COMPRESSOR AND DEVICE ON WHICH COMPRESSOR IS MOUNTED

PROBLEM TO BE SOLVED: To provide a compressor that is capable of reducing power consumption, and a device that has the compressor.SOLUTION: This compressor includes a motor having a rotor and a stator, and being capable of performing driving by a 120-degree energization method. When stopping the compressor, a rotor position during a stop is estimated on the basis of information about a magnetic saturation electromotive voltage, and rotor position information during the stop is stored. When starting the compressor, an initial operation condition including a three-phase coil energization pattern is determined by using the stop position information of the rotor.SELECTED DRAWING: Figure 3 【課題】消費電力量を低減可能な圧縮機及び圧縮機を有する機器を提供する。【解決手段】回転子と、固定子と、を有し、１２０度通電方式による駆動が可能なモータを有する圧縮機であって、圧縮機を停止させる場合、磁気飽和起電圧の情報に基づいて、停止時のロータ位置を推定し、停止時のロータ位置情報を保存する。圧縮機を起動させる場合、回転子の停止位置情報を利用して３相コイルの通電パターンを含む運転初期条件を決定する。【選択図】図３
