Porovnání vlastností senzorového a bezsenzorového řízení 3 fázového BLDC motoru / Comparison of sensor and sensorless control of 3-phase BLDC motor

Drápal, Michal January 2020 (has links)
The diploma thesis is focused on comparison of sensored and sensorless control of 3phase BLDC motor. This diploma thesis was compiled with engineers from Honeywell, spol. s r. o. and NXP Semiconductors comapny. Theoretical part of the diploma thesis is describing princip of function BLDC motor and different methods of control. The testing of NXP sensored and sensorless application is done in the practical part. Regarding to the fact, that applications were provided by NXP, furthemore the diploma thesis additionally contains a state machine using sensorless application from NXP. Finally, the author is evaluating a cooperation with NXP company and he thinks about next possible cooperation.

Univerzální řídicí jednotka pro BLDC motory / Universal BLDC motor controller

Pijáček, Ondřej January 2016 (has links)
This thesis describes the design of universal control unit for BLDC motor powered from airplane power distribution system of 28 V capable of driving motor up to 10 A. The maximal engine power is about 250 W. Important prerequisite is possibility of driving various motor size without needs of changing wiring board using only the configuration in the auxiliary memory unit. To control different motors is enough one unit with one program without any way to interfere to the unit itself.
