| 361022000 | Compressor protective circuits | 6 |
| 20120033334 | POWER CIRCUIT, AND COMPUTER-READABLE RECORDING MEDIUM STORING A CONTROL PROGRAM FOR POWER CIRCUITS - When an abnormality occurs in a refrigeration cycle, the inverter motor provided in the air conditioner is stopped reliably and contacts of the main relay are prevented from degradation and fusion. A power circuit | 02-09-2012 |
| 20120236441 | COMPRESSOR FOR AN AIR-CONDITIONER WITH A MOTOR PROTECTOR AND AN AIR-CONDITIONER - The present disclosure includes a compressor for use with an air-conditioner. The compressor includes a motor having a stator and a rotor. A compressing portion intakes gas, compresses gas and discharges gas. The compressor includes a protector located near the motor. The protector is connected in series to the circuit of the motor stator coil. The protector has a temperature sensitive element that trips the protector in response to the temperature sensitive element being heated to a predetermined drive temperature. A thermal resistance heater connects in parallel to the temperature sensitive element. The compressor can be includes with an air-conditioner, having an evaporator, a condenser, a throttling member and the compressor. | 09-20-2012 |
| 20120327539 | ASSEMBLY OF ELECTRIC MOTOR STARTER COMPONENTS - Techniques disclosed herein include systems and methods for assembly of electric motor starter connecting packages that enable increased automation and reduced assembly via top-down assembly of circuit components, thereby allowing robotic placement, connection, and securing of circuit components. The connecting package can include an electric motor starter, with optional overload protector, packaged as one unit. The motor starter can include an electrical circuit containing a triac, current transformer, Positive Temperature Coefficient (PTC) element, resistor, and a capacitor. A cover and base of the connecting package enclose and firmly secure connected circuit elements without needing a circuit board or filler material. The device design enables quick testing of the motor starter circuit and circuit elements after being enclosed by the housing. | 12-27-2012 |
| 20140168826 | ACTUATING MODULE FOR AN ELECTRIC VACUUM PUMP - An electric vacuum pump actuating module for boosting the braking force of a motor vehicle, including a main controller and a driver circuit for operating the electric vacuum pump. The driver circuit includes a first and a second switch. The first switch switches a supply voltage above a predefined voltage level of an operating voltage of the vacuum pump. The second switch switches a supply voltage below the voltage level of the vacuum pump. The main controller controls the first switch by first control signals and the second switch by second control signals. The actuating module determines a state of the electric vacuum pump as a first piece of information based on a first response of the electric vacuum pump resulting from the first or second control signals. The actuating module assesses the state of the electric vacuum pump as error-free or erroneous operation of the electric vacuum pump. | 06-19-2014 |
| 20150029619 | POWER SUPPLY CONTROL DEVICE - A power supply control device includes an inverter having plural switching elements, an inverter controller that controls the inverter, a device power supply that generates a first power supplied to the inverter controller, a detector that detects whether there is an abnormality relating to the compressor, and a power supply controller. The inverter generates drive voltages usable to drive a compressor motor that is a drive source of a compressor as a result of the switching elements switching on or off, and outputs the drive voltages to the compressor motor. The power supply controller stops generation of the first power by the device power supply to thereby stop the control of the inverter controller in a case where there is an abnormality relating to the compressor. | 01-29-2015 |
| 20160079020 | ENCAPSULATION OF COMPONENTS AND A LOW ENERGY CIRCUIT FOR HAZARDOUS LOCATIONS - Embodiments of the disclosure provide an encapsulated compressor overload, an encapsulated compressor relay start, an encapsulated head pressure control switch and a wiring diagram for a circuit for air conditioning units which prevent gases from being ignited by means of encapsulating sparking components, use of solid-state switching devices, and/or wiring circuits in such a way that open contacts do not contain enough energy to produce a spark capable of igniting the atmosphere. | 03-17-2016 |
