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.
Standard Pulleys and Pulleys to client specification Depending on the vehicle model, mounting brackets to mount the generator on the engine could be available or can be specially designed
Safety alarmsShort circuit, overload, over temperature, low/high rpm, low/high voltage
Determine the pulley diameter designThe 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 = crankshaft 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.
Attention! The 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.
