摘要： Certain circuit faults in a phase of a multi-pole, switched reluctance, rotary electrical machine are detected; and the machine is selectively operated with a detected circuit fault when the nature of the fault permits continued operation of the phase and the operation of the phase is desirable. The fault may be one of certain short or open circuits in which at least one of the two current controlling electronic switches is operable to control phase current within predetermined limits. In the continued operation when a fault is detected, (1) the phase current is switched off earlier than it would be in the absence of the fault and/or (2) the maximum phase current is reduced compared with that permitted in the absence of the fault; and either or both of these modifications may be a function of motor speed. If the circuit fault adversely affects current control by an electronic switch normally controlling current level, another electronic switch is substituted for current control.

摘要： In one embodiment, a sensor assembly has a magnetostrictive (MS) element and a sensor housing defining at least one active wall. A sensor channel is disposed on a first side of the active wall, with the MS element being disposed in the sensor channel and closely received therein. A fluid is on a second side of the active wall, and the active wall is the wall through which stress from pressure of the fluid causes stress on the MS element. The sensor channel defines an axis parallel to the active wall, and the MS element is positioned adjacent the active wall by sliding the MS element into an end of the sensor channel in a direction parallel to the active wall.

摘要： This invention relates to a load sensor comprising a member composed of electrically conductive magnetostrictive material. The member is a uniform and continuous distribution of wire or strip material abutting itself between opposite ends. The magnetostrictive material is annealed and abutting portions of the member are spaced apart from one another using insulation incorporating microspheres. Terminals at different portions of the member allow the member to be electrically connected in a circuit for measuring an impedance of the member. Stress applied along an axis of the member causes a change in the member's permeability that is measurable as a change in impedance of the sensor. The configuration of the sensor can be described as coil shaped or accordion shaped. The wire or strip material comprising the sensor comprise a variety of shapes. Insulation comprises a high strength adhesive filled with high strength ceramic microspheres. A method is also taught in the present application to fabricate the load sensor of the present invention.
