Embodiment Construction
[0040] In order to make those skilled in the art better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0041] For a system for estimating the mass of a motor vibrator provided in this embodiment, please refer to figure 2 The motor vibrator mass estimation system includes a test terminal 100 and a motor test device 200. When the test terminal 100 performs a test, it receives the voltage and current at both ends of the motor and the tooling acc...

The present invention provides a method for estimating the mass of a motor vibrator, a storage medium, a test terminal and a system. The present invention first obtains the estimated mass value generated by estimating the mass of the motor vibrator, and then according to the estimated mass value and the acceleration of the tooling and Calculate the vibrator acceleration value of the motor from the mass value of the tooling, and then calculate the quality verification value of the motor according to the acceleration value of the vibrator and the voltage and current at both ends of the motor, and then judge whether the estimated quality value is equal to the quality verification value, and if so, the estimated The mass value is the actual mass value of the motor vibrator, if not, correct the estimated mass value and continue to calculate and judge. It can be seen that the present invention can estimate the actual mass value of the motor vibrator only by obtaining the acceleration value of the tooling and the voltage and current at both ends of the motor, which has very high convenience and is suitable for most test scenarios.
Description
【Technical field】 [0001] The invention relates to the technical field of linear motors, and in particular, to a method for estimating the mass of a motor vibrator, a storage medium, a test terminal and a system. 【Background technique】 [0002] like figure 1 As shown, in the linear motor model in the prior art, u e is the driving voltage of the motor, R eb is the DC impedance of the motor, L eb is the voice coil inductance of the motor, i is the current in the motor voice coil, u is the back electromotive force caused by the motion of the motor vibrator, F is the electromagnetic force, φ(x) is the electromagnetic force coefficient of the motor, k d (x) is the spring stiffness coefficient, x is the displacement of the motor vibrator, c d (v) is the resistance coefficient of the damper, v is the speed of the motor vibrator, m d is the mass of the motor vibrator. Under the excitation of a small driving signal, the linear motor will work in the linear region. At this time, ...
