摘要： A method and system for measuring rotor position or velocity in an electric motor disposed in hydraulic fluid. The system comprises a contactless position sensor that measures electric motor rotor via magnetic, optical, or other means through a diaphragm that is permeable to the sensing means but impervious to the hydraulic fluid. An electronic sensor is positioned outside the operating fluid, whereas the motor is located in the fluid volume.

摘要： An active suspension system for a truck cabin that actively responds to and mitigates external force inputs between the truck chassis and the cabin. The system greatly reduces pitch, roll, and heave motions that lead to operator discomfort. The assembly is comprised of two or more self-contained actuators that respond to commands from an electronic controller. The controller commands the actuators based on feedback from one or more sensors on the cabin and/or chassis.

摘要： A distributed active suspension control system is provided. The control system is based on a distributed, processor-based controller that is coupled to an electronic suspension actuator. The controller processes sensor data at the distributed node, making processing decisions for the wheel actuator it is associated with. Concurrently, multiple distributed controllers on a common network communicate such that vehicle-level control (such as roll mitigation) may be achieved. Local processing at the distributed controller has the advantage of reducing latency and response time to localized sensing and events, while also reducing the processing load and cost requirements of a central node. The topology of the distributed active suspension controller contained herein has been designed to respond to fault modes with fault-safe mechanisms that prevent node-level failure from propagating to system-level fault. Systems, algorithms, and methods for accomplishing this distributed and fault-safe processing are disclosed.

摘要： Control over an electric motor is especially critical in large drilling rigs and a means of accurately and quickly measuring the speed of the rotor of an electric motor and correlating that information with other real-time information has been hampered by the failure of the prior art to attach optical encoders to electric motors with precision. The present device attaches to arbor of a cap on the end of the rotor which provides a centralized and sealed shaft extending through a covering plate on the end of the motor and directly attaching to an optical encoder.

摘要： In a method for the determination of a current initial rotational position of a rotor and in an arrangement for carrying out same, an incremental position encoder outputs an output signal. The output signal is produced by superposition of a chronologically random and systematically fluctuating signal interference on a basic signal, and composed of at least two component signals which change periodically in accordance with the rotational position of the rotor and are in a fixed angular relationship to one another. To determine the position, the output signal is used exclusively. The current initial rotational position of the rotor relative to a reference initial rotational position is determined by comparing the time profile of the portion of the systematically fluctuating signal interference of a current measured value sequence of the signal and the measured values of a signal sequence acquired starting from the reference initial rotational position.

摘要： A brushless DC motor is provided and includes: a stator assembly; a rotor assembly including a sleeve; a case assembly; and a circuit board assembly which has an electronic component mounted thereon. The case assembly is provided with an opening, the electronic component passes through the opening so as to protrude inside the case assembly, and a groove is formed at an axial end of the sleeve of the rotor assembly in order to prevent the electronic component from making contact with any part of the rotor assembly. Thus, the axial dimension of the brushless DC motor that includes the electronic component disposed to protrude inside the case assembly can be successfully reduced in such a manner that the electronic component is accommodated within the groove. Further, no electronic component is disposed around the outer circumference of the stator assembly and therefore the radial dimension also can be kept small.

摘要： An optical entire-circumference encoder includes a plurality of rotation slits provided to transmit light at an equal pitch radially around a rotation axis as a center in a rotation track. A plurality of fixed slits is provided to transmit light at an equal pitch in a plurality of regions radially around the rotation axis as the center in a fixed track. A plurality of light receivers is disposed in a vicinity of the rotation axis to receive a light guided by the light guide in the regions respectively. The fixed slits in one of the regions and the fixed slits in another region adjacent to the one of the regions among the regions in the fixed track are formed so that a phase difference by which a rotation direction of the rotor is determined occurs between light reception signals of the plurality of light receivers.
