    摘要： A control switch incorporates a solid state transducer, a strain gauge. The transducer responds to a local environmental condition, such as fluid level, or pressure and exhibits a parameter change which can be detected as an electrical output. Control circuits coupled to the transducer can sense the parameter change and switch a source of electrical energy to a load in response thereto.

    摘要： The present invention includes: an electrolytic capacitor that smoothes a rectified voltage to a direct voltage; an inverter circuit that generates an alternating voltage from the direct voltage, to drive an electric motor; a controlling device that controls drive of switching elements included in the inverter circuit; and a temperature measuring device that measures a temperature of the electrolytic capacitor, to output the measured temperature to the controlling device, in which, when the temperature obtained by the temperature measuring device is lower than a predetermined target temperature, the controlling device supplies the electric motor with a current which is restricted so that a ripple voltage of the direct voltage falls within an allowable range, before starting a normal operation of the electric motor, so that the temperature of the electrolytic capacitor is raised to the target temperature. Thus, the electrolytic capacitor can be used even in a lower-temperature environment.

    摘要： A method of starting a brushless motor that includes a rotor, a stator having at least one phase winding, and a rotor-position sensor. The method involves exciting the winding and sensing a signal output by the sensor. If an edge of the signal is sensed during a first period, the winding is commutated in response to the edge. Otherwise, the method involves commutating the winding at the end of the first period, sensing the signal, and commutating the winding in response to a second of two edges of the signal sensed during a second period. Additionally, a control system that implements the method, and a motor assembly that incorporates the brushless motor and the control system.

    摘要： A system and method for starting and regulating a wound rotor motor especially during the period between inactivity and a speed determined by the voltage ratings of the drive system. In a first embodiment, a starting resistor and a starting bypass contactor are connected between the rotor of the motor and a low voltage source inverter. In an alternative embodiment, the arrangement of the first embodiment is altered by connecting a shorting contactor on one side to the junction of the voltage source inverter, the starting resistor and the starting bypass contactor so as to be short circuited on the opposite side of the shorting contactor.
