Resumen
Relevant researches have been growing on electric machine without mancal or bearing
and that is generally named bearingless motor or specifically, mancal motor. In this
paper it is made an introductory presentation about bearingless motor and its peripherical
devices with focus on the design and implementation of sensors and interfaces needed to
control rotor radial positioning and rotation of the machine. The signals from the machine
are conditioned in analogic inputs of DSP TMS320F2812 and used in the control
program.
This work has a purpose to elaborate and build a system with sensors and interfaces
suitable to the input and output of DSP TMS320F2812 to control a mancal motor, bearing
in mind the modularity, simplicity of circuits, low number of power used, good noise
imunity and good response frequency over 10 kHz. The system is tested at a modified
ordinary induction motor of 3,7 kVA to be used with a bearingless motor with divided
coil
