  • Patent number: 11628729
    Abstract: An inverter controller includes a processing circuitry. The processing circuitry is configured to obtain a command rotation speed transmitted repeatedly from outside of the inverter controller, count a command obtaining interval that is a period from a point in time where an old command rotation speed was obtained to a point in time where a new command rotation speed is obtained, set a target acceleration of the electric motor when the command rotation speed has been obtained, and control the inverter circuit such that the electric motor rotates at the set target acceleration. The processing circuitry is configured to calculate a command acceleration based on the counted command obtaining interval and the new command rotation speed, the command acceleration being set as the target acceleration.

  • Publication number: 20230105734
    Abstract: An electronic component testing apparatus that tests a DUT (device under test) disposed in a carrier includes: a test head including a socket; and an electronic component handling apparatus that presses the DUT in the carrier against the socket. The socket includes: contactors disposed to correspond to terminals of the DUT that are exposed to the socket via a first opening of the carrier; and a first wall projecting toward the carrier along a pressing direction of the DUT. The electronic component handling apparatus aligns the terminals with the contactors by pressing the DUT against the socket such that a first pressing mechanism of the carrier presses the DUT against the first wall.
