Claims

[Scope of utility model registration request]

A non-commutated motor that uses a permanent magnet as a rotor and continues rotation by switching the armature winding current on the stator side according to the magnetic pole position of the rotor, and is used as a motor for air conditioners. In the secondary motor, there is a voltage detector that detects the motor voltage, an electric particle detector that detects the armature current, an integrator that integrates the voltage output of the voltage detector, and a current output that integrates the current output of the current detector. An integrator and a proportional coefficient unit that multiply the child winding resistance constant, a proportional coefficient unit that also multiplies the current output by the armature winding inductance constant, and a proportional coefficient unit that multiplies the output of the voltage integrator. An addition/subtraction circuit that subtracts the output, a comparator that converts the rotating field pole magnetic flux output from this addition/subtraction circuit into a rectangular waveform, and an inverter with a 120° width and 60° phase difference that performs logical operations on the three-phase outputs of each phase comparator. A non-commutator motor for an air conditioner is comprised of a logic circuit that obtains six series of rectangular waveforms that are six transistor-based signals, and a non-commutator motor for an air conditioner.
