Electrician's Technical Reference: Motors

Rating:
Summary: An adequate treatment of the subject
Review: I found this to be a readable, thorough text that adequately covers the subject. A fair number of pages at the end are devoted to reference material -- dimension tables and tables of typical values for real-world motors -- which I found valuable. Criticisms include proofreading - several equations substitute the number "12" for "I squared" which made for a real headscratcher until I figured it out. The line drawings that illustrate the text were apparently supplied by Siemens as this company's name appears prominently on them. This seems parochial to me and should have been edited out, or other illustrations used. I thought that the treatment of phase relationships and rotating magnetic fields was less than rigorous, taking a phenomenological approach rather than an analytical one. It would appear that any material requiring a knowledge of trig and calculus had been stripped out, which is unfortunate. Still, not a bad text overall.
