Resolver interface comparison

Abstract

For control of BLDC motor EMRAX 228 with a peak power of 109 kW, it is necessary to know the exact position in time. This electric motor is used as a drive unit for an electric quad bike manufactured at the Department of Mechatronics and Electronics. In this article we will analyze the position sensing of a BLDC motor with an implemented resolver without an external resolver sensor and with a comparison of two types of resolver sensors PGA411-Q1 and AD2S1210.
