AN INVESTIGATION INTO THE EFFICIENCY OF A D. ... MOTOR
{PLANNING
P2a – P8b
Aim: The aim of this experiment is to investigate the relationship between the input and output power of an electric Direct Current (D. ... ) motor. ... Several factors, such as efficiency, are important. The efficiency of the motor can be measured using the following formula:
Efficiency (%) = (Output Power / Input Power) X 100
Before carrying out an investigation such as this, it is extremely important to understand how an electric motor works. The basic science concepts that explain the motion of an electric motor are:
(1) Like poles of a magnet repel and unlike poles of a magnet attract
(2) Electric current flowing through a conductor produces a magnetic field that has both a North and a South Pole.
An electric motor is, in essence, a spinning electromagnet. ... Motor like the one that is being used for this investigation. ...
To investigate the efficiency of a motor, the power input and the power output are the variables which must be investigated.
