ABB offers the full range of Baldor-Reliance NEMA-frame DC motors from permanent magnet designs through 5 HP and wound field designs through 500 HP. Baldor-Reliance DC motors are designed for adjustable speed operation from SCR controls. Typical applications include conveyors, extruders, winders, printing presses and metering pumps. Most designs are constructed to allow a tachometer to be added for closed-loop applications. Permanent magnet and wound field designs for 90 or 180 VDC have a 20:1 constant torque speed range.
