The use of belt structure in the application of stepper motors is relatively common. There are many kinds of motors on the market. Why do everyone choose stepper motors for structural control? Let's analyze them below.
In fact, the belt mechanism is a low-rigidity mechanism, and gain adjustment is required when using other motors. For example, AC servo motors, AC servo motors have torque control, so you need to make corresponding adjustments according to the load status. Relatively speaking, it is more susceptible to vibration, and when the gain is low, the response is poor. The stepping motor has better synchronization and has no requirement on the rigidity of the mechanism, and can get the movement as set without gain adjustment.
