DC Shunt Wound SCR Drive

DC Shunt Wound SCR Drive is the choice when your application requires adjustable field control, tunable speed-torque characteristics and stable operation across changing loads, all while maintaining simple SCR drive architecture.

Precise speed control. Tunable performance. Proven reliability.

ABB Baldor-Reliance DC shunt wound SCR drive motors are engineered for applications that demand adjustable speed, stable torque and fine performance tuning using SCR control. With a wound field design, these motors allow field adjustment for consistent speed regulation under varying loads—capabilities fixed-field permanent magnet motors simply can’t provide.

 

Designed for use with NEMA Type K SCR controls, this platform delivers dependable, easy-to-integrate DC performance in compact OEM machinery and industrial equipment.
