Bill Walton – a 7 foot tall anomaly
from the annals of basketball history
who wears tie-dye shirts, listens to the
Grateful Dead and, according to his
own outlandish proclamations, hasn’t
taken an indoor shower in 35 years – is
well-known for looking at average accomplishmentsand being overcome
with extreme fits of emotion.
The motors might be small, but the big-brain technology driving these electrical wonders was on full display at the 2014 Small Motor &
Motion Association Fall Technical Conference, convened November 4-6 in St. Louis, MO. SMMA, the manufacturing trade association (120 members
strong) that tends to the best interests of the electric motor
and motion control industries — including manufacturers, suppliers, users, consultants and universities — played gracious host to a wide array of presenters from an equally diverse range of sources — from academia to the federal government. Like gears, motors are most everywhere, as evidenced by SMMA’s membership (consumer-, public interest-, national defense- and commercial-oriented) demographic
which includes: appliance; transportation; medical equipment; office automation and computers; aerospace; and industrial automation. The association’s mission: To “serve as the principal voice of the electric motors and drives industry” and to provide a forum to “develop, collect and disseminate technical and management knowledge.”
With two armed conflicts underway impacting economic performance in Eastern Europe and the Middle East, we
continue our investment stance of “Buy on the Sound of Cannons — Selectively” — but readers of Power Transmission
Engineering should not be sanguine.
Geopolitics is beginning to exert significant pressure on several end markets: I specifically refer to oil price. West Texas Intermediate or WTI has dropped from its $95-105 trading
range in late spring to about $75 — about a (25%) drop despite
wo ongoing conflicts because of excess supply.
EDITORS’ NOTE: “The Applications of Bevel Gears” is the excerpted third chapter of Dr. Hermann Stadtfeld’s latest book — Gleason Bevel Gear Technology (The Gleason Works,
Rochester, New York, USA; All rights reserved. 2014; ISBN 978-0-615-96492-8.), which appears here unabridged through the kind graces of Dr. Stadtfeld and Gleason Corp. Future installments will appear exclusively in Power Transmission Engineering

He was out.
Nine years ago, Ross Rivard left the
coupling industry for the shimmering
new world of luxury automotive components at Lacks Enterprises, where he was immediately enveloped by platinum trim systems and chrome composite wheels. It was glitz and glam and as sparkly clean as the fresh-fromthe-dealership cars his products were embellished onto.
According to the Department
of Energy (DOE), more than
half of all electrical energy
consumed in the U.S. is used
by electric motors. To address
this, several years ago, the DOE conducted
a technical study as to what
could be done to raise the efficiency
levels of “small” motors. After years
of study and litigation, the Small Motor Rule (SMR) was passed that covers two-digit NEMA frame single- and three-phase ¼ through 3 horsepower
motors in open enclosures.
In the Stott household, we love math.
Well, maybe not everyone in my household loves it equally, but since they were in kindergarten, whenever one of my children asked me for help with math homework, my reply has been an instant and cheerful “We love math!”
