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.

Great experience overall with this purchase. The delivery was incredibly fast and well-handled, arriving ahead of schedule without any delays or damages. Good packaging ensured everything was secure upon arrival. The quality of the motor appears excellent, with a sturdy build and no visible defects. Service from the seller was top-notch; they were responsive and helpful throughout the process. Generally, I'm very satisfied and would recommend this to others based on these aspects.
Absolutely impressed with the shipping speed—it arrived much sooner than anticipated. The packaging was secure and well-protected, ensuring no damage during transit. As for quality, the motor feels robust and well-constructed, with a solid finish that suggests durability. Customer service was responsive and helpful when I had a query about the delivery timeline. Overall, a smooth and satisfactory experience from order to receipt.
