Embodiment Construction

[0104] Below in conjunction with accompanying drawing, do further example description for the present invention:

[0105] The invention involves two parts, one is a precise driving method for a linear motor based on driving parameters, and the other is a testing method for driving parameters of motor products. A method for improving the vibration consistency of a linear motor, characterized in that the drive signal is constructed with its accurate resonance frequency F0 and drive parameters when the motor is working;

[0106] The driving signal refers to the electrical signal applied to the motor input to drive the motor to vibrate, such as figure 1 V(t) shown in. The drive signal that the present invention adopts comprises two types:

[0107] (1) Sinusoidal signal: shaped like a function sinusoidal alternating voltage. in:

[0108] V m is the signal voltage amplitude;

[0109] f 0 is the signal frequency;

[0110] is the initial phase angle, since the variable t i...

Abstract

The invention proposes a method for improving the vibration consistency of a linear motor. This method obtains the resonant frequency and driving parameters of each motor product through testing, and constructs the driving signal based on the measured resonant frequency and driving parameters, so as to obtain the best energy efficiency ratio and the smallest harmonic noise without changing the manufacturing accuracy of the product , improve the consistency of motor vibration.

Description

technical field [0001] The invention belongs to the technical field of linear motor vibration, and in particular relates to a method for improving the vibration consistency of a linear motor. Background technique [0002] "Vibration" is an important mode for modern equipment to realize human-computer interaction. Mobile phones are a typical example. The usual "vibration mode" and the vibration response when touching the screen and pressing buttons are all using "vibration sensation" to realize human-computer interaction. [0003] Motors based on electromagnetic principles are the main components used to generate vibration in various equipment. As the vibration source in the equipment, the design requirements for the motor mainly include: small size, strong vibration, high energy efficiency ratio, low noise, etc. Compared with various types of motors, linear motors have obvious advantages in the above aspects, so they have become the main development direction of vibration ...
