Theory of operation and Performance analysis
1. Power plant
The driving part selects a stepping motor as power, and the stepping motor is an open-loop control element stepping motor part for converting an electric pulse signal into angular displacement or linear displacement. In the non-overload condition, the rotation speed and the stop position of the motor only depend on the frequency and the pulse number of the pulse signal and are not influenced by the load change, and when the stepping driver receives a pulse signal, the stepping driver drives the stepping motor to rotate by a fixed angle in a set direction. The angular displacement can be controlled by controlling the number of pulses, so that the aim of accurate positioning is fulfilled; meanwhile, the rotating speed and the rotating acceleration of the motor can be controlled by controlling the pulse frequency, so that the aim of speed regulation is fulfilled.
2. Rotation and transmission
The six blades 7 are connected by adopting a rotating mechanism to realize linkage, and one connecting rod 5 is pulled to drive the rest other connecting rods 5, so that the rotating rod 3 is driven, the blades 7 are driven to rotate, and the effect of changing the cross section is realized.
