STANDARD FEATURES
- The stock models in this BLDC Control series with 115VAC input will be phased out and obsoleted soon, and are no longer available for new applications. Consider one of our inverter-duty AC gearmotor and control systems as a viable alternative.
- If you require a BLDC control for one of our 130VDC BLDC motors or gearmotors, please contact “American Control Electronics” for drop-in control options.
- Operates from 115 Volt AC line.
- Filtered DC output results in cooler operation of the motor.
- Unique Smart Reverse™ circuit for remote control of motor direction.
- Dynamic braking for quicker stops.
- 12 pulse/revolution tach output provides indication of motor speed.
- Green LED indicates AC power on.
- Red LED indicates control shutdown due to a fault condition.
- Speed can be adjusted manually with a remote 10K ohm potentiometer (included).
- DIP switches set the current limit so that the same control model can drive any size Bodine motor.
- Five onboard user-adjustable pots for torque limit, minimum speed limit, maximum speed limit, acceleration time, and deceleration time.
- Fuse holders for line and motor fuses (fuses included).
- Inherent closed loop system maintains a 1% maximum change in motor speed from 0 - 100% of rated load when operated at rated speed.
Application Information
- Extended 2-year system warranty when a Bodine gearmotor/motor and control are purchased together.
- Rated for 50° C ambient.
- Intended to be mounted in separate enclosure supplied by user.
- Drives 130V Bodine Brushless DC Motors.
- Screw terminal block for line and motor connections.
- Plug-in connector for commutation connections.
- Model 3911 for 2500 rpm motors.
- Model 3921 for 10,000 rpm motors.
- The maximum recommended distance between the control and the motor should not exceed 12 ft. (3.5 m).
