Evaluation of Hall-sensors for motor control in high precision applications for aircraft
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
A functioning prototype test motor with Hall-sensor feedback has been built, and the test results show that the motor performance in terms of speed ripple is well within the specified demands. The temperature demands however, have not been fully met. The minimum operating temperature of the sensor was specified to -55◦C by Saab, and the sensors found on the market has a minimum operating temperature of -40◦C. There was also an operation error, the reason of which could either be failure of the drive unit to deliver enough current, or the stator magnetic field strength being too strong for the sensors to reliably detect the rotor magnets when a sufficiently strong current is run through the stator windings. For the purpose of investigating this error it is proposed to conduct tests with a drive unit that can deliver currents over 5 A.
