Question:

Powering a dc motor with an ac generator.?

I want to bypass having to get 4 deep cycle batteries for my project. I need to power 2 24v 200w motors. I was considering a 2 cycle 1000w generator. I know I need an AC to DC converter, but what kind would I need in terms of stats. (Watts, volts and amps) would it just be better to go with the deep cycles?

Answer:

MOTORS NEED AT LEAST 16,67A AT 24V GENERATOR REQUIRES ABLE TO PROVIDE BETWEEN 26.67Vac BUT NOT MORE THAN 30Vac ,PROVIDES CURRENT AT LEAST 16.67A OR HIGHER IS BETTER.. A FULL WAVE RECTIFIER RATED ANY BETWEEN 100V TO 400V , ANY CURRENT RATE BETWEEN 35A TO 50A IS GOOD ENOUGH, COST JUST $2 PIECE, MUST MOUNT IT WITH HEAT SINK.
There is no deep cycle generator. You need 24VDC 500W generator. A 1000W 24Vdc, generator would be plenty. 4 cyc/e would be much better because 2 cycle is really noisy. Deep cycle is a Battery specification.
If you used a standard 1000 W generator that put out 120 VAC, you would need two transformers with a primary of 120 VAC and a secondary of 24 VAC 10 amps - one for each of the motors. In addition to the transformers, you would also need two bridge rectifier modules (one for each). Good rating to look for would be 100 PIV 30 amp. The 30 amps is because motors tend to draw high start up currents.
