Product catalog summary
Overview: The document describes the WPM filtered control, a pulse width modulated (PWM) control designed for PMDC gearmotors and motors. It offers smooth speed control, high torque, and lower motor operating temperatures, housed in a NEMA 1/IP-20 enclosure.
Specifications:
  • Input: 115 VAC, 50/60 Hz, 1-phase
  • Output Voltage: 0-130 VDC
  • Filtered DC Output: Ensures cooler motor operation, longer brush life, lower audible noise, and a wider speed range
  • Inhibit Function: Optional user-supplied inhibit switch connections available
  • Forward-Brake-Reverse (FBR) Switch: Provides dynamic braking and direction control
  • Diagnostic LEDs: Indicate power status and current output limit
  • User-Adjustable Pots: Include TORQ (current) limit, MIN/MAX speed limits, ACC (acceleration/deceleration time), and REG (IR compensation)
  • Power Cord: 6-foot with North American 3-prong connector
Applications: Suitable for bi-directional applications such as conveyors, packaging machines, screen printing equipment, conveyor ovens, medical devices, lab instrumentation, and labeling equipment.
Compliance: RoHS compliant.
Motor Specifications:
  • Motor HP Rating: 7/16 @ 90 V, 5/8 @ 130 V
  • Control Input Voltage: 115 VAC
  • Motor Rating: 90 or 130 VDC
  • Continuous Output Current: 3.7 Amps
  • Peak Output Current: 7.1 Amps
Additional Information: Bodine offers over 1,200 standard gearmotors, motors, and system-matched speed controls. For more details, specifications, and CAD drawings, visit their website.
Dimensions and Connections: The document includes detailed dimensions and connection instructions, emphasizing the use of shielded cables and suggesting a motor fuse rated at 1.2x the motor rating.

WPM - Filtered DC Motor Speed Control with Dynamic Braking-1

Speed and Direction Control for 90 or 130 VDC PMDC Gearmotors and Motors The type WPM filtered control provides smooth speed control for PMDC gearmotors and motors. The WPM is a pulse width modulated (PWM) control that provides high torque and lower motor operating temperatures. It is housed in a NEMA 1/IP-20 enclosure. The Forward-Brake-Reverse switch provides dynamic braking for applications where the motor needs to be manually infrequently reversed, or as a setup function in an application. Simple trim pot adjustments eliminate the computer-like programming required in other drives. DIP switches allow the control to be easily calibrated for different size motors. • Input: 115 VAC, 50/60 Hz, 1-phase • Output Voltage: 0-130 VDC • iltered DC Output: for cooler motor operation, F longer brush life, lower audible noise, and wider speed range • nhibit Function: connections for optional I user-supplied inhibit switch available • orward-Brake-Reverse (FBR) Switch F for Dynamic Braking: reverse direction after gearmotor/motor comes to a full stop Typical Applications • wo Diagnostic LEDs: indicate when power is T on and when current output is at limit set by TORQ pot • ser-Adjustable Pots: U TORQ (current) limit–protects system from sustained overloads MIN speed limit–sets minimum speed MAX speed limit–sets maximum speed ACC–sets acceleration/deceleration time REG–adjusts IR compensation • ower Cord: included, 6-foot with P North American 3-prong connector RoHS COMPLIANT Continuous Output Current (Amps) Ideal for use in bi-directional applications such as conveyors, packaging machines, screen printing equipment, conveyor ovens (food processing applications), medical devices, lab instrumentation and labeling equipment.
