# Question: How To Build An Electric Scooter Using An Alternator As A Bldc Motor And Home Made Speed Controler?

## Can you run an alternator with an electric motor?

You can use a DC motor to drive an alternator in order to invert a DC energy supply into AC. But you would be setting up a system with needless mechanical complexity. It would not be economical to needlessly drive an alternator by an electric motor. Magnetic force in an alternator causes a mechanical resistance.

## How powerful is an alternator motor?

There are many 120+ amp alternators on trucks/SUVs, but that’s at approx 14 volts=approx 1700 watts. Any alternator can generate 120 volts if you spin it in its upper rev range and feed it max field current.

## Which motor is used in electric scooter?

Electric scooters have brushless direct current (BLDC) electric motors that are built into the hub of wheels. All electric kick scooters have at least one motor while more powerful ones will have two.

## Can you use an alternator to generate electricity?

Yes, alternators generate electricity most efficiently when driven by an internal combustion engine. Their application in a motor vehicle is common. Also as a stationary power source to charge batteries for off the grid power. But you may be considering a wind driven alternator for off the grid power.

## How do you make an electric motor more powerful?

We can increase the turning force (or torque) that the motor can create in three ways: either we can have a more powerful permanent magnet, or we can increase the electric current flowing through the wire, or we can make the coil so it has many “turns” (loops) of very thin wire instead of one “turn” of thick wire.

## What is the minimum RPM of a 12v car alternator?

As was stated before, most alternators prefer a minimum speed of 2,400 rpm.

## How much horsepower is required to turn an alternator?

How much power does it take to run an alternator? An alternator typically takes about 1 HP ( horse power ) for every 25 amps of power generated. So, a 100 amp alternator will require about 4 HP at full output. Most alternators do not operate at full output for very long.

## Does it matter which direction an alternator spins?

Alternators are directional (technically). Having said that, it doesn’t matter what direction you turn them to the mechanicals of the alternator except for the cooling fan. Common automotive alternators produce synchronized (120 Degree intervals) 3 Phase AC Current.

## What happens if you spin an alternator backwards?

It will probably burn out unless you change the pulley and fan. Those fan blades are angled to draw as much airflow through the alternator as possible. Turning backwards they will be fighting against the normal flow.

## How much power does a alternator motor produce?

Most alternators put out between 60 to 200 amps. So be careful as It may appear to be a short to your house current. Use a remote switch.

## How much power can a car alternator produce?

But nowadays, a single alternator can produce power up to 2500 Watt, depending on the power demand. The power that can be produced by an alternator is determined by the alternator rating. The output of the alternator ranges from 40 Amp up to 120 Amp. For high-amp alternator, it can generate up to 300 Amp.

## Does Tesla use AC or DC motors?

Tesla, for example, uses alternating current ( AC ) induction motors in the Model S but uses permanent-magnet direct current ( DC ) motors in its Model 3. There are upsides to both types of motor, but generally, induction motors are somewhat less efficient than permanent-magnet motors at full load.

## How can I make my electric scooter faster?

How to Make an Electric Scooter Go Faster

1. Remove the Speed Limiter. Every scooter is built with a speed limiter since this is the component that helps to make sure the motor doesn’t overpower the battery.
2. Improve the Battery Power.
3. Add a Battery.
4. Upgrade the Motor.
5. Increase Aerodynamics.
6. Find Better Terrain.

## Which type of motor is used in electric vehicles?

The Brushless DC Motor (BLDC Motor ) in Electric Vehicles Today’s automakers use three different types of electric motors in green cars: the BLDC motor, brushed DC motor, and AC induction motor. The BLDC motor has a permanent-magnet rotor surrounded by a wound stator.
