Permanent magnet dc motors
The IronHorse permanent magnet dc 56C-frame motor linefeatures totally enclosed non-vented (TENV) and totally enclosed fan-cooled(TEFC) models. The motors are constructed of a rolled steel frame with castaluminum end bell, and are available in sizes ranging from 0.33 to 2 hp. Themotors are suitable for conveyors, turntables and other applications whereadjustable speed, constant torque, dynamic braking and reversing capabilitiesare needed.
With a base speed of 1,800 RPM, the dc motors are designedfor use on unfiltered SCR (Thyristor) type 115 or 230 V rectified ac inputswhen used with an appropriate SCR drive. They may also be used with pulse widthmodulated (PWM)-type dc adjustable speed drives.
Other features include linear speed/torque characteristicsover the entire speed range, high starting torques for heavy load applications,reversible rotation and dynamic braking capability for faster stops. Largebrushes provide for longer brush life. Motors are shipped with a set of brushesin the motor, with an extra set of brushes included in the box.
