  • VACUUM PUMP, SCROLL PUMP, AND MANUFACTURING METHOD FOR SUCH
    Publication number: 20230383750
    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.
