A Reluctance Motor

A Reluctance Motor

The reluctance motor can operate continuously in environments up to 180°C, maintaining an efficiency of 88%~92%. Through precise design of the rotor slot shape and flux path via FEA, flux utilization is increased by approximately 40%, allowing for higher torque output within the same volume.

ARL Series Switched Reluctance Motors for Textile Machinery​

 

The ARL series switched reluctance motor drive system, leveraging its unique structure and control principles, delivers a starting torque up to five times the rated torque. When applied in textile machinery, it simplifies the transmission chain, enables direct drive, enhances weaving processes, and reduces energy consumption.

 

Key Functions

 

When integrated into textile machinery, the switched reluctance motor drive system enables direct drive, eliminating marks caused by loom start-stop cycles and avoiding the "dense-sparse fabric" phenomenon during loom operation. Additionally, it supports enhanced weaving processes such as variable-speed weaving.

 

Technical Features

 

  • Eliminates traditional clutches; the motor is directly connected to the spindle, shortening the transmission chain and significantly improving overall energy efficiency.
  • Operates at low speeds to perform functions like weft-finding and reverse driving without requiring a separate weft-finding motor.
  • Fast dynamic response facilitates easy implementation of variable-speed weaving, optimizing loom performance.
  • Rich controller interfaces enable seamless integration with main controls of different looms, enhancing versatility.
  • Supports resolver and various encoder interfaces for high-precision or specialized application control.
  • Simplifies loom mechanical structure, reducing post-maintenance requirements.
