Bodine: DC motor speed controller

Designed for use in bi-directional applications such as conveyors, packaging machines, food processing applications, medical devices, and more, Bodine’s new 0794 DC motor speed controller is housed in a NEMA 1/IP-20 enclosure, and features a Forward-Brake-Reverse switch and dynamic braking to provide smooth speed control for PMDC gearmotors and motors.

The 0794’s pulse width modulated (PWM) design is said to provide higher torque and lower motor operating temperatures than typical SCR controls. Filtered DC output to the motor allows cooler operation, longer brush life, lower audible noise, and wider speed range. The type “WPM” control accepts 115 VAC, 50/60 Hz, 1-phase input. Motor power ratings are 7/16 HP (326 Watts) at 90 VDC, or 5/8 HP (466 Watts) at 130 VDC.

This new stock model features a Forward-Brake-Reverse switch, allowing dynamic braking for applications where the motor needs to be manually and infrequently reversed, or when required as a setup function in an application. Five trim pot adjustments (TORQ limit, MIN and MAX speed, acceleration/deceleration, and IR compensation) eliminate the computer-like programming required in other drives. DIP switches allow the control to be easily calibrated for different motor sizes. Two Diagnostic LEDs on the PC board indicate when power is on and when current output is at limit set by the TORQ pot.
