Abstract: A linear motor includes a case, a magnet assembly and a coil assembly. The case is disposed along a first direction. The magnet assembly includes at least two first magnets, among which the first magnets are disposed corresponding to and between two first magnetic yokes, respectively. The coil assembly includes a winding coil having an exposed portion, among which the exposed portion is extended along a second direction and disposed between the two first magnetic yokes, and the exposed portion is at least partially overlapped with the two first magnets in a third direction. As a result, the coil assembly and the case are driven to reciprocate along the first direction by the winding coil due to the magnetic force, thereby solving the magnetic disturbing issue, enhancing the driving force of the linear motor, and optimizing the mechanical rigidity.

Abstract: A rotary machine device configured to contact with an external object is provided. The rotary machine device includes a rotary motor, a first encoder, a fixed housing, a fixed shaft, an output shaft and a second encoder. The rotary motor includes a motor housing and an exerting shaft. As the rotor of the motor housing rotates for a rotation angle, the rotor drives the exerting shaft to rotate for an exerting angle. The first encoder detects the rotation angle of the rotor. The output shaft includes an elastomer and is inserted in an accommodation hole of the fixed shaft. The elastomer is penetrated through the output shaft and is connected to the exerting shaft. The second encoder includes a disk and a sensor disposed on the exerting shaft and the fixed shaft respectively. The sensor detects the exerting angle of the exerting shaft through the disk.

Abstract: A speed reducing device includes a motor and a speed reducing mechanism. The speed reducing mechanism includes at least one roller assembly, a cycloid disc, at least one fixing disc and a positioning assembly. The roller assembly is disposed within a rotor portion of the motor. While the roller assembly is rotated with the rotor portion, the roller assembly is eccentrically revolved. The roller assembly includes a wheel disc and at least one roller. The cycloid disc includes a main body and at least one cycloid tooth structure. The cycloid tooth structure is protruded from an outer periphery of the main body and in contact with the corresponding roller. While the roller assembly is eccentrically revolved, the at least one cycloid tooth structure is pushed against the corresponding roller, so that the cycloid disc is correspondingly rotated.
