These machines have often been  considered in the literature, under one common assumption ¿ ideal placement of the sensors, which  is often not the case, especially for low-precision  motors. This thesis is composed of three manuscripts which  investigate the unbalance of Hall sensors and propose methods to eliminate its adverse effects.  The studies presented here show that misalignment of Hall sensors leads to unbalanced  operation of the inverter and motor phases, which in turn results in increased low-frequency  harmonics in torque ripple, possible acoustic noise, and degradation of the overall drive  performance.  The presented research considers a typical  industrial brushless dc motor and includes measurements, detailed models and hardware  experiments to validate the analysis. The proposed averaging approach is shown to achieve performance  characteristics very close to those of a motor with perfectly balanced Hall sensors.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844326611\"\u003e\u003ch3\u003eWITH UNBALANCED HALL SENSORS\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844326611","offer_id":39495974846557,"sku":"9783844326611","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/53e6f821-b74d-48c1-ba37-ff8b6c68c5f9.jpg?v=1773383349","url":"https:\/\/shop.autorenwelt.de\/products\/analysis-of-brushless-dc-motors-von-nikolay-samoylenko","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
