2.5.21  Diagram electronic governor (standard) 

 
In  addition  to  the  mechanical  governor,  the  W-SQ-Pro 
15/10.8  is standard equipped with an electronic governor. 
A governor keeps the speed (RPM=Rotations Per Minute) 
of  the  engine  at  a  fixed  value.  The  RPM  of  the  engine 
correlates with the frequency of the electrical output (1500 
RPM =50 Hz) of the alternator. 
Under  full  load  the  RPM  of  the  Whisper  models  that  has 
only a mechanical governor can drop 75 RPM (=2.5 Hz) at 
full load and will go further down or collapse when further 
loaded. However the engines with the electronic governor 
will keep the RPM and frequency at the set value. As the 
voltage is related to the frequency, the voltage will be more 
stable as well.  
The  RPM  represents  power  and  the  alternator  performs 
better as well on a higher speed. Whisper models with an 
electronic governor will bring more power. 
So the electronic governor offers three advantages: a more 
stable frequency and voltage and more power.  

The electronic governor system contains two parts:  
1 

The actuator controls the engine speed. This actuator 
replaces the standard hold solenoid that is on all other 
mechanical controlled Whisper engines. The actuator 
controls the RPM directly on the fuel rack inside the fuel 
pump  without  levers  and  other  mechanical 
transmissions.  

2 

A microprocessor keeps the speed at the set value by 
controlling  the  actuator.  The  microprocessor  is 
programmed at the Whisper Power factory and many 
parameters  are  set  to  perform  well.  It  should  not  be 
necessary  to  make  adjustments.  When  adjustments 
are necessary this can only be done with the help of an 
interface  to  a  computer  and  special  software  to  get 
access to the microprocessor.  

 
The  Whisper  Power  electronic  governor  does  not  need  a 
pickup  device  in  the  flywheel  housing  that  counts  the 
passing tooth of the flywheel and determines the exact RPM 
of the engine, because the processor uses the 50 Hz of the 
AC output voltage as a reference.
