Abstract
An aircraft includes a compression system for pressurizing a cabin of the aircraft. The air compression system includes a first motor, a second motor and an inverter. The first motor compresses air at a compressor to pressurize the cabin, thereby generating heat. The second motor circulates a cooling air to cool the compressor. The inverter provides power to both the first motor and the second motor.
