It enables determining stepper motor completion one flap and makees required minimum movements time T1, and is corresponding pre- with job control instruction
If working time T2；
In the present embodiment, the job control of stepper motor is instructed, and can be determined according to stepper motor driven load,
Such as it is stepper motor driven be wind guide strip when, it is to be understood that job control instruction can be adjustment wind deflector

Under, stepper motor completes a shortest time for flapping work.After the driving time of stepper motor reaches minimum movements time T1, both
It can stop providing driving energy (in the period of T2-T1), and wait the initial time of next bat, then with the minimum movements time
T1 provides next bat driving energy, to drive stepper motor to complete next work of flapping.So set, making stepper motor both can be with
A movement clapped is completed according to the driving energy of minimum movements time T1, and can stop output after work is flapped in completion one and drive
