via rotor series resistance, making it ideal for heavy-load startup equipment like ball mills, crushers, hoists, and compressors. Squirrel-cage motors cannot realize soft heavy startup or simple speed adjustment.

Q: Can we short-circuit the rotor winding directly to start the motor without starting resistance?

A: Strictly prohibited. Direct short-circuit startup will generate huge rotor current, cause severe overheating of rotor winding, burn slip ring and carbon brushes instantly, and trigger grid voltage drop. Standard operation requires matching three-phase starting resistance box connected to slip rings before power-on, then gradually cutting resistance as speed rises.

Q: Is slight sparking on slip ring normal during operation? How to eliminate severe sparks?

A: Tiny, uniform dot sparks (Grade 1) are normal friction discharge between carbon brush and slip ring. Heavy arc/spark with black burning marks belongs to abnormal fault. Causes and solutions include: carbon brush wear or insufficient spring pressure—replace brushes and adjust spring tension; slip ring surface oxidation or oil stains—polish with fine abrasive cloth and clean grease; unbalanced rotor three-phase resistance—inspect rotor winding for open circuit or loose welding points.

Q: Can YR motor adjust speed continuously? What are the pros and cons of resistance speed regulation?

A: Yes, stepless speed change within a certain range by changing rotor series resistance. Advantages include low initial investment, simple control cabinet structure, and easy maintenance. Disadvantages are extra energy loss converted into heat on resistance and low operation efficiency—only suitable for short-time variable-speed working conditions. For long-term high-efficiency speed regulation, cascade speed control or high-power inverter schemes are recommended.

Q: What common faults lead to low speed and weak torque after startup?

A: Main root causes include rotor circuit faults (loose brush contact, broken rotor wire, unbalanced starting resistance), power supply issues (three-phase voltage unbalanced or voltage too low), mechanical problems (motor overload, bearing jamming, transmission stuck), and wrong wiring (stator delta connection mistakenly wired as star connection). Troubleshooting sequence: check slip ring and brushes → test three-phase rotor DC resistance → measure input voltage → inspect mechanical load.
