    摘要: An inverter-integrated electric compressor has a control device. The control device estimates a compressor suction pressure based on the temperature of the power element of the inverter, or directly measures the compressor suction pressure by a sensor, or estimates the compressor suction pressure based on a compressor suction temperature or on a compressor housing temperature. Further, the control device calculates a motor torque based on a motor rotational speed, a motor phase current, and a motor phase voltage, estimates a compressor discharge pressure based on the compressor suction pressure and the motor torque, and estimates a compressor discharge temperature based on the compressor suction pressure and the compressor discharge pressure. The electric compressor has a discharge temperature detection device in place of a conventional thermal protector.

The control device estimates a compressor suction pressure based on the temperature of the power element of the inverter, or directly measures the compressor suction pressure by a sensor, or estimates the compressor suction pressure based on a compressor suction temperature or on a compressor housing temperature. Further, the control device calculates a motor torque based on a motor rotational speed, a motor phase current, and a motor phase voltage, estimates a compressor discharge pressure based on the compressor suction pressure and the motor torque, and estimates a compressor discharge temperature based on the compressor suction pressure and the compressor discharge pressure. An electric compressor having a discharge temperature detection means in place of a conventional thermal protector can be realized.

    摘要: A motor-driven compressor includes a motor and a compression portion for compressing a refrigerant. The motor-driven compressor comprises an input terminal for the motor and a drive circuit for controlling a rotation speed of the motor. The input terminal of the motor passes through an opening formed through a wall of a refrigerant suction route, whereby the input terminal is secured to the wall, and extends beyond the wall. The drive circuit controls the rotation speed of the motor and has an output connector. The output connector of the drive circuit is connected directly to the input terminal to secure the drive circuit to the wall. The direct connection eliminates a need for a wire connection between the output connector and the input terminal. Moreover, methods of assembling motor-driven compressors are disclosed.

    摘要: A device executing a start-up control method for an electric scroll compressor has a thermistor (18) and a pressure sensor (20) which, prior to the start-up of the scroll compression unit, detect temperature and pressure of a suction refrigerant introduced into the compression unit (2), and a controller (10) for controlling driving of a motor (4) of the compression unit (2) at the start-up of the compressor. The controller (10) determines at the start-up of the compressor whether or not a liquid refrigerant exists in the compression unit (2) on the basis of the detected temperature and pressure; selects either a normal start-up mode or a liquid-discharge mode in which the rotational speed of the motor (4) is regulated to be lower than in the normal start-up mode, according to the determination result; and controls the start-up of the compression unit (2) through the motor (4) according to the selected mode.

    摘要: Provided is a terminal device for an electric compressor including: a partition wall arranged between a container part for a compression mechanism drive motor present with a lubricant-containing fluid to be compressed and a circuit part for supplying power to the motor; and a power supply terminal member hermetically extending through the partition wall so as to supply power to the motor. An electric communication portion of the terminal member extending between the two parts is covered with insulating varnish. Even when polyalkylene glycol-based oil is used as the lubricant-containing fluid to be compressed, it is possible to realize an electric compressor terminal device with a simple structure at a low cost which can exhibit a sufficiently high insulation performance.
