|IronHorse electric motors are
manufactured by a leading motor supplier with over 20 years
experience delivering high-quality motors to the demanding U.S.
market. Our supplier produces these permanent magnet DC motors in
an ISO9001 facility which tests the electric motors during
production and after final assembly. This is how we can stand
behind our IronHorse 56C permanent magnet reversible DC motors with
a two-year warranty.

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.
