  • Motor drive device
    Patent number: 10813255
    Abstract: A motor drive device provided to a control panel to drive a plurality of motors includes a plate-shaped fin base that includes a first plate surface and a second plate surface, and a plate-shaped heat radiator that is thermally connected to the first plate surface and is provided with a first normal to its plate surface intersecting a second normal to the first plate surface. The motor drive device also includes a semiconductor device that drives a first motor and is thermally connected to the heat radiator, a semiconductor device that drives a second motor and is thermally connected to the first plate surface, and fins that are thermally connected to the second plate surface opposite from the first plate surface of the fin base and are provided in an air passage formed in the control panel.
