• POSITION SENSORS

There are several ways to sense brushless rotor position. Rotor position sensing is necessary so the stator winding excitation can be controlled to keep the electro-magnetic field in leading quadrature with respect to the rotor field. These methods fall into three categories: photo-electronic, electromagnetic, and magnetic.

PHOTO ELECTRONIC

A set of photo-transistors and LEDs are coupled across a shutter which is keyed to the rotor and has windows in the proper pattern to control the phase excitation. If a shaft angle encoder is required in the system for normal shaft position sensing, a separate pattern track can be included on the disk for motor commutation. The out-put of an absolute encoder can also be used in a sine cosine ROM or as input to a digital comparator to develop the commutation waveform.

ELECTROMAGNETIC

Electromagnetic sensors use a soft iron target and a set of wound coils. Changes in the coil inductance are sensed and decoded to verify rotor position. Eddy current devices using metallic targets can also be used in the same manner. Brushless resolver are commonly used in sine cosine systems as the source of the phase quadrature waveform.

• MAGNETIC

Hall effect sensors, magneto-resistors, or magneto-diodes are used in magnetic sensors. These devices work directly off of the rotor poles so that the alignment of the sensors can be accomplished during the manufacture of the stator. They become a part of the stator assembly so that the user need only install the rotor to have an aligned system.
