Can a circular saw motor be used as a wind turbine motor?
and why not
Answer by soobie_cooli would think so if you took off the gard and atached a tubine
What do you think? Answer below!
depends on the type of motor, and what speed it’s driven at. (I assume there’s a gearbox to increase shaft speed)
If it’s got permanent magnets there’s should be no problem what so ever with getting power from it. The output would probably need some processing though to make it “clean”.
The case of an induction motor came up just the other day in a forum, I’m involved in ( I think it was yahoo groups “Home brew power”) If an induction motor has (some?) of it’s windings connected to the grid, and is driven faster than it’s rated speed (up to about 110%), it’s able to put electricity back on the grid, and the phase of that power will be EXACTLY in phase with the grid. (of course this still needs a grid…)

please go to Youtube and see if somebody has done that.
No, probably not.
They are actually DC motors, with the commutator and brushes arranged to reverse the fields of the rotor as the rotor spin. This allows the motor to use AC of any frequency (including the limiting case, DC), which is why they are called universal motors.
They are high speed motors with poor speed control, and no magnets. As a result, they don’t initially generate electricity when spun because there is no magnetic field. There’s no magnetic field until the current starts to flow. Also, the trick of using power from the grid then overdriving the motor doesn’t work, because the motor will just speed up and commutate the rotor field faster. The high speed means that you need a gearbox. The one on the circular saw will not be efficient when driven in reverse.
Try some other type of motor, most can be used as generators.
If you insist on trying the universal motor, I would add some magnets to give some current as the rotor spins. This could be enough to start and maintain the generator function.
