Abstract: A vibration suppression method for a servo motor and a load multistage drive system is provided. For a number N of fixed vibration frequencies and one vibration frequency varying with a load position existing in a multistage drive mechanism, a number of N+1 vibration suppression filters are adopted, and each filter is configured to eliminate a corresponding vibration frequency. Fixed vibration frequencies and a vibration frequency varying with a load position in a multistage drive system are measured by using an offline method, and the varied vibration frequencies are made into a two-dimensional table related to the load positions. The fixed vibration frequencies are eliminated by using fixed-frequency parameter vibration suppression filters; and the varied vibration frequencies are eliminated by using a variable-frequency parameter vibration suppression filter, and the vibration frequencies are obtained in real time according to the load positions and the two-dimensional table.

Abstract: A rotor structure of a magnet motor includes a rotating shaft and an iron core on the rotating shaft. Magnet grooves are disposed inside the iron core along a circumferential direction with a magnet provided therein. A distance between an edge line of the magnet groove close to a circumferential edge of the iron core and the circumferential edge of the iron core varies so that a width of a flux barrier formed varies. One end of a long side of the magnet groove close to the circumferential edge is formed with an anti-demagnetization groove communicating with the magnet groove, and an edge line of the anti-demagnetization groove tilts toward the circumferential edge of the iron core. Process slots are provided between the magnet grooves and the circumferential edge of the iron core that are used to increase a salient rate and reluctance torque of the motor.

Abstract: A method of measuring mechanical resonance frequency using a servo driver including the steps of: having the servo driver work under a torque control mode, by applying in the servo driver a preset torque drive signal, the motor drives the mechanical components in a microvibration state; collecting actual speed signals of the motor to obtain the actual speed signal sequence of the motor; the actual speed signal sequence of the motor being passed in sequence through a certain number of band-pass filters having a fixed pass-band frequency and different center frequencies to obtain filtered speed signals; the filtered speed signal sequences output from each of the band-pass filters being changed into absolute values and then accumulated to obtain accumulation values; comparing the accumulation values obtained from the signal sequences output from the certain number of band-pass filters, and the center frequency of the band-pass filter corresponding to the largest accumulation value being the mechanical resonance
