Dismounting device

The invention relates to a dismounting device, which comprises a fixed seat and a press, the fixed seat is provided with a through hole for a rotor and a rotating shaft to pass through, and the hole wall of the through hole is provided with a boss for supporting the rotor; the fixed seat is mounted on a press, and a pressing head of the press can abut against one end of the rotating shaft, so that the rotating shaft and the rotor move relatively in the axis direction of the through hole; and when the rotor is supported on the boss, a gap is formed between the rotor magnet and the hole wall of the through hole. According to the dismounting device, the through hole is formed in the fixed seat, the boss is arranged on the hole wall of the through hole, the rotor and the rotating shaft penetrate through the through hole, a gap is formed between the hole wall and the rotor magnet, the damage of the rotor magnet caused by the fact that the hole wall abuts against the rotor magnet is prevented ...

Precise code zero offset and amplitude self-adaptation compensation method of optical-electricity encoder

The invention relates to the technical fields of decoding, compensation, debugging and the like of optical-electricity encoders, in particular to a precise code zero offset and amplitude self-adaptation compensation method of an optical-electricity encoder in order to resolve the problems that an existing method is high in complexity, the self adaptability of a decoding circuit is poor, a data packet obtained by an observation oscilloscope contains a large number of artificial errors, and the accuracy of an encoder is seriously reduced. The compensation steps include that photoelectric signals of the optical-electricity encoder are sampled through A/D, primary filtering is carried out on the sampled data through a recurrence average filtering method, and new data are obtained; a maximum value and a minimum value are obtained upwards and downwards from new data points in a sampling cycle through a bubbling method, smoothed estimation is carried on the maximum value and the minimum value ...
