Multiple-Speed Three-Phase Marine Induction Motor
  • Introduction
  • Main Technical Data
Inquiry Form

The YD-H series is a pole-changing multi-speed three-phase induction motor used in marine machinery. These three-phase induction motors can change their poles and rotation speed depending on the load and feature high energy efficiency, large starting torque, and low noise and vibration. The cast iron enclosure and winding surface of the multi-speed marine motor is treated to be waterproof and resistant to fungus and sea spray to meet standards for machinery in humid environments.
