- Product Description
Slip Ring Rotor Induction Motor - High Performance YRQ Series
Our slip ring rotor induction motor delivers exceptional starting performance and overload capacity. With more than 20 years of experience, XCMOTOR offers high-end YRQ series motors intended for harsh industrial settings. Heavy machinery operates smoothly thanks to its sturdy motor technology, which also maintains exceptional controllability during the beginning procedure.
Description
In industrial drive systems, the YRQ series wound-rotor motor is an example of innovative engineering. This motor differs from traditional squirrel-cage designs in that it has exterior rotor windings that are linked via slip rings. Applications needing high beginning torque with limited starting current are best suited for this design as it provides tight control over starting characteristics.
Your operations benefit from superior starting performance with current control at just 2-3 times rated values. Meanwhile, starting torque reaches impressive 1.8-2.5 times rated torque, ensuring reliable startup even under heavy loads.
