YD Series Multi-Speed Motor
Typical applications include machine tools, textile machinery, mining and metallurgical equipment, and agricultural machinery. Selecting different speed settings helps match the motor’s operating characteristics to the equipment’s requirements.
Select the motor according to the required speed combination, output at each speed, electrical supply, operating duty, and mounting arrangement. Power, current, efficiency, and starting performance may differ between speed settings and should be checked individually.
For replacement projects, verify shaft dimensions, mounting interfaces, overall size, and the existing control system. Follow the wiring diagram supplied for the selected motor and use a suitable switching arrangement for its multi-speed configuration.

Provide the required speeds, output at each speed, voltage, frequency, mounting arrangement, and operating duty. Include load details and any requirements for switching between speeds.
It changes speed by switching winding connections to obtain different pole configurations. The available speeds are fixed steps determined by the selected model.
The catalog includes two-, three-, and four-speed configurations. Available pole combinations and output ratings depend on the model and should be confirmed before ordering.
Not necessarily. Output power, current, efficiency, and torque characteristics can differ between speed settings. Check the ratings for each operating speed.
Compatibility requires checking the ratings at each speed, shaft dimensions, mounting interfaces, overall size, and control wiring. Matching frame size or power alone does not confirm suitability.
