Mobile phone shake test
Mobile phone shake test
Customer requirements

Simulate the shaking frequency of a human hand to conduct a shaking test on the mobile phone camera. The operating angle is 1-6°, and the shaking frequency is 6Hz-10Hz. The smaller the angle, the higher the frequency. The motor is side-mounted, and the ma

Advantages of the Plan

This application requires a motor rotor with low inertia and fast response. Therefore, an inner rotor 263-123 motor is adopted, with a motor inertia of 0.0340 kg.m².

The application has requirements for the following error and speed fluctuation of the motor. Therefore, the cogging force of the motor is optimized, and the drive parameters are adjusted simultaneously to ensure that the position error in the uniform speed section is less than ±10 counts.
