# Question: How Do I Know What Size Motor I Need For My Project?

## What is the fastest electric go kart?

Daymak C5 BlastThe world’s fastest go-kart is the all-electric Daymak C5 Blast and it can zoom from 0 to 60 mph in just 1.5 seconds..

## 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 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 is motor rating calculated?

Multiply the motor voltage by the full-load current. The result is in watts. Divide watts by 1,000 to give kilowatts. For example, 230 volts x 20 amps = 4,600 watts; 4,600 watts divided by 1000 = 4.6 kilowatts.

## How do you calculate motor load capacity?

It is combination from Amperage and Voltage value. Basic formula for Power is P (watt) =I(ampere) x V (volt). Power also measured in Horsepower (hp) unit. For common conversion from electrical Horsepower to Watt is 1hp = 746 watt.

## How do you determine how much torque you need?

The required torque is calculated by multiplying the sum of load torque and acceleration torque by the safety factor. When the required torque for the motor varies over time, determine if the motor can be used by calculating the effective load torque.

## How do you calculate kV torque?

Therefore, the torque a motor produces is τ=KtI. The SI unit of Kt is the weber. So a lower Kv implies a higher Kt; a higher Kt means the motor will produce more torque from a given amount of current.

## How is horsepower calculated?

Power = (Force x Distance) / Time For electric motors, power or horsepower can be calculated from the torque and speed. For example, if you have a motor rated for 3,000 RPM and 6 in-lbf then the horsepower is calculated below.

## How much weight can a 1 hp motor lift?

about 550 lbsThis means with 1 hp, you can lift about 550 lbs (250 kg) at a rate of 1 ft/sec, 1100 lbs at a rate of 0.5 ft/sec, 225 lb at a rate of 2 ft/sec, 1 lb at a rate of 550 ft/sec, and so on.

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

The key indicator for determining fan motor size is fan brake horsepower (BHP), which represents the force needed to brake, or stop, the motor. This is the minimum amount of power needed to operate the fan. Your fan manufacturer will always specify brake horsepower.

## Does lower KV mean more torque?

Torque is determined by the number of winds on the armature and the strength of the magnets. A low Kv motor has more winds of thinner wire—it will carry more volts at fewer amps, produce higher torque, and swing a bigger prop.

## Is a higher kV motor better?

Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor would be faster than a 2200Kv motor. … A higher turn number means more wire and thus more resistance, resulting in a slower motor. So turns with a lower number means a faster motor.

## How is kV brushless motor calculated?

The formula to calculate Kv for a brushed DC motor is to just divide the speed by the generated DC voltage that you measure using your multimeter. Another option for brushless motors is to buy a BL motor tester that will calculate Kv for you. One example of this tester is here, but there are other available out there.

## 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 torque measured in?

Newton metresTorque is usually measured in Newton metres (Nm), or pound feet (lb-ft) – the latter not to be confused with foot pounds (ft-lb), as one ft-lb refers not to a twisting force, but to the amount of energy required to raise a 1lb weight by a distance of 1ft.

## How do I choose engine size?

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.

## How is fan BHP calculated?

BHP = Q x SP / (6356 x Fan Ef f.)

## How do you select a conveyor motor?
