|These industrial grade IronHorse
DC gearmotors are manufactured in the U.S.A. by a leading motor
supplier with over 65 years of experience delivering high-quality
motors and gearmotors to the demanding U.S. market. Our supplier
does 100% dynamic testing of the gearmotors before shipment.
IronHorse DC gearmotors are designed for use on unfiltered SCR (Thyristor) type rectified AC input. They may also be used with PWM (pulse width modulated) type DC adjustable speed drives, and in across-the-line applications. The IronHorse line of DC gearmotors features:
IronHorse DC Gearmotors - Parallel and Right-Angle Shaft
IronHorse DC Gearmotor Lineup:
Permanent Magnet DC Gearmotors
The voltage used to power a permanent magnet (PM) DC motor is not pure DC. It is derived by rectifying a supplied AC voltage. The resulting DC voltage has a ripple that is related to the frequency of the AC input.
Form factor is the ratio of Irms to Idc and indicates how close the driving voltage is to pure DC. The form factor for a DC battery is 1.0. The higher the form factor is above 1.0, the more it deviates from pure DC.
Form factor should not exceed 1.35 for continuous operation. Half wave rectification is not recommended as it drastically increases form factor.
Operating IronHorse PMDC motors with DC voltages with form factors higher than 1.35 can result in premature brush failure and excessive motor heating.
