    摘要: A compensating circuit for compensating the terminal voltage on the armature in a sensorless type DC brushless motor apparatus is described. The driving circuit of the motor apparatus outputs a three-phase power, and each phase is connected with a compensating circuit. The compensating circuit has a reference voltage, a resistance device, a diode device, a differential amplifier and a processor. The two terminals of the resistance device are respectively connected to the reference voltage and the anode of the diode device. The cathode of the diode device is connected to an output of the three-phase power supply. The two input terminals of the differential amplifier are respectively connected to the two terminals of the resistance device. The processor accepts the signal output from the differential amplifier and then calculates and outputs a compensating voltage.

    摘要: A dynamic magnetic locator includes a linking mechanism linked with a first sensor to horizontal move or rotate the first sensor; a second sensor horizontally arranged beside the first sensor; a third sensor vertically arranged atop the second sensor; and a control module connected to the sensors and receiving magnetic signals of the underground metal pipe. The control module controls the linking mechanism to horizontal move or to rotate the first sensor to obtain a plurality of magnetic signals. The control module processes the magnetic signals to obtain a position and a depth of an underground metal pipe.

    摘要: A detachable transformer for contactless power system includes a first magnetic coupling element wound with coil and a second magnetic coupling element wound with coil. The first magnetic coupling element and the second magnetic coupling element are of symmetric shape and arranged in contactless manner to provide contactless power coupling. The first magnetic coupling element and the second magnetic coupling element are designed to have concave portion and convex portion on facing surface thereof. Therefore, the magnetic flux can be confined and the magnetic resistance is reduced to enhance conversion efficiency of the detachable transformer.

    摘要: A reluctance force brake device applies the coupling and combining concept of the reluctance braking unit to the original rotating source or say mechanical rotation axle for kinetic energy output. The reluctance braking unit, utilizing electrical energy from forward electrical energy source or brake reverse recover energy, generates the reverse reluctance force to reduce the speed of rotating source to operate brake action. The driving design can be extended to absorb the brake reverse recovery energy for recycling in motives related applications, which can help to upgrade or replace the bake system of traditional mechanical vehicles or electrical vehicles, and improve the applicability for drive-by-wire development trend.
