摘要： PROBLEM TO BE SOLVED: To provide a motor controller, and a refrigerator and an electrical machine using the same, capable of suppressing the generation of electric current surge and speed fluctuation for smoothly switching over the energization mode.SOLUTION: An electric voltage applied to a motor is arranged to change continuously before and after switching between a 180° energization mode and a 120°energization mode. Because the electric voltage applied to the motor is not rapidly changed but is continuously changed before and after switching the energization mode for an electric power inverter circuit, electric current surge and rapid speed fluctuation can be suppressed.

The end of the commutation overlapping period of the inverter is determined from the output value of the primary delay filter device, and position estimation is performed by determining whether a terminal voltage in the non-conducting phase of the permanent magnet motor 2 has exceeded a conduction mode switching threshold after the end of the commutation overlapping period. In this way, the non-conducting phase of the inverter 1 is set from the result of the position estimation.
