AI Technical Summary
Technical Problem
The closed magnetic field of the excitation brake interferes with the magnetic field of the magnet in the magneto-electric encoder, causing the magnetic field distribution to be distorted, affecting the signal recognition of the magnetic induction chip, and thus leading to unstable motor operation.
Method used
By setting the magnetic flux of the N and S poles of the magnet to be unequal, a uniformly rotating magnetic field is synthesized, ensuring that the magnetic induction chip obtains a stable magnetic signal and eliminating the influence of the excitation brake on the magneto-electric encoder.
Benefits of technology
Ensure the accuracy of the feedback signal from the motor drive module to avoid motor speed fluctuations and achieve stable motor operation.
