The traditional mechanical transmission will cause some problems that cannot be eliminated, such as mechanical fatigue, friction loss, vibration and noise. Precise installation accuracy must be ensured to ensure the stability of mechanical movement. However, after long-term use, the equipment will be damaged due to mechanical vibration or wear. The speed change device of the vertical drive loading mechanism is a device that changes the transmission ratio or speed of the output shaft and the input shaft. It adopts traditional frequency conversion speed regulation. The equipment maintenance is cumbersome and the maintenance cost is high, which affects the normal use and working cycle of the equipment. In addition, the permanent magnet speed regulator of the traditional structure has low magnetic field utilization, large turning radius, large equipment weight, large proportion of extra power consumption, large axial distance, complex heat dissipation system, high equipment cost and low transmission efficiency.
