Your question: Can I use an AC motor for a wind turbine

Simply take any old AC motor, add magnets to the rotor, put it in the wind and you have power. A fan motor, no matter if its a box fan, table fan or a huge gigantic barn fan, will work perfectly well for this. Take any AC motor with fan blades on it.

What kind of motor do I need for a wind turbine?

You should be looking for a motor with a minimum amperage rating of at least 5 Amps. Anything above 5 Amps and you are good to go. Remember, the more amps and volts the wind generator creates the more power it is producing!

Can you use an AC motor as a generator?

Induction generators operate by mechanically turning their rotors faster than synchronous speed. A regular AC induction motor usually can be used as a generator, without any internal modifications. … An induction generator usually draws its excitation power from an electrical grid.

Do wind turbines use AC or DC?

The generator in a wind turbine produces alternating current (AC) electricity. Some turbines drive an AC/AC converter—which converts the AC to direct current (DC) with a rectifier and then back to AC with an inverter—in order to match the frequency and phase of the grid.

Can you run AC motor on DC?

An AC motor cannot run on an DC SUPPLY.. … When an AC supply is given to An DC motor ,the direction of current changes for every half cycle ,since in practical motors we use field winding instead of an permanent magnet,so the direction of current in field winding also changed resulting in reversal of direction of flux ..

Which motor is best for generate electricity?

Rule #1: For generation of DC voltage select a brushed DC motor or use a brushless EC (BLDC) motor with voltage rectifier. For the generation of AC voltage, select a brushless EC motor and connect 2 phases only. Hall sensors are not needed on brushless motors.

What is the rpm required to generate electricity?

1,000-1,800 rpm is the rotational speed required by most generators to produce electricity. The high-speed shaft drives the generator which produces AC electrical current.

Can you turn a 3 phase motor into a generator?

Yes, a three phase motor CAN be spun to operate as a generator, however, an induction motor used as such will still require a supply voltage, will Have to be spun faster than its normal operating speed and cannot provide reactive power, so would need a capacitor [bank].

Can a single phase motor be used as a generator?

The purpose of the paper is the investigation of possibility of utilization of a single-phase induction machine, designed and normally operating as a single-phase capacitor induction motor, as a self-excited single-phase induction generator, which can be used to generate electrical energy from non-conventional energy …

What is the difference between an electric motor and a generator?

Converting energy from one form to another is the key to understanding the differences between electric motors and generators. An electric motor converts electricity into mechanical energy, providing a power source for machinery. A generator does the opposite of this, converting mechanical energy into electricity.

How many volts does a wind turbine produce?

On large wind turbines (above 100-150 kW) the voltage (tension) generated by the turbine is usually 690 V three-phase alternating current (AC).

Why does wind turbines have 3 blades?

Having fewer blades reduces drag. But two-bladed turbines will wobble when they turn to face the wind. … With three blades, the angular momentum stays constant because when one blade is up, the other two are pointing at an angle. So the turbine can rotate into the wind smoothly.

What voltage do wind turbines generate?

A modern wind turbine is often equipped with a transformer stepping up the generator terminal voltage, usually a voltage below 1 kV (E.g. 575 or 690 V), to a medium voltage around 20-30 kV, for the local electrical connection within a wind farm (distribution level).

Is a DC motor better than an AC motor?

AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.

What will happen if we give DC supply to AC motor?

(2) The other effect of the DC supply on the AC motor is that if we give DC supply on the AC motor then the windings of the AC motor may be burn because when the one reason is AC windings always have less resistance than DC windings and the other reason is when we give DC supply on the AC motor there are no Self- …

How can you tell if a motor is AC or DC?

Look for the commutator & brushes and salient field system to confirm. (iii) has 5 terminals, then it is a AC synchronous motor (3 for stator and 2 for field). Look for 2 slip rings for rotor dc supply. (iii) has 4 terminals, then it may be a DC motor, in which case look for the commutator & brushes to confirm.
