COMPRESSOR MODULE, COMPRESSED-AIR SUPPLY SYSTEM, AND METHOD FOR OPERATING A COMPRESSED-AIR SUPPLY SYSTEM HAVING THE COMPRESSOR MODULE

A compressor module has a compressor and a speed-controlled brushless electric motor for driving the compressor. A motor current is produced during operation of the electric motor. The electric motor is assigned a motor electronics system with an electronic commutator and a speed controller. The compressor module is connected to or has an electronic control unit. The control unit is configured to specify, depending on the mean motor current, one of at least two different target speeds for the electric motor, specifically at least a predefined first target speed and a predefined second target speed, which is lower than the predefined first target speed, and to change over from specifying the predefined first target speed to specifying the predefined second target speed when the mean motor current reaches or exceeds a specified motor current limit value. The compressor module can be for a compressed-air supply system of a vehicle.
