Engineers looking for solutions to their motor control
dilemmas could get a boost from a series of workshops held by Microchip Technology Inc. over the next
three months.
The motor control workshops,
scheduled in locales around the U.S.
and in Canada
through mid-June, are aimed at helping engineers who have impending projects
involving brushless DC motors or permanent magnet synchronous (PMS) motors.
"A lot of
engineers have projects coming due and these days there's pressure on them to
get things out faster," says Steve Marsh, strategic marketing manager for
Microchip's High Performance Microcontroller Division. "The engineers who have
less time and have a deadline approaching are probably the ones who will get
the most out of this."
Brushless DC
(BLDC) workshops will be held in Toronto,
Boston, Cleveland, Baltimore, San Jose and Detroit. The workshops,
aimed at sensorless BLDC control, feature the sensorless majority function
algorithm, which digitally filters the back electromotive force generated by
the non-commuted windings to calculate rotor position, eliminating the need for
comparators and position sensors.
"Quite a
few engineers have only dealt with stepper motors, where the control scheme can
be much simpler," Marsh says. "We're seeing people who want to step into
brushless DC motors or PMS motors."
Marsh says the
benefits of the workshops could extend beyond near-term projects. "If you
happen to know PMS motors, or field-oriented control, it might just make you
more marketable, especially in this economic environment."
