Drives

Electrical drives control the speed, torque and direction of a downstream device, most typically a motor. Variable frequency drives (VFD) provide speed control for AC motors such as those in conveyors, fans, pumps and shop tools. DC drives provide variable speed control for DC motors, ideal for applications requiring low speed control, torque and power.

DC Drives

GS1 (120 / 230 VAC V/Hz Control)

GS2 (115 / 230 / 460 / 575 VAC V/Hz Control)

DURApulse - GS3 (230 / 460 VAC Sensorless Vector Control)

DURApulse - GS4 (230 / 460 VAC Sensorless Vector w/PLC)

IronHorse® GSD Series DC Drives - 1/50 HP to 3 HP
These IronHorse DC drives can accommodate 1/50 hp @ 12VDC all the way up to 3hp @ 240VAC. DC motors and drives can provide several advantages and benefits over AC:

Inexpensive
Low speed performance
Low speed power
Simple
- our DC drives typically use potentiometers for configuration
- no parameters or programming needed
DC Drives Overview and Selection Guide

Variable Frequency AC Drives - 1/4 HP to 300 HP
AutomationDirect carries a range of AC variable frequency drives (VFD) for motor speed control and other industrial control applications.

The high quality and low prices make our GS1 series mini AC drives and GS2 series micro variable speed drives an incredible deal.
