Electric motors in the woodshop
Synopsis: Electrical engineer Edward J. Cowern explains how electric motors work, why they might stop working, and how you can intelligently choose new ones to use as replacements or incorporate in the machines you build. His information is designed to help you make sensible, safe decisions when choosing, connecting, and operating electric motors in your workshop. Cowern discusses various motor types, enclosure types, frame size and mounting, and motor controls. He also covers maintenance and troubleshooting. Side information tackles the meaning of horsepower and the mysteries of horsepower rating standards.
There was a time not too long ago when a woodworker had to open a sluice gate to a waterwheel or stoke the fire beneath a steam engine’s boiler before any powered machinery in the shop could be operated. Nowadays, the relative luxury of just flipping a switch makes electric motors an essential part of the woodshop.
