AC Drives: Choose a drive category below for a quick summary of the series
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.

Advantages of AC Drives
- Save energy - Significant energy savings can be realized in many fan and pump applications that previously used dampers or ON/OFF control: AC drives allow motor speed to be fine-tuned to the process.
- Reduce start up current - controlling the inrush current at motor start-up allows the use of smaller fuses, and reduces electrical peak load.
- Reduce mechanical stress - controlled/smooth starting and stopping minimize mechanical shock and wear and tear on the system.
- Power factor - Motors have very poor power factors (especially at light loading). Drives significantly increase power factor (even at light loading) and can eliminate the need for power factor correction capacitors and/or utility power factor charges.
- Variable Speed and integrated functionality - AC drives can vary motor speed and direction by operator input (keypad buttons/speed control knob) or by digital and analog inputs (from pushbuttons/switches/pots or PLC outputs). Basic machine control can sometimes be performed in the drive (limit switches/sensors can be wired to the drive's inputs to control motor speed or direction).
