摘要: An object of the present invention is to obtain a resin molded bushing which can easily perform positioning of an electric field relaxation shield in a switchgear. The resin molded bushing includes: an electric field relaxation shield which concentrically surrounds the outer periphery of an internal conductor made of conductor; a cast resin which covers the internal conductor and the electric field relaxation shield; and an elastic member which is disposed on the outer periphery of the electric field relaxation shield and is embedded in the cast resin. The height of the elastic member is equal to the thickness of the cast resin which covers the electric field relaxation shield.

摘要: A motor control device has a drive circuit that drives an electric motor with a battery as a power supply, a switch element that is provided between the battery and the drive circuit, the switch element supplying a current from the battery to the drive circuit when being put into an on state, the switch element cutting off the current from the battery to the drive circuit when being put into an off state, a voltage detector that detects a voltage at the drive circuit, and a controller that operates the drive circuit to control the electric motor. The controller turns on the switch element when the voltage at the drive circuit, which is detected by the voltage detector, is greater than or equal to a first predetermined value during stopping of the control of the electric motor.

摘要: A DC electric motor control device has a motor driving circuit that is constructed by a plurality of switching elements, a controller that operates the motor driving circuit to control a normal rotation or a reverse rotation of a DC electric motor, and an abnormality determination part that determines whether an abnormality is generated while the controller controls the DC electric motor. The controller previously performs reverse rotation control of the DC electric motor for a predetermined time using the motor driving circuit when performing normal rotation control of the DC electric motor, and the controller performs the normal rotation control only when the abnormality determination part determines that the abnormality is not generated during the reverse rotation control.
