YR Motor Introduction
- The YR series 3 phase slip ring motor is a three-phase asynchronous slip-ring motor with a wound rotor, designed for high-voltage applications. Developed on the basis of the company's long-standing and proven experience in the design and manufacture of high-voltage three-phase asynchronous motors, the YR series fully complies with the latest international standards, ensuring high reliability and advanced technical performance.
- As a slip-ring 3 phase slip ring motor, the YR series features a wound rotor structure that is particularly suited for applications requiring high starting torque with low starting current. By introducing external resistance or reactance into the rotor circuit via brushes and slip rings, the motor offers excellent starting characteristics, making it ideal for driving heavy-load equipment such as ball mills, crushers, conveyors, fans, and compressors in industries like mining, cement, metallurgy, and petrochemicals.
- In terms of efficiency, the YR series 3 phase slip ring motor typically meets Grade 2 efficiency requirements, significantly improving the customer's overall operational efficiency and reducing long-term energy consumption. The motor's robust mechanical construction ensures stable operation under harsh industrial environments, while the wound rotor design allows for speed regulation when needed, providing greater flexibility compared to standard squirrel-cage motors.
