How it works
The WhisperPower W-BD alternator is designed for installation in the
vehicle’s or boat’s engine compartment and has to be driven by a belt
of one of the engine’s pulley. In most cases an additional pulley has to
be installed. The alternator’s output is connected to an inverter/power
supply, which converts the variable incoming current into a stable sine
wave 230 VAC 50 Hz.

The graphs show the available AC power corresponding to the generator
speed. The speed of 2 pulleys relate to each other proportional to the
diameter of the pulleys. First one need to know the engine speed =
116*79*19 mmcrankshaft speed when idling and at full speed. When the drive pulley
is not on the crankshaft the rpm of the pulley drive shaft must be
determined. The pulleys should be selected in such a way that at low
speed the generator can bring the power required. However the max.
speed must not exceed 15000 RPM.

T he W-BD5 model needs 6500 RPM to
generate 5 kW. Compared with
the W-BD 3.5 the 5 kW
model will also need more
RPM (3200) to generate
1 kW. Refer to the graph.
