Constant Velocity AC/DC Motor Drives

A compact, low cost, programmable TA2230 constant velocity drive is designed to run a brushless motor at a constant velocity using the motor's Hall sensors for the velocity feedback. Using an RS232 interface, the drive can be programmed at start-up to ramp up at a preset rate and maintain a constant velocity, regardless of changes in load.

This compact brushless motor drive measures 9.3" x 3.5" x 5.7". Motor output from the drive with an AC supply of 100V to 220V at 50/60 Hz, 25A peak current is the equivalent of a 15,000W (45A peak) PWM drive. The DC voltage is 0V to 330V at 45A peak, 20A RMS continuous. Features of the TA2230 drive include three speed setting options: (ext) external speed command via off-board 10K potentiometer; (int) on-board potentiometer for convenient fixed speed adjustment; and (soft) fixed speed set via software.
