YD Series Pole-changing Multi-speed Three Phase Motor Features

The YD Series Pole-changing Multi-speed Three-Phase Motor is a versatile and efficient motor designed for applications requiring multiple speeds. Below are its key features:

  1. Pole-changing Functionality
    The YD series motor offers the ability to change the number of poles during operation, enabling multiple speed options. By switching between different pole configurations (e.g., 2, 4, 6, or 8 poles), the motor can operate at varying speeds, providing flexibility for applications with different operational requirements.
  2. Energy Efficiency
    These motors are designed for energy efficiency, offering reliable performance at various speeds while minimizing power consumption. The multi-speed design allows the motor to operate optimally across a range of speeds, making it suitable for both low and high-speed applications.
  3. Wide Application Range
    The YD series is used in various industries, such as fans, pumps, conveyor systems, and machinery, where different speeds are required to meet specific operational needs. Its adaptability to different speeds makes it a versatile choice for many industrial processes.
  4. Stable and Reliable Operation
    The motor is engineered for smooth and stable operation, even when switching between different pole configurations. It provides consistent torque and performance, ensuring reliability in applications where the load may change speed or require variable speed control.
  5. Simple Speed Control
    The pole-changing mechanism allows for straightforward speed control without the need for complex electronic or mechanical systems. This simplicity makes it an economical and practical solution for applications where variable speed control is necessary.

The YD Series Pole-changing Multi-speed Three-Phase Motor is an ideal choice for industrial applications that require flexibility in speed control, offering energy-efficient, stable, and reliable performance.

YD Series Pole-Changing Multi-Speed Electric Motor Technical Data

The YD series multi-speed three-phase asynchronous motor, with an IP54 protection rating, is based on the Y2 series three-phase asynchronous motor. It utilizes a method of changing the stator winding connections to alter the number of poles, allowing for dual or more speeds through single or dual windings. Our YD series motors are available in 11 frame sizes, ranging from 80 to 280.

The model code for the YD series motor consists of four parts:

  1. “YD”: This indicates that the motor is an asynchronous electric motor.
  2. The digits in the second part represent the frame’s central height (this remains the same whether the motor has a base or not).
  3. The letter in the third part denotes the frame length, with “S” for short frame, “M” for medium frame, and “L” for long frame. The number following the letter indicates the core length.
  4. The fourth part, after the hyphen, specifies the number of poles of the motor.

This coding system ensures clarity in motor specifications and helps in selecting the appropriate motor for specific industrial needs.
