* Form Factor
The voltage used to power a permanent magnet (PM) DC motor is not always pure DC. It is often 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. The Form Factor Table shows examples of commonly used voltages. 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.
