The ultra-high-efficiency 750-watt 2-pole energy-saving and environmentally friendly motor is characterized in that the inner and outer diameters and length dimensions of the stator and rotor cores, the shape and size of the stator and rotor slots, and the number of slots have been coordinated and designed as a whole, which greatly reduces the stator and rotor. and the loss of the iron core; then add punching holes on the stator and rotor punching sheets to form iron core holes, increase heat and temperature convection in the motor, reduce and slow down the temperature rise; use special cast aluminum for the rotor to effectively improve the conductivity and heat dissipation effect; the stator The winding is tapped at half of the coil, which greatly reduces the loss of harmonic components and further reduces iron loss and copper loss. The comprehensive effect of various schemes has greatly reduced the power loss, so that the input power of this product is only 0.881kW under the premise of a stable output power of 0.75kW, and the energy conversion efficiency has reached 85.2%, which exceeds the highest level of the country's YE4 energy efficiency standard , also exceeded the highest international level IE4 grade standard, reached the international advanced level.

A honeycomb filter includes a pillar-shaped honeycomb structure having porous partition walls placed, surrounding a plurality of cells which serve as fluid through channels extending from an inflow end face to an outflow end face; and porous plugging portions provided either at the ends on the inflow end face side of the cells or at the ends on the outflow end face side of the cells, wherein the plugging portions include plugging portions that have voids therein, and in the plugging portions having the voids, porosity including the voids as pores ranges from 68% to 83%.

The disclosed fixing apparatus includes: a magnetic field generation apparatus for generating a magnetic field; a fixing belt for emitting heat generated due to the magnetic field; and first and second thermally sensitive magnetic alloys arranged inside the fixing belt. A first Curie point of the first thermally sensitive magnetic alloy and a second Curie point of the second thermally sensitive magnetic alloy are different from each other.

The invention provides a plug-in base of a molded case circuit breaker. The molded case circuit breaker can be connected with and disconnected from an electric loop in a plugging manner through the plug-in base. In order to achieve the purpose, the plug-in base of the molded case circuit breaker is designed and comprises a plug, a fixing column, a cover, a base shell, an outer busbar, a fixing angle plate, a flexible connector, a pressing plate, a limiting rod and an elastic piece, wherein the flexible connector and the outer busbar are fixed to form a connector, and the connector penetrates through and is installed in an installation base shell and is buckled and fixed through a cover. The flexible connector is arranged in the connector, and the flexible connector can be aligned with a connecting hole in the cover while moving up and down in the base shell through a pressing plate guide groove and a limiting characteristic in the base shell, so that when the plug is connected with the flexible connector, the plug can be automatically adjusted to be aligned with the flexible connector, push and compress the elastic piece and generate clamping force, and the flexible connector and the plug are tightly attached and clamped. The plug-in base has the characteristics of reliable contact, large clamping force, large contact area, low energy consumption, low copper consumption and the like.
