AC Motor Speed Control

Dec. 18, 2014

Bodine Electric Company’s newest AC motor speed control is simple to set up and to operate, and it features an extremely rugged NEMA-4X / IP-65 enclosure. The control is ideal for stand-alone AC gearmotor applications that require variable speed, controlled acceleration and reversing. Typical applications include conveyor systems, packaging machines, food processing equipment, medical or lab equipment and a wide range of other industrial automation equipment.

The model 2999 Pacesetter™ AC speed control is designed to drive 230 VAC, 50 or 60 Hz, inverter-duty, 3-phase gearmotors and motors that are rated up to 1 HP (746 Watts). It operates from a single-phase, 115 or 230 VAC line, and is housed in a NEMA-4X / IP-65 washdown and watertight aluminum die-cast enclosure. The control’s sine wave coded Pulse Width Modulated (PWM) output provides high motor efficiency and low noise. Linear acceleration and deceleration can be adjusted, making the control suitable for soft-start applications.

Easy to install and operate 

Bodine?s model 2999 features a built-in Forward-Stop-Reverse switch, allowing dynamic braking for applications where the motor needs to be manually or infrequently reversed. User-friendly trimpots eliminate computer-like programming, and jumpers allow the drive to be used with a wide range of motors without recalibration. The control is factory-set for most applications and is GFCI compatible.


The speed control allows for up to 200% starting torque, ensuring startup of high frictional loads. In addition, slip compensation with static auto-tune and boost circuitry provides excellent load regulation over a wide speed range. A run/fault relay signals if the drive is in stop mode, or a fault has occurred, and can turn the equipment off. Further system protection is provided by undervoltage and overvoltage circuitry, which shuts down the drive if the AC line input voltage goes above or below the operating range. Two built-in diagnostic LEDs mounted on the enclosure cover indicate “power on” and “drive status”. The control also includes a start/stop switch and a main speed potentiometer.
