Two methods, one uses a dial that is held in the center of the revolving shaft and is directly read off of the dial face. The second method uses a strobe light. The light is focused on the shaft and the dial on the strobe is turned until it looks like the shaft has come to a stand still. The RPM is read off of the meter face of the strobe light.

Do you measure amps on 220 volt electric motor by measuring one line or both and combining total of the two?
In a single phase 220 volt electric motor just measure one line. That already represents your line current. That line current is equal to your total current circulating in your motor.
What is a machine that turns mechanical energy into electrical energy?
Electric motor.
What is output of an electric motor?
An electric motor converts electrical energy to kinetic energy.
What has to occur for an electric motor to spin freely?
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.
Electric motor parts?
Electric motor parts are pieces of electric motors. Some examples of electric motor parts are: bearings, carbon brushes, gasket materials, pumps, soft starters, and terminal boxes.
How do you measure RPMs on an electric motor?
There is an instrument that used a strobe light to check shaft rotation on a motor. It is somewhat like the timing light that is used on vehicle engines to check their timing. There is also a mechanical dial device that is physically touched to the pully or gear end and center of the turning rotor shaft and the RPM is read right off of the dial face.
Can an electric motor work without a magnet?
Most electric motors require magnet to operate on the principal of attraction. A motor can operate without any permanents magnets by replacing the with another coil of wire.

What is the point of having an electric motor?
It makes work easier than doing everything by hand without the motor.
What is the function of an electric motor in terms of electric power and motor?
The electric motor changes electric energy into mechanical energy.
What changes electric energy into motion?
An electric motor
How can you stop an electric motor without getting close to it?
Easy, you just switch it off!
Without the engine a car can't run right?
Unless it is all electric - then it has a motor.
When do we use the electric motor?
An electric motor is used when an internal combustion engine is not practical. They are capable of being used in very tiny or large applications without producing any emissions.
What is the importance of the electric motor?
The importance of the electric motors is that it provides a motor which can be operated without volatile fuels or harmful exhaust. It provides consistent power which can be operated in nearly any environment.
How do you test an electric motor without a meter?
Turn it on... Does it work ? Yes - job done No - Bummer!
Which conversion does an electric motor make?
electric energy to mechanical energy
