Why choose a DC Drive?
DC motors and drives provide several advantages and benefits over AC-powered devices:
- Inexpensive - DC drives are typically less expensive than AC drives
- Low speed performance - DC drives and motors provide excellent low speed control and stability
- Low speed power - DC motors provide exceptional low speed torque and power
- Simple - our DC drives are typically configured with potentiometers - no parameters or programming needed
