ip23 motor YR-280S-4-110KW-380V-IP23-B3 with wound rotor

•YR Series (IP23) is a modern general purpose wound rotor induction motor designed as a new generation product. Their power and installation dimensions comply with IEC standards, and the℃of protection IP23 and the cooling method IC01 allow the motors to be used in clean rooms without aggressive or explosive atmospheres. An important advantage of this series is the ability to provide high starting torque at low starting current, as well as the ability to adjust the speed within a certain range.

•The motors are ideal for applications requiring high starting torque such as compressors, hoists, textile machines and conveyor belts. Due to their high efficiency and low noise level, they are widely used in conditions of frequent starts and where limited speed control is required. The design of the motors complies with the enterprise standard OXD.511.16, and the non-lifting brush system and IMB3 design ensure ease of installation and operation.

•Specifications include Class B insulation, 380V rated voltage and 50Hz frequency. The engines are designed to operate at altitudes up to 1000 m with ambient temperatures from -15℃to +40 degree. A critical requirement is the use of a starting rheostat in the rotor circuit, since direct starting with a shorted rotor winding is not permitted.
