# What is the input and output of an electric motor?

Contents

For an electrically driven motor, the output power is mechanical while the input power is electrical, so the efficiency equation becomes efficiency = mechanical power/electrical input power.

## Is a motor an input or output?

These components are split into the three categories: processes.

Output.

Output device Function Use
Motor Converts power into rotary motion that can turn a spindle linked to gears or wheels to make them move Cars and trains

## What is electrical input and output?

Input​ refers to the amount of energy put into a device, and ​ output​ refers to the amount of energy that comes out. … For example, a light bulb’s input energy is the form of electrical energy, and its output energy is in the form of light and heat.

## What is the power output of an electric motor?

Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor’s efficiency tends to decrease dramatically below about 50% load.

## What is an input energy of a DC motor?

THE DC MOTOR’S INPUT IS ELECTRICAL ENERGY. OUTPUT IS MECHANICAL ENERGY.

## What is the output of a motor?

In an electric motor, the mechanical power is defined as the speed times the torque. Mechanical power is typically defined as kilowatts (kW) or horsepower (hp) with one watt equaling one joule per second or one Newton-Meter per second. Horsepower is the work done per unit of time.

## What is input power of motor?

For an electrically driven motor, the output power is mechanical while the input power is electrical, so the efficiency equation becomes efficiency = mechanical power/electrical input power.

## What is output power input?

Input power is the power consumed by a device. Output power is the power supplied by the device.

## Is a scanner input or output?

Scanner is an input device used for direct data entry from the source document into the computer system. It converts the document image into digital form so that it can be fed into the computer.

## Do electric motors have horsepower?

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.
