In the armature, an electromotive force is created by the relative motion of the armature and the field. When the machine or motor is used as a motor, this EMF opposes the armature current, and the armature converts electrical power to mechanical power in the form of torque, and transfers it via the shaft. When the machine is used as a ...
A growler is an electrical device primarily used for testing a motor for shorted coils. A growler consists of a coil of wire wrapped around an iron core and connected to a source of alternating current.

Like most slot car motors, the Aurora pancakes ran on low voltage direct current. The term 'pancake' is also loosely used to refer to a car or chassis which has such a motor. Common Slot Car Motor Arrangements. Common Slot Car Motor Arrangements. The Pancake motor (far right) is seen end-on, with the shaft pointing toward the reader.
The Electric Building is an 18-story Art Deco and Spanish Renaissance styled building located in downtown Fort Worth, Texas. The building currently houses apartments with the ground floor used for retail stores .
The DC motor was the mainstay of electric traction drives on both electric and diesel-electric locomotives, street-cars/trams and diesel electric drilling rigs for many years. The introduction of DC motors and an electrical grid system to run machinery starting in the 1870s started a new second Industrial Revolution .
