DC Motor

A motor that runs on direct current electricity, converting electrical energy into mechanical rotation with variations like brushless or brushed types.

Load Torque

The torque required by a load, the resistance against which a motor or engine works to cause rotational movement.

Armature Resistance

Resistance within the armature of an electric machine, such as a motor or generator, which can affect efficiency and performance by opposing current flow.

Mechanical Rectifier

A device that converts alternating current (AC) into direct current (DC) through mechanical means, historically used before electronic rectifiers became common.
