High Efficiency Multi-Speed Three Phase Induction Motor with Cast Iron/Aluminum Shell

The multi-speed series three-phase asynchronous motors are designed for industrial applications requiring variable speed operation. These motors comply with IEC 60034 standards and are available in both cast-iron and aluminum-shell configurations.

By modifying the motor winding data and utilizing different wiring methods, the same motor unit can achieve multiple rotational speeds. The motor windings come in two configurations: single-winding and double-winding designs, allowing users to select optimal speeds for different operational requirements.

These energy-efficient motors are widely used in various industrial applications including machine tools, mining equipment, metallurgical machinery, and textile manufacturing. They are particularly suitable for universal, combined, and special-purpose metal-cutting machine tools, as well as other transmission mechanisms requiring speed variation.

The motors feature robust construction with options for different protection classes (IP54 to IP66) and cooling methods (IC411, IC410). They are designed for reliable operation in ambient temperatures ranging from -10°C to 40°C and altitudes up to 1000m.
