## DC Machine: Important Formulas and Electrical Calculations

A **[DC machine](https://forumelectrical.com/dc-machine-core-loss-calculator/)** operates as either a DC generator or a DC motor. Its performance is governed by electromagnetic induction, armature current, generated EMF, back EMF, torque, speed, and power relationships.

The following are the important formulas used in DC machine design, analysis, performance evaluation, and electrical engineering calculations.
