Sensorless BLDC motor controller little power to the comfort of motor vehicles

Abstract

The article discusses low-power brushless motors and control modules that are used, among others, in trucks and buses. Also presented are methods of controlling brushless DC motors. The own low power controller was also implemented, enabling smooth start-up and control of the engine speed up to 3,000 revolutions and supply voltage up to 32V DC. This article also presents the results of the measurements of BLDC motor control used in automotive vehicles, mainly in trucks and buses.
