Lamborghini Motor 3980N530

This electric motor is intended for Lamborghini burners and boilers with modulating premix design. It drives the combustion air fan, supplying air for combustion and, in room-sealed appliances, extracting flue gases. It is suitable for control via mains supply, PWM, or a 0-10V signal. The motor carries type designations 111857, 113685, and F39819430.

Such fan motors are selected by matching the required air flow and pressure, outlet direction and orientation, impeller diameter, supply voltage, and control mode (mains, PWM, or 0-10V). The mounting flange pattern must also match the fan housing. Before fitting, confirm the replacement matches the original in shaft dimensions, voltage, and control signal type. If the original used a specific speed feedback signal, the replacement must be compatible for correct modulation.

Common failure modes include worn bearings, impeller imbalance from deposits, a failed start capacitor, and speed feedback errors that the burner control reports as an airflow fault. Incorrect speed feedback or voltage can cause the burner to lock out or operate at the wrong output. When these symptoms occur, check the motor bearings, impeller condition, capacitor, and speed feedback wiring.
