What are three things needed in an electric motor?
Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually as long as it receives a steady flow of electric current.
What should I look for when buying an electric motor?
To determine the technical specifications, it will be necessary to determine the power, torque and speed of the motor. In order to determine the size, you must know how much space the motor will take up and how it is mounted (i.e.how it will be fixed in the system).

What are the principles of electric motor?
The electric motor works on the principle of magnetic effects of current. Its principle is when a rectangular coil is placed in a magnetic field and current is passed through it, the coil rotates as a result of the forces acting on the coil.
What size electric motor do I need?
General rule of thumb: you need at least 2 lbs. of thrust for every 100 lbs. of fully-loaded boat weight (people and gear included). If things like wind or current are major factors where you fish, you’ll want a little extra thrust.
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. 1.
How do I know what size electric motor I need?
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.
How do you make an electric motor spin faster?
The speed of rotation of the coil can be increased by:
- increasing the size of the current;
- using a stronger magnet;
- increasing the number of turns of wire in the coil;
- reducing friction between the coil and the axel it rotates on.
What can I make with a small electric motor?
Small motors can add motion to holiday centerpieces. Turn a small DC motor into a revolving holiday showpiece. Low-RPM hobby motors are great for making holiday mobiles and centerpiece displays, and small battery-powered turntables are ideal for creating attractive revolving holiday centerpieces.
