LeTourneau Power Systems’ Switched Reluctance (SR) drive systems, consisting of motors and controls, are proven to deliver reliable, high-torque performance in even the most demanding heavy equipment applications. Remarkably simple in its design, the SR drive system has established new standards for performance, long life, reliability, and ease of maintenance.
The system consists of a brushless switched reluctance motor combined with high-power semiconductor switches and digital controls. The SR motor includes a rotor with no magnets or windings and a stator with poles containing a winding, similar to a field of a DC motor. The SR system employs the principle of magnetic attraction to move the motor’s rotor from pole to pole, creating rotation.
