Re: CIM motor + Electrical outlet = ?

I'm planning to invest in some CIMs for a home made project.
A CIM motor is rated for 12V DC (direct current). Electrical mains voltage is 60Hz 120V AC (alternating current).

To run a 12V DC motor off of 120V AC mains, you'd need an electrical transformer/power supply to both convert alternating current to direct current and to step down the voltage from 120V to 12V.

The stall current of a single CIM motor is 133 amps at 12v, which means it's using 1596 Watts of electrical power (but at this point is outputting zero watts of useful mechanical power, at the expense of becoming an excellent space heater). This means the power supply you choose to run the CIM motor must be capable of sinking at least 1596 Watts of output power. Buying a 120VAC->12VDC power supply capable of outputting at least 1596W will put a several hundred dollar dent into your wallet.
