Processing Equipment: Machine tools, mixers, crushers


This motor embodies exceptional durability and versatility within the realm of general mechanical drives. Featuring a Totally Enclosed Fan-Cooled (TEFC) structure, its aluminum alloy housing not only reduces overall unit weight but also offers excellent corrosion resistance and efficient heat dissipation. In terms of operational duty, it supports S1 continuous operation, making it the ideal drive solution for fans, pumps, compressors, and various conveyor systems operating under prolonged, heavy-load conditions.
Regarding operational quality, this motor series is engineered to effectively mitigate vibration and noise issues commonly encountered in industrial environments. Through the application of precision rotor balancing techniques and sealed bearings, it achieves an efficiency rating of up to 85.5% while maintaining minimal vibration levels—thereby significantly safeguarding the precision of downstream gear reducers and mechanical transmission components. In terms of safety and adaptability, the motor holds multi-level ingress protection certifications ranging from IP54 to IP56; furthermore, it possesses the capacity to withstand short-duration overloads, effectively preventing equipment downtime caused by momentary load fluctuations. Its modular mounting design—which allows for 4x90° rotation of the terminal box and the removal of mounting feet—grants it an exceptionally broad scope of application adaptability, demonstrating superior stability across a diverse range of equipment, from machine tool spindles in processing machinery to mixers and crushers.
