YR industrial AC motor Introduction
The YR Series (IP44) wound-rotor three-phase asynchronous motors are designed for general-purpose industrial applications, with power ratings and mounting dimensions fully aligned with international IEC standards. The ac three phase induction motor features an IP44/ IP54 enclosure protection grade, IC411 self-cooling method, and S1 continuous duty cycle(S3/S4/S6 optional), ensuring reliable long-term operation in standard industrial environments.
For frame sizes YR280~355, the industrial ac motor strictly complies with the national industry standard JB/T 7119-1993 Technical Specifications for YR Series (IP44) asynchronous three phase motor. The YR 355 frame size is an independently developed model by our company, fully meeting the internal technical specification 0×D.510.083, delivering consistent performance and quality.
The entire series of industrial ac motor adopts Class F insulation system, with a rated voltage of 380V and rated frequency of 50Hz. The stator winding is delta-connected, while the rotor winding is star-connected, ensuring stable starting performance and reliable operation. These motors are ideal for applications requiring high starting torque and smooth speed control, widely used in various industrial transmission systems.
