The IronHorse permanent magnet DC 56C-frame motor line features totally enclosed non-vented (TENV) and totally enclosed fan-cooled (TEFC) models. The motors are constructed of a rolled steel frame with cast aluminum end bell and are available in sizes ranging from .33 HP to 2 HP. IronHorse DC motors are ideal for applications such as conveyors, turntables, and whenever adjustable speed, constant torque, dynamic braking and reversing capabilities are needed. IronHorse DC motors, with a base 1800 RPM, are designed for use on unfiltered SCR (Thyristor) type 115 or 230V rectified AC inputs, when used with an appropriate SCR drive. They may also be used with PWM (pulse width modulated) type DC adjustable-speed drives.
