摘要： An electronic device includes a motor, a sensing device and a controller. The motor provides a motive power to the load. The sensing device measures a plurality of motion parameters of the motor. The controller calculates a real system parameter between the motor and the load according to the motion command and the plurality of motion parameters. According to the motion command and the plurality of motion parameters, the controller acquires a real value of a rotation speed of the motor. Moreover, controller establishes a system model according to the motion command and the real system parameter so as to acquire an estimated value of the rotation speed of the motor. If the first mean square error is not smaller than the first target value, the controller performs a particle swarm optimization algorithm to change the estimated value of the rotation speed of the motor.

摘要： An instant correction method for an encoder includes the following steps. The motion of a device under test is sensed to obtain a first wave signal and a second wave signal. The first and second wave signals are sampled to generate N first digital signal values and N second digital signal values. N positioning positions are generated according to the N first and second digital signal values, and the N positioning positions are added to a calculation group. A regression analysis is performed for the calculation group to generate a regression curve. The (N+1)-th prediction position is predicted using the regression curve. The ideal position of the device under test is determined at a time point of the (N+1)-th prediction position according to an ideal position curve. An error value between the (N+1)-th prediction position and the ideal position is applied to correct the device under test.

The concave structure is concavely formed in a surface of the main body and includes inner teeth. The inner teeth are contacted with plural second rollers of the second roller assembly. The speed reducer of the present invention is an epicycloid-epicycloid speed reducer or a hypocycloid-hypocycloid speed reducer. Since the speed reducer is designed to have four operating situations, the speed reducer can have various reduction ratios.

摘要： 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.
