Slip ring induction motor YR-280S-4-55KW-380V-IP44

Electric motor with a wound rotor YR-280S-4 - low-voltage three-phase asynchronous unit. Has case size 280S, 4 poles, rated power 55 kW, voltage 380 V and frequency 50 Hz, protection class IP44, made according to the installation design IMB3 (horizontal installation). Equipped with a wound rotor, supports soft starting and speed regulation through external resistance; The stator winding is treated with impregnation, providing stable insulation. The housing protects from dust and splashes of water, longitudinal ventilation guarantees effective heat transfer; The commutator and brushes have reliable contact, ensuring operation with low noise and vibration levels.

The YR-280S-4 electric motor has three key advantages: powerful starting under heavy loads, flexible speed control and improved protection class. The combination of 55 kW power and 4 poles provides high starting torque with low starting current, eliminating the load on the electrical network. Protection class IP44 compared to basic IP23 allows you to work in conditions of increased dust and light humidity; IMB3 version provides wide compatibility with equipment. Connecting an external resistance ensures smooth speed control, ideal for driving conveyors, mixers and other heavy equipment, characterized by stable operation and easy maintenance.
