摘要： PROBLEM TO BE SOLVED: To provide a compressor and an air conditioner preventing a piston from being locked in a cylinder by a freezing body. SOLUTION: A compressor operation control part 18 of a control device 20 stops the piston 2 in a high temperature region HR where temperature is relatively high and frost or ice is not easily formed on an inner circumference surface of the cylinder 1. Consequently, the piston 2 is prevented from being locked by the freezing body since the freezing body is not formed between the piston 2 and the high temperature region HR of the cylinder 1.

摘要： PROBLEM TO BE SOLVED: To provide a fan motor controller for suppressing the generation of an abnormal noise while protecting a power element by suppressing repetitive interruption and restoration of a signal to be outputted to a fan motor, and preventing reduction of an operable area of the fan motor. SOLUTION: In the fan motor controller, when an overcurrent of a brushless DC motor is detected, a signal to be outputted to the brushless DC motor is interrupted. After that, a modulation rate upper-limit value is set so that the modulation rate of a signal to be outputted to the brushless DC motor may be limited at a modulation rate within a range smaller than the modulation rate in detecting overcurrent (S52, S53). If the modulation rate upper-limit value is lower than the preset lower-limit value (No in S54), the lower-limit value is set as the modulation rate upper-limit value (S55).

摘要： PROBLEM TO BE SOLVED: To prevent the waveform of an integrated signal from being disturbed significantly by controlling the inverter output to have a zero vector waveform before a switching is made to an inverter mode. SOLUTION: In an integrator 1, a first neutral voltage VN obtained at the joint of stator windings 5a, 5b and 5c is applied to the non-inverted input terminal of an operational amplifier 1a while a second neutral voltage VM obtained at the joint of resistors 6a, 6b and 6c is applied to the inverted input terminal of the operational amplifier 1a. Consequently, the differential voltage VMN between both neutral voltages is integrated by the integrator 1 to produce an integrated signal ∫VMNdt. A rotational positron detection signal SINT is obtained from the integrated signal and an inverter gate waveform signal is produced based on the rotational position detection signal. An inverter 7 is controlled to produce an output having a zero vector waveform before a switching is made to inverter mode thus preventing the waveform of the integrated signal from being disturbed significantly.

摘要： PROBLEM TO BE SOLVED: To decrease the number of times of occurrence of dead time and to enlarge an operation area by setting smaller the carrier frequency of inverter in response to the increase in the voltage control factor. SOLUTION: When controlling an inverter 7 for driving a brushless DC motor 5 based on a voltage control factor preset and the rotational position of a rotor 5d of a brushless DC motor 5, the carrier frequency of the inverter 7 is set in response to the voltage control factor. Also, a threshold limit value of the carrier frequency is preset and the carrier frequency is gradually reduced until the carrier frequency reaches the threshold limit value. By doing this, the number of times of the occurrence of dead time can be reduced and the output voltage of the inverter can be increased, and the operation area of the brushless DC motor 5 can be enlarged. Also, the occurrence of troubles due to a sudden increase in the inverter output voltage is prevented, thereby stabilizing the operation of the brushless DC motor 5.
