If i hook up a Vacum motor to a car battery will it rum or blow out?
Dud and Moose are right on. Universal AC Motors: Universal ac motors operate with nearly equivalent performance on direct current or alternating current up to 60 Hz. AC motors differ from a dc motors due to the winding ratios and thinner iron laminations. DC motors runs on ac, but with poor efficiency. Universal ac motors can operate on dc with essentially equivalent ac motor performance, but with poorer commutation and brush life than for an equivalent dc motor.
uncle dud is a DUD at electronics!! DC 'can not' run an AC motor!! DC stands for direct current,, it is a straight continuous voltage,, AC is alternating current,, a motor using AC needs the up and down cycles of the AC to run,,, DC will just put a straight current into the motor, heat things up to melting!!!! and the battery will probably explode...and no,, there is no such thing as a universal vaccum cleaner motor!! if you have a small hand vac that uses both then the motor is only a DC motor,, it comes with a transformer that changes the AC to DC to use with house voltage!!!!!!!!!!!
Most vacuums use motors made by Amtec-Lamb. They are brush type motors and will run on AC or DC. (the only motors that require AC only are capacitor or induction start types. And not used in vacuums). The motor you have will probably run very slow and not create any vacuum.
I assume a vacuum motor out of house vacuum that normally runs on 120 Volts. The answer is will most likely run slowly. Most vacuum motors are something called universal motors which run on AC or DC. There speed is proportional to the voltage and load applied. Since your voltage is about 10% of rated it will run very slowly if it will overcome friction.
A normal vacuum cleaner motor is 110VAC and a car battery is 12VDC. No, the DC power source will not start an AC motor. If you have one of those rechargeable vacuums like a Dustbuster or swiffer, they do have DC motors and a car battery will get the motor running. Look at the voltage requirements for the motor, usually on a sticker on the appliance or on the charging transformer. If it is at or near 12VDC, the motor should run just fine. If the motor voltage is considerably less than 12VDC, the battery will make the motor overspeed and possibly burn out the windings. If it is more than 12VDC, the motor will not come up to speed and possibly overheat due to lack of circulation of cooling air and burn out the windings.
