# Question: What is the most powerful electric motor for a car?

Contents

## How big of an electric motor is needed to power a car?

Car motors for modern vehicles range from about 50 horsepower to 500 horsepower or more. An average medium size family car might have a 150 HP motor. To duplicate that with an electric motor you would need 111,855 watts of power.

## Which motor is most powerful?

Which Motor Is More Powerful: AC or DC? 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.

## How much horsepower can an electric engine produce?

Electric Motors

An electric motor’s output is measured in kilowatts. Companies that build electric cars continue to talk about horsepower because consumers are still more familiar with that type of unit. The equation is as simple as hp = kW x 1.369, so a 100-kW motor produces 136 horsepower.

## How high can an electric motor rev?

A typical electric motor can rev at up to 20,000rpm, far higher than the usual 4,000-6,000rpm limit for a normal road car. Also, electric motors are power-efficient throughout that rev range. This means they don’t only deliver their optimum performance within a small, narrow rev band.

## What is the easiest car to convert to electric?

The easiest cars to convert to electric would be VW and Porsche air cooled vehicles such as Beetles, Karman Ghia, Bus, Squareback, Fastback, Porsche 912, 911 etc from 1950s to 1975+.

## How much does it cost to convert a vehicle to electric?

A typical conversion, if it is using all new parts, costs between \$5,000 and \$10,000 (not counting the cost of the donor vehicle or labor). The costs break down like this: Batteries – \$1,000 to \$2,000. Motor – \$1,000 to \$2,000.

## How powerful can a motor be?

It is the world’s first 36.5 megawatt (49,000 horsepower) HTS ship propulsion motor. … Its capacity surpassed the Navy’s previous test record, doubling the rating. The HTS motor performs at 120 rpm and produces 2.9 million Newton-meters of torque.

## What is the fastest electric motor?

The British appliance manufacturer Dyson claims to have developed the world’s fastest, most efficient motor for domestic appliances. The Dyson Digital Motor (DDM) v2 is a single-phase brushless DC motor, which operates at speeds up to 104,000 rpm with a claimed efficiency of 84%.

## What is the toughest part of an electric car?

“Everyone recognizes the battery is the most important and challenging component of an EV because it determines the crucial factors such as the range, how much the vehicle is going to cost, safety, convenience of recharging the vehicle,” said to Bryan Kelly, an R&D engineer at Synopsys.

## How fast can an electric motor go?

Two pole AC motors operating at 60 Hz will always run at approximately 3600 rpm, and four pole AC motors will have speeds around 1800 rpm. Example 120 x 60 hertz / 4 poles = 1,800 rpm.

## Do electric cars need oil?

An electric car doesn’t require motor oil, as it uses an electric motor instead of an internal combustion engine. Traditional gas vehicles need oil to lubricate several moving pieces in their combustion engines. … Thus, regular oil changes aren’t necessary for electric vehicles.

## What determines the strength of an electric motor?

Strength of a motor:

The strength of the motor (torque) is determined by voltage and the length of the wire in an electromagnet in the stator, the longer the wire (which means more coils in the stator) the stronger the magnetic field. This means more power to turn the rotor.
