| DMC-500™
DC Motor Controller |
- The
DC Motor Controller 500 is a SCR motor speed controller
using an embedded micro controller to provide motor speed
regulation and torque compensation. The controller can be
used to control permanent magnet (PM) or shunt wound field
motors up to ¼ hp and is designed to be used with
the WSC-1000™ Weld Sequence Controller to control
linear DC drive motors for wire feed and or travel speed
functions.
- The
DMC-500 provides speed and torque regulation using an optical
encoder or phase sampled Back EMF. The embedded controller
provides precise motor braking and anti-plugging features
to extend motor life. Computer Weld Technology's DMC-500
DC Motor Controller can be used as a stand-alone control,
or with the WSC-1000 Thru-Arc System providing motor control
functions for DC motors from 1/10 hp to 1/4 hp.
