Bodine Electric 0850ER DC Motor Speed Controller

The Bodine Electric 0850ER is a 130VDC, filtered-SCR DC motor speed controller designed to drive Bodine’s 130-volt permanent-magnet DC motors, delivering a controlled, adjustable DC feed to the armature that enables precise speed regulation across a broad speed range in industrial equipment. As a filtered SCR-based device, it converts incoming power through silicon-controlled rectifiers and then smooths the resulting DC waveform, reducing ripple and helping maintain steadier torque and more consistent speed under varying load conditions, even during gradual acceleration or deceleration. The 0850ER belongs to Bodine’s line of DC controls designed for PMDC motors and geared motors used in industrial equipment, with the common application of enabling adjustable-speed operation in machines that rely on compact, reliable 130V PMDC motors. Because it provides a defined, adjustable 0–130 VDC output for PMDC applications, the 0850ER is a suitable choice when a Bodine 130V PMDC motor requires smooth, variable speed control in autonomous or integrated machinery.
