AC-powered brushless DC motor drive

March 26, 2008

Trust Automation has introduced its programmable TA2230 constant velocity drive, 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.

The drive is designed for new and existing industrial applications such as factory automation, machine tools, conveyors, injection molding machines, air compressors, pumps, and in existing applications where improved performance and lower operating costs are desired.

Motor output from the drive with an AC supply of 100-220 VAC at 50/60 Hz, 25 Amp peak current is the equivalent of a 15,000 Watt (45 Amp peak) PWM drive. Features include three speed setting options: 1 - (Ext) external speed command via off-board 10K potentiometer; 2 - (Int) on-board potentiometer for convenient fixed speed adjustment; and 3 - (Soft) fixed speed set via software; as well as soft start control, integral AC line filtering and self-contained, enclosed and optically isolated user interface for safety.
