The inverters used to drive the windings alone were prohibitive in cost and in size. But without a sensor to detect the rotation angle of the permanent magnet in the rotor, it's impossible to know which phases to energize with a given polarity. Brushless-dc (BLDC) motors possess many desirable traits that help them find their way into growing numbers of medical applications every year. Sensorless brushless-dc-drives have evolved to a point where they have wide appeal within the medical-design community. One reason: A life to a 3 ac motor. Others have dedicated motor control a bit switched around in a brushless motor. Overall cost kept the BLDC option off of the table. Krishnan, “Modeling, Simulation and Analysis of Permanent – Magnet Motor Drives, Part 2: The Brushless DC Motor Drive, “ IEEE Trans, Ind. The motor in direct drive machines is typically a permanent magnet synchronous motor (brushless DC motor) versus an induction motor. Some have the right kind of analog to digital converter controls allowing synchronous sampling of an analog voltage. In a permanent magnet brushless DC motor, the magnets are in the rotor and the switched, or commutated, windings are in the stator.
