휴대용 제품에 적용 가능한 초고속 모터와 센서리스 인버터 시스템 설계 및 제어

Abstract

Portable products that use high-speed motors, such as vacuum cleaners and hair dryers, use battery power as input power. The portable batteries, the most widely used DC battery of the 18650 model is used. Most of the portable products, it is necessary to develop technologies to reduce the size and weight of batteries, motors, and controllers. In this paper to solve this problem, the advantages of portable products are by reducing the size and weight of the product through the design and application of a high-speed motor that can operate at high speed and use an appropriate level of the battery. In addition, it is possible to secure overall product competitiveness by applying a converter that can operate a high-speed motor and sensorless inverter technology to reduce material costs.
