Brushless DC Motors ? More Knowledge Means Better Results

On Thursday, March 25, 2010 the IEEE Consultants' Network of Northern NJ (www.TechnologyOnTap.org) will present Steven R. Garfinkel, Principal of Ellipsah LLC, who will discuss how BLDC motors are constructed, their performance and how to select them.


Brushless DC motors are used in high performance servo systems. They are capable of high power output in a given size, making them the motor of choice for weight- or size-sensitive applications. When properly applied, they are enormously robust.

This discussion will cover the basics of the construction of BLDC motors. Without resorting to heavy math, the basics of their design will be presented, to provide attendees with a more complete understanding of how they work and what features to look for. Users of BLDC motors will be in a better position to ensure they get a motor that will work from their supplier.

The primary components of a BLDC motor are the magnets, laminations, insulation, commutation sensor and windings. Each will be briefly discussed. A systematic approach to the selection of a BLDC motor for a specific application will be presented. If you have any questions about how BLDC motor work, you will find the answers in this presentation.

Steven Garfinkel received his B.Sc. and M.Eng. in Electrical Engineering from Rensselaer Polytechnic Institute in Troy, New York. He designed autopilots, flight control actuators, rescue hoists, cargo winches and industrial tools over his career of more than twenty five years. His company, Ellipsah LLC, provides complete servo system design services, including custom motors and controllers. Steven can be reached at sgarfinkel@ellipsah.com or at (973) 432-7401

Founded in 1992, the IEEE Consultants Network of Northern NJ encourages and promotes the use of independent technical consultants by business and industry.
