Maxon DC tacho, encoders and resolvers are mounted to motors with through shafts for reasons of precision and resonance. Several varieties of sensors are available.
Digital Magneto-resistant (MR) Encoder: In an MR-encoder, the multipole magnetic disc mounted on the motor shaft produces a sine-wave voltage variation in the MR sensor. The typical encoder signals are created through interpolation and electronic signal refinement.
Magnetic principle with Hall sensors: Under the magnetic principle, a small multipole permanent magnet sits on the motor shaft. The changes in magnetic flux are recorded by Hall sensors and fed into the electronics as channel A and B.
Optical Encoder signals: These encoders provide a simple square signal for further processing in the control system. It\'s pulses can be counted for exact positioning or determining speed. Channels A and B pick up phase shifted signals, which are compared with one another to determine the rotation direction. A "home" pulse (index channel I) then provides zero crossing and is used as a reference point for precise determination of rotation angle. The line driver output produces complementary signals A, B, I which help to eliminate any interference and improve signal quality on long signal lines.
DC Tacho: In principle every maxon DC motor can be used as a DC tacho. For motor / tacho combinations, we offer a DC tachometer, whereby the tacho rotor is mounted directly on the motor shaft.
Resolver: The resolver is mounted on the motor\'s through shaft and adjusted according to the magnetic field of the motor rotor. The resolver has a rotating primary coil (rotor) and two secondary coils (stator) offset by 90°. An alternating current connected to the primary coil is transferred to the two secondary coils.
