Switch reluctance machine rotor angular position and rotation speed detection device and method

Abstract: The invention relates to a device for detecting the angular position and the speed of the switch magnetic resistance motor and method, comprising a rotary encoder and a signal processing circuit mounted in the motor and fixed on a support plate, wherein the rotary encoder is connected with the main axis of the motor. The rotary encoder collects and transfers the angular position signals of the rotator to the encoder signal pretreating unit of the signal processing circuit. The encoder signal pretreating unit converts the output signal of the encoder into the signal capable for being received by the microprocessor unit. The microprocessor unit processes the angular position signals and calculates the speed of the motor. The communication unit sends the angular position signals and speed signals by serial communication bus. The connection line of the said device with the outside is simple and the antijamming capability is strong. The device device for detecting the angular position and the speed of the switch magnetic resistance motor is suitable for long distance transmission with high resolution, easy operation, small error and no zero setting by manpower.

An Angular Displacement Sensor Based on Microwave Transversal Signal Interference Principle

Abstract: A novel rotational angle microwave sensor with a high dynamic range and sensitivity for detecting angular displacement is presented. It exploits the spectral separation between two notch frequencies or transmission zeros that are generated in its transfer function, and whose value varies as a function of the rotation angle to be measured. The sensor is based on a bi-path transversal-signal-interference (TSI) circuit configuration that is implemented on microstrip technology, where a rotor comprised of an open-circuit-ended stub is loaded onto a stator of this transversal circuit with equal-length electrical paths. The mechanical rotation of the rotor changes the contact point of the open-circuit-ended line to the stator, thus effectively modifying one of the overall paths of the stator and, hence, the inter-transmission-zero separation. Design guidelines for the synthesis of the proposed rotation sensor with a specified dynamic range and sensitivity are provided. Furthermore, a proof-of-concept microstrip-substrate-based prototype with an angular rotation range of 180° is developed at 920 MHz and tested to validate this approach experimentally.

Generation of charged particle vortex waves

Abstract: A device is arranged for imparting an orbital angular momentum to a charged particle wave propagating along an axis in a charged particle beam generating apparatus. The device includes a first conductive element comprising a plurality of angularly spaced electrical conductors arranged around the axis, and a second conductive element. The first and second conductive elements are spaced apart along the direction of the axis, and are adapted for transmitting a charged particle wave propagating along the axis. A connecting means is adapted for supplying an electrical potential to the plurality of angularly spaced electrical conductors for inducing an angular gradient of the phase of the charged particle wave when transmitted along the axis, in which the projection along the axis of the electrical potential varies as a function of an angular position with respect to the axis.
