Topics covered in this video: circuits, current, magnets, electromagnets, armature, commutator, brushes, stator, and rotor. This video only covers DC motors. Maybe I will cover AC motors in a ...

The torque constant and the torque produced by the rotor allow us to calculate the current through the armature, which is used to calculate temperature ratings (as shown later). Design Tip: DC ...

a science that causes motors and machines to sometimes operate in unexpected ways. Over 30 years ago, AC drives were considered "new technology." If a company wanted to have reliable production, it ...
