30 maximum (top) speed.
When controlling second switch K2 conductings and controlling the shut-off of first switch K1, the alternating current of the output of power supply circuits 10 can
Control silicon SCR copped waves after be supplied to alternating current generator so that motor rotate, wherein, the angle of flow of controllable silicon SCR is by adjustable resistance
The actual resistance of VR determines that the rotating speed of i.e. speech motor 30 is determined by the actual resistance of adjustable resistance VR.When regulation adjustable electric
When resistance VR increases its resistance, the controllable silicon SCR angle of flow is the angle between zero crossing is triggered when turning on to controllable silicon SCR
Degree is bigger, it is possible to provide fewer to the electric energy of motor 30, the rotating speed of motor 30 is less；It is hindered when adjustable resistance VR is adjusted
When value reduces, the controllable silicon SCR angle of flow is less, it is possible to provide more to the electric energy of motor 30, and the rotating speed of motor 30 is higher.
During regulation, the change in resistance of adjustable resistance VR is well-proportioned, so as to the change of motor speed can also be very equal
