Brushless-Motor Driver Serves Constant-Velocity Applications
Using Hall sensors for feedback, Trust Automation's TA223 brushless-motor drive can be programmed to ramp up at a preset rate and maintain a constant velocity regardless of changes in load. The RS232-capable 9.3" × 3.5" × 5.7" driver can be set via an off- or on-board 10K potentiometer, or via software and has features such as soft start control, integral AC line filtering, enable input level, fault output level, coast input level, target velocity, Hall active level, and Current limit.
Motor output from the drive with an AC supply of 100-220 VAC at 50/60 Hz with a 25-A peak current is the equivalent of a 15,000-W (45-A peak) PWM drive. The DC voltage is 0 to 330 VDC at 45A peak and 20A RMS continuous.
