Abstract: A motor driving apparatus including a motor including a stator and a rotor rotating in the stator, an inverter configured to supply a driving voltage to a stator coil wound on the stator so as to rotate the rotor, and a control unit configured to, when a target command value is received, change a predetermined reference start-up time point to a start-up time point corresponding to an electrical angle position of the rotor in correspondence with the target command value per rotation of the rotor and to control the inverter to supply the driving voltage at the start-up time point.
Abstract translation: 一种电动机驱动装置，包括：电动机，其包括定子和在所述定子中旋转的转子;反相器，被配置为向缠绕在所述定子上的定子线圈提供驱动电压以使所述转子旋转;以及控制单元， 接收目标指令值，将预定的基准起动时间点改变为对应于转子的每个旋转目标指令值对应于转子的电气角度位置的启动时间点，并控制逆变器供应 启动时间点的驱动电压。
