# Electric Motor Power: 180 HP & Car Fitment

• QAT
In summary, the Tesla Roadster electric car has a 3-Phase Alternating Current Induction Motor that weighs 115 pounds and can deliver 288 peak horsepower and 295 lbs-ft of torque. To achieve 180 horsepower, a 135 kW output electric motor is needed, and to power it, 375 volts and 900 amps of current are required.
QAT
The first question, is their any electric motor (ac/dc) that has 180 horsepower and can fit comfortabley in a car. Second question, (if no for the first question disregard this one) how much power would be needed to power it, amps and voltage.

The Tesla electric car comes to mind:

The Roadster is powered by a 3-Phase Alternating Current Induction Motor. Small, but strong, the motor weighs just over 115 pounds. 375 volts push up to 900 Amps of current into the motor to create magnetic fields. It delivers 288 peak horsepower and 295 lbs-ft of torque at the driver's command. At top speed, the motor is spinning at 14,000 revolutions per minute.

Note that one horsepower = 745.699872 Watts (according to Google Calculator, anyway.) This means that if you need 180 HP, you are looking at a 135 kW output electric motor, to give you an idea of what you need :)

The Tesla one would be 288 hp, which is 215 kw. That means you need more power than that to actually spin the motor, if I'm not mistaken. According to 375V, 900A, 3 phase AC, that's... 550kW? That seems high...

## 1. What does "180 HP" mean in terms of electric motor power?

"180 HP" stands for horsepower, which is a unit of power. It indicates the maximum amount of power that the electric motor can produce. In this case, it means that the motor has a power output of 180 horsepower.

## 2. How does the power of an electric motor affect a car's performance?

The power of an electric motor directly impacts a car's acceleration and maximum speed. A higher horsepower motor can provide quicker acceleration and a higher top speed compared to a lower horsepower motor.

## 3. Can an electric motor with 180 HP be used in any type of car?

No, the compatibility of an electric motor with a car depends on various factors such as the size and weight of the car, the type of transmission, and the battery capacity. It is important to ensure that the motor is suitable for the specific make and model of the car.

## 4. Is 180 HP considered a high power output for an electric motor?

It depends on the context. In the world of electric motors, 180 HP is considered a high power output compared to smaller motors used in household appliances. However, in the automotive industry, there are electric motors with much higher power outputs, some reaching up to 1000 HP.

## 5. How does the power of an electric motor compare to a gasoline engine?

In general, electric motors tend to have higher power outputs compared to gasoline engines of the same size. This is because electric motors can deliver their maximum torque instantly, while gasoline engines require time to build up torque. Additionally, electric motors have a wider power band, meaning they can maintain their power output over a larger range of speeds compared to gasoline engines.
