Induction motor generator some q's

[wantfreeenergy]

I've got my geet engine and I also have been given a 3-phase 15hp induction motor. It can be wired for 203-230/480 voltage power. But I don't know how to check the motor to see if it works first of all. "ie. where do I put the ohm meter." I'll try to get a picture asap of the diagram on the motor.

In the mean time does anyone have a link or some answers that will answer my q's. I wanna make sure the thing works and if it does I want to produce 240 power and hook it into my dryer outlet.

There's 9 wires. I need to get a pic it'll help.

thanks in the meantime

Right now it's hooked up as the second image img 16. The one where the wires #1 #2 #3 are by themselves. The high voltage diagram.

Now from here how do I check the coils with my ohm meter to make sure the motor works.

And also I want to use 230 voltage so i think I need to wire it up like the first image. Low Voltage. But once it's wired up like so how do I hook it up to a 240 plug. I need more info before I fully understand how it works.

Thanks

Hi Wantfreeenergy,

using an induction motor as a generator can be tricky to get it working. It is a quite complex task.

Maybe you want to understand the principles with a single phase version first.

See: Induction Generator

To use an ordinary induction motor as a generator you need to:

- drive the generator faster than the rated speed of the motor
- connect the right capacitors to create reactive power for the necessary magnetic fields
- take the kind of load into account. Ohmic loads are fine, heavy reactive loads can extinguish or weaken the field generating currents which alters the voltage generated.
- start and stop the generator without an electrical load connected to maintain some magnetism inside the machine for the next startup.

I do not have own experiences with that, so I can give no further advice.

Wantfreeenergy,

Howie is correct
You can approach the problem as if it was 3 generators in one! OR

Combining the phases into house ac, is not easy without a DC stage and an inverter.
If you want to do that inverter method, your motor is like the alternator on your auto.
The circuit for an automotive alternator - battery charger, is what you want to study
for 3 phase conversion to DC.
Its; The caps Howie wrote about, 9 diodes a regulator (your engines governor?) and
a battery(s) or bank of super caps (or both ) connected to your inverter...
Since the voltage is already high, your inverter is a push pull oscillator connected to
a 1:1 isolation transformer.
