Abstract: A vacuum pump includes a fan including a rotational speed to be controlled to cool the vacuum pump, a temperature sensor, and a control device that regulates the rotational speed of the fan in dependence on a power consumption of a drive of the vacuum pump and on a temperature measured by the temperature sensor. Another vacuum pump includes an electrically driven fan, an air guide hood, and a conductor that leads from the fan to a supply connection for the fan. The conductor is connected to the supply connection via an electrical connector. The connector is separated from an air flow path, defined by the air guide hood, by a partition wall.

Abstract: The invention relates to a scroll pump comprising a pressure sensor integrated into the scroll pump.

Abstract: A vacuum pump includes at least two stages (2, 3), a motor (8) for driving pump-active elements of the two stages (2, 3), a transmission unit (7) for transmitting driving power from the motor (8) to the pump-active elements, a motor control (9) for controlling a rotational speed of the motor (8), and an evaluation unit (12) electrically connectable with pressure-sensitive signal sensor (10) located between the two stages for receiving a signal generated by the signal sensor and connected with the motor control (9) for transmitting an evaluated signal thereto, so that the motor control (9) can change a rotational speed of the motor (8) in accordance with the received evaluated signal.
