Abstract
Control of permanent magnet synchronous machines (PMSMs) requires rotor position measurement/estimation, as well as the magnet polarity detection for startup of the machine. The rotor position of PMSMs is typically measured using a speed/position sensor (e.g. an encoder), while the magnet polarity is commonly measured using digital hall-effect sensors. Since simplifying the system can help improve reliability and reduce the cost associated with the measurements, the use of low cost analog hall-effect sensors for estimation of the PM position and polarity for control of PMSMs drives is evaluated in this paper. Experimental results performed on a 7.5 kW motor confirm that analog hall-effect sensors can replace both speed/position sensors and digital hall-effect sensors, while maintaining adequate performance of the drive at lower cost.
