Electric Motor

Possible, but the energy required to drive the motor shaft somehow would be more than the energy generated by the motor generator.

Hi,

Yes you can but you may have to increase the speed some. Note the following web site:

Let use know how the project comes out.

Many DC motor types can work as generators; many AC types can't (unless modified). You might try spinning your motor and checking for output with a voltmeter.

If it works, then experiment further by driving it with a wind or water turbine.

Any motor can be used to generate electric power. The back EMF that limits the current drawn by a DC motor "at free run speed" and that changes the phase angle of the current running through an AC motor is an example of this effect. Some motor designs are easier and more efficient to make well regulated generators of electric power but all will do it.

In the case of your juice mixer motor, you likely have what's known as a synchronous induction motor. As the name implies, these motors synchronize with an external frequency source. When this motor shaft spins at 1500 RPM while connected to a 220VAC 50 Hz source a little bit of real power gets consumed from the 220VAC source to move the cooling air (windage) and to fight the variety mechanical frictions of bearings. If the motor shaft is spun faster than 1500 RPM then real power from the mechanical source puts power into the 220VAC source.

It's more likely to produce electricity by supplying it with juice. S.M.
