A power conversion apparatus includes: a busbar; a magnetic core disposed to surround the busbar; and a fixing member that supports the magnetic core and is secured to the busbar. A noise filter includes: a magnetic core disposed to surround a busbar of a power conversion apparatus, and a fixing member that supports the magnetic core and is secured to the busbar.

Power conversion apparatus and noise filter

An electrical machine includes a first substrate, a second substrate, and a conduction support. The first substrate has a mounting surface. The second substrate is disposed in an overlay direction from the first substrate. The conduction support electrically grounds the second substrate and supports the second substrate while keeping approximately no contact with the mounting surface of the first substrate.

Electrical machine and power converter

A noise filter includes a magnetic core and a fixing member. The magnetic core includes a cylindrical integral body, and a wire is passed through the magnetic core. The fixing member is disposed inside the magnetic core and fixes the magnetic core to the wire.

Noise filter, circuit substrate, and power converter

An electrical-machine housing includes a main housing, a defining portion, and a holder. The defining portion includes a plurality of protrusions defining a plurality of regions in an opening of the main housing. The holder holds leading ends of the plurality of protrusions.

Electrical-machine housing and power converter

An LED indicatorconnected to industrial machinery including an inverter, includes: an LED substrateinto which a display control signal according to a state relating to the industrial machinery is input; and a plurality of displays, andconfigured to display in a lighting state corresponding to a state of the industrial machinery, on the basis of the display control signal input by the LED substrate. The plurality of displays, andeach include a partially circular-arc shape, and are generally arranged in an approximately annular shape. The plurality of displays, andinclude the two displaysthat generally configure a half ring at one side of the approximately annular shape, and the one displaythat generally configures a half ring at the other side of the approximately annular shape.

State display device of industrial machinery and power conversion device

A power converter includes a housing, a circuit element, and a cover. The housing includes a first space and a second space. In the first space, a circuit substrate is disposed. In the second space, a passage for a cooling fluid is disposed. The circuit element is disposed on the circuit substrate in the first space and protrudes into the second space. The cover covers at least a portion of the circuit element and includes a first portion and a second portion. The first portion protrudes from near the circuit substrate into the second space, and defines a first region that has a first area. The second portion protrudes from the first portion, and defines a second region that has a second area. The first area is larger than the second area as viewed from a direction in which the circuit element protrudes.
