In this case, the torque of the DC motor can be adjusted by controlling the armature supply. The value of φ is constant because permanent magnets of the required flux density are selected at the time of manufacture and cannot be changed thereafter. It provides support to the armature, windings, and commutator.Ĭheckout this article: What Are The Fundamental Parts of Transformer? Types of DC Motorsįollowing are the three main types of DC motors:īy applying the torque equation of the DC motor,.from brushes, converts it into A.C., and supplies it to the armature windings. This flux reacts with the main field flux and produces rotation or torque.Ĩ) Commutator: It collects D.C. It covers the armature and protects it.Ħ) Armature Core: It houses the windings in the slot and provides a low reactance path to the main field flux and the armature flux.ħ) Armature Windings: It produces armature flux when current is passed through them.Supports the bearings in which the armature rotates.from the main and supply it to the armature winding through a commutator. is passed through them.Ĥ) Brushes: They receive D.C. Distributes the main field flux uniformly all around the periphery of the armature.ģ) Field Windings: They produce a magnetic field when D.C.
