  • Vacuum pump with heat generation element in relation to housing
    Patent number: 10760578
    Abstract: A vacuum pump comprises: a pump device configured to rotate a rotor about a rotation axis supported by a ball bearing, thereby discharging gas sucked through a pump suction port from a pump exhaust port; and a control device attached to a side surface along a direction of the rotation axis of the pump device, including an electronic circuit having a heat generation element and a housing configured to house the electronic circuit, and configured to control operation of the pump device. The heat generation element directly contacts an outer plate of the housing not contacting the pump device, and does not contact an outer plate of the housing contacting the pump device.
