Description

This lecture explores the operation of a direct current motor as a generator, focusing on the role of the commutator. The induced voltage equation is derived for a simplified motor with a single coil. The stator creates the excitation flux, either through coils or magnets, affecting the ability to vary the flux density. The induced voltage in the rotor coil is proportional to the rotor's angular velocity. The lecture also covers the use of a commutator to rectify the induced voltage, creating an alternating voltage proportional to the rotor's speed.
