What does motor slant stage noise reduction mean

Motor oblique level noise reduction means a technology to reduce motor noise. Motor noise mainly comes from the oscillation of the electromagnetic field of the motor, and this technology reduces the noise generated by electromagnetic oscillation by changing the design of the motor so that the magnetic lines of force of the motor propagate in the magnetic circuit in a diagonal direction. This technology is generally used in some of the higher noise requirements of the occasion, such as medical equipment, audio and other fields.
