摘要： There is provided an electric compressor that can protect a component to be protected from heat damage according to a capability of the component. The electric compressor 10 includes a compression mechanism 11, an electric motor 12 that drives the compression mechanism 11, and a control portion 13 that controls to drive the electric motor 12, incorporated into a single casing, and further includes a temperature detector 14 that detects a temperature of one or more components that constitute one or both of the control portion 13 and the electric motor 12, and a current detector 15 that detects a current flowing through the component. When the temperature detected by the temperature detector 14 is a temperature Td, the current detected by the current detector 15 when the temperature detector 14 detects the temperature Td is a current Id, and a current corresponding to the temperature Td at a temperature characteristic relating to the current specific to the component is a current Ia(Td), the control portion 13 stops driving the electric motor 12 on the basis of a result of comparison between Ia(Td) and Id.

摘要： An electric compressor controller includes a compressor (11) that compresses refrigerant of an air conditioning system; a motor (12) that drives the compressor; an inverter (13) that selectively control switching elements (TR1-TR6) based on PWM pulse signals to supply drive power to the motor (12) and heats the refrigerant by heat generated due to switching of the switching elements (TR1-TR6) during a heating operation; temperature detectors (134) each detects junction temperature of each of the switching elements; a drive controller (14,131) that supplies the pulse signals to the inverter (13) to control the inverter; and a slope varying unit (133) that variably controls precipitous degree of rising/falling slope waveforms of the pulse signals based on the junction temperature detected by the temperature detectors. According to the electric compressor controller, efficiency for heating refrigerant is improved, so that its own heating ability is improved.

摘要： A thermally-actuated switch (1), comprising a switch body (2) having a metallic pressure-tight sealed container (4) and a contact mechanism installed in the air-tight sealed container (4) and a holder (3) having a base (3A) with an installation surface (3L) for an electric motor (10) to fit the motor to a coil end (11) and a holding part (3B) installed on the surface of the base opposite to the installation surface and holding the switch body (2), wherein the base is formed sufficiently large so that the switch body held on the holding part is not extended from the base, whereby a conductive heat and radiation heat from the coil end can be prevented from directly reaching the switch body when the thermally-actuated switch is fitted to the coil end.

摘要： A motor pump (10) includes a pump head (22) for pressurizing a fluid and an electric motor for driving the pump head. Within the pump head, radial forces produced in two symmetrical pumping zones are balanced against each other to reduce stress and increase efficiency. High pressure fluid exits the pump and follow a flowpath through the motor air gap, through an end bearing carrying a distal end of a hollow pump rotor shaft, and returning to the pump head by way of the hollow rotor shaft (44) . The motor rotor shaft (44) is axially movable with respect to the pump head, which effectively floats the motor rotor in high pressure fluid. A motor stator barrier (56) can inhibits fluid flow into the motor stator (90) , and a rotor barrier (112) can inhibits fluid flow into the motor rotor. The rotor barrier can is efficiently attached to the rotor shaft in such a way as to stiffen the shaft and increase its bending resistance. The walls of the stator barrier can are thin and expand under fluid pressure to make contact with and find structural support from the stator laminations and motor endshield. Overheat conditions within the motor, as well as the pump head, are detected by positioning a heat sensing switch (130) within the motor adjacent the pump head (22) to shut down the motor (14) when an overheat condition is detected.

摘要： A thermally responsive valve assembly (134) for scroll motor-compressor high temperature protection, which causes a high-side to low-side leak when excessive discharge gas temperatures are encountered, thereby causing the motor protector (35) to trip and de-energize the motor. The valve assembly (134) includes means for ducting (200) the excessive temperature discharge gas to the lower portion of the motor/compressor shell (10) to the motor to circulate the high temperature gas throughout the motor cavity. The excessive temperature discharge gas heats the motor stator (20) and windings (32) which will in turn cause the motor protector (35) to trip and de-energize the motor.
