I have a blower fan that pulls 12V DC and 2.6-3 amps, I'm

I have a blower fan that pulls 12V DC and 2.6-3 amps, I'm trying to make a workaround so I can plug it into an AC power outlet. So, I got a transformer like you would find on a laptop that converts standard AC to 12V 3 Amp DC. When I connected the wires though, the fan only puts out a weak pulse. I read somewhere that when translating AC to DC you're effectively cutting out half of the wave sign and therefore will only get the arcs from the positive half, which would naturally be intermittent or "pulsing." But it's also my understanding that transformers are supposed to "rectify" that, and I've tried this with two transformers now and they both cause the fan to pulse. Is there another component I need to pass the current through to make the fan have a continuous current? If it's any help, this is a diagnostic of the fan that I'm using, it's the Turbo 3000.Thanks!-forrest

I want to hook up an air compressor, 3-phase 220 volts. However, our electrical output, as measured, is about 208 volts. Is there a way to step up the voltage? Will using 208 volts ruin the motor?

Hello. A fellow working for me disconnected the key controller to my older Dayton two direction 120VAC swimming pool cover motor, and did not make a correct notation of the connections to the motor. I have a wiring schematic from the controller manufacturer, and some information from Dayton (Grainger) but have been unable to correctly connect the motor. I need plain language instruction on where to place each motor wire on the controller.
