Dc Motor Making Science Fair Project
How it works on connecting the battery in the battery socket you will observe that the armature connected between the two semicircular bracket starts spinning With very high speed. Why: an electric motor is a machine for converting electric energy into mechanical energy. It is based on the fact that a current carrying coil in a magnetic field experiences induced force and its direction can be given by fleming’s left hand rule. The coil is in horizontal direction in the beginning. Current from the battery flows through the conducting wire and through the coil. This produces the induced some funm.F. With this an upward force acts on half of the part of armature and other and downward force on rest of the half part. This forces form a couple and the coil rotates in clockwise direction. As a result a coil becomes vertical and the copper brushes change their position of contact. This results into direction of couple same and the coil gets momentum in the same direction, consequently the coil rotates continuously. The speed of rotation depends on the number of turns in the coil, strength of magnetic field and current flowing in the coil.
