Question:

If u connect a DC motor to AC will it run or burn up?

I have 2 dc motors running off a 12 volt battery charger. It works but the motors run very slow. What can I do to make them run faster. Can I use a power inverter to convert 110v, ac into 24v, dc?

Answer:

Most converters won't handle the load of a motor. Find the load in amp.s, (It will be on the motor). Multiply the amps. x 12V. This will give you the running Watt.s. Multiply the Watt.s x 2 to get the minimum transformer size. (Motors need the extra capacity to start up). Buy a 120/12V. transformer of at least that capacity, and a 12V. rectifier bridge with minmum twice the motor running amp.s capacity. Buy a single pole light switch. Wire your 120V. power to the switch, and then to the line side of the transformer (According to Code please). The wire the transformer to the bridge. Wire the switch and thence to bridge to the motor. Given up the idea yet? Do be sure that there's a manual latch to get you out of your Secret Room in case your amateur lash-up fails.
first check is the current supply on by touching the main wire
if they run slow on 12v then may i suggest you read the plate on the motor to see what they require as far as voltage and the current they need to operate as designed. if there is no plate search for a part number.and yes once you figure that out then it is just a matter of getting the right step down transformer with the neccessary voltage and amperage
