|IronHorse small frame permanent
magnet DC (PMDC) motors are manufactured by a leading motor
supplier with over 45 years of experience delivering high-quality
motors to the demanding U.S. market. Our motors are tested during
production and after final assembly. This is how we can stand
behind our IronHorse motors with full a one-year warranty.
IronHorse DC motors are designed for use on unfiltered SCR
(Thyristor) type and PWM (pulse width modulated) type DC adjustable
speed drives, and on across-the-line DC controls. The IronHorse
line of small DC motors features:
IronHorse Small Frame PMDC Motors
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.
