## What factors do you think will affect the speed of the electric motor?

Factors Affecting Motor PerformanceVoltage of Power Supply.Type of Power Supply.Winding Specifications.Environmental Temperature.Type of Magnet.Flux Yoke.Phase.

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

There is a direct conversion between horsepower and watts: 745.7 watts is 1 horsepower. 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.

## How do you find the speed of a motor?

To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM.

## How do car motors work?

The engine consists of a fixed cylinder and a moving piston. … After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke. In a diesel engine, only air is inducted into the engine and then compressed.

## Which motor is used in lathe machine?

DC shunt motorDC shunt motor is used for driving constant speed line shafts, lathes, vacuum cleaners, wood-working machines, laundry washing machines, elevators, conveyors, grinders and small printing presses etc.

## Can electric motors get weak?

Yes, electric motors can get weaker over time. Bearings wear out and electric insulation breaks down and can start developing shorts in the winding’s.

## How much torque does a 1 hp motor have?

The 3600 RPM, 1HP motor produces 1.5 ft. lbs. of torque at 3600 RPM. So if your 1HP pump was operating at 1800 RPM, the 1800 RPM motor would be producing 3 ft.

## How do I know what size motor I need for my project?

Divide the motor speed by the required speed and round down to get a starting gear ratio. Then divide the required torque by the gear ratio to find the newly required torque. This will help you narrow the choices down to a few select motors.

## What is the most powerful electric motor for go karts?

Mophorn 1800 W Electric MotorThe Mophorn 1800 W Electric Motor is the best electric motor for go-karts in our list, due to its power, superb build quality and it’s high performance-to-cost ratio. As the name already gives away, this electric motor has a power output of 1,800 watts, which is powerful enough for any type of go-kart.

## What is the strongest electric motor?

high temperature superconductorA high temperature superconductor (HTS) developed by Northrop Grumman Corporation and tested by the U.S. Navy holds this title. It is the world’s first 36.5 megawatt (49,000 horsepower) HTS ship propulsion motor.

## How do you determine the horsepower of an engine?

The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower(hp)= Voltage x Amperage x % EFF x power factor x 1.73/746.

## How do you select a motor overload relay?

3. Thermal Overload RelayMin. Thermal Overload Relay setting = 70%x Full Load Current(Phase)Min. Thermal Overload Relay setting = 70%x4 = 3 Amp.Max. Thermal Overload Relay setting = 120%x Full Load Current(Phase)Max. Thermal Overload Relay setting = 120%x4 = 4 Amp.Sep 11, 2013

## How do you make a motor faster?

One easy way to make the motor run faster is to add another magnet. Hold a magnet over the top of the motor while it is running. As you move the magnet closer to the spinning coil, one of two things will happen. Either the motor will stop, or it will run faster.

## How do you specify a motor?

The first key thing you should know is power, measured in either horsepower for NEMA standardized machines, or kilowatts typically for IEC standardized machines. Horsepower (HP) measures the amount of power a motor can give defined by torque multiplied by speed divided by 5250 feet pounds.

## How do I know what engine to use?

Consider an application’s purpose and which current it uses to select the appropriate type of motor. An application’s specifications such as voltage, current, torque, and velocity will determine which motor is most appropriate so be sure to pay attention to its requirements.

## How fast do electric karts go?

50MPHHigh Speed Indoor Electric Karts. Each adult kart has a 20 horsepower electric motor that reaches speeds up to 50MPH, while the junior karts reach speeds up to 25MPH.

## What is a torque in motor?

The torque is the twisting force that makes the motor running and the torque is active from 0% to 100% operating speed. The power produced by the motor depends on the speed of the motor and is. zero at 0% speed, and. normally at it’s top at operating speed.

## 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 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%.
