Induction motor – General Purpose
Our General Purpose Induction Motors include the ML and MS series, both engineered with advanced technology, premium materials, and full compliance with IEC and NEMA standards. Designed for dependable performance and long service life, these motors combine compact design with outstanding mechanical and electrical characteristics, capable of operating with dual voltages (low and high) and dual frequencies (50 Hz and 60 Hz).
The ML series single-phase dual-capacitor asynchronous motors and the MS series three-phase asynchronous motors both feature aluminum housings in TEFC configuration that ensure lightweight construction, efficient heat dissipation, and corrosion resistance. They deliver excellent performance, safety, and reliability, operating with low noise, minimal vibration, and smooth torque output.
The ML series offers starting torque up to 2.5 times the rated torque, making it ideal for heavy-load start-up applications such as air compressors, pumps, and other small machinery. The MS series provides stable and efficient operation for continuous-duty and general-purpose industrial drives.
With customizable endbells, shafts, and removable feet, both series are adaptable to diverse installation requirements in NEMA and IEC Frame. The combination of robust construction, efficient design, and quiet operation makes the ML and MS series induction motors a versatile, durable, and cost-effective solution for a wide range of industrial and commercial applications.
