Generator rotor with radiating branch sheet blocking plates

Abstract

The invention provides a generator rotor with radiating branch sheet blocking plates, and relates to the technical field of synchronous motors. The generator rotor comprises rotor sheets (1), nylon frameworks (2), insulation paper (3), a rotor shaft (4), rotor enameled wire windings (5) and rotor blocking plates (6), wherein the plurality of rotor sheets (1) are overlapped on the rotor shaft (4); the nylon frameworks (2) are arranged at shaft necks of two ends of the rotor shaft (4); the insulation paper (3) is stuck to the inner walls of the nylon frameworks (2); the rotor enameled wire windings (5) are wound in the wire inserted grooves between the nylon frameworks (2) and a rotor iron core; and the rotor blocking plates (6) are connected to the outer sides of the rotor enameled wire windings (5) in an inserting way. Under the situation that the stator and the rotator are not changed, the rotor enameled wires can be better fixed, and radiating area of the rotor is enlarged, so that temperature rise of the rotor is reduced, and conversion efficiency and insulation reliability are improved.

Description

Technical field: [0001] The invention relates to the technical field of synchronous motors, in particular to a generator rotor with a cooling manifold plug plate. Background technique: [0002] The function of the pressure plate and the plug plate is mainly to fix the enameled wire. When the generator is working normally, the speed of the rotor is from 3000 to 3600 rpm, and the enameled wire of the rotor will heat up and elongate, causing the entire rotor wire package to expand. Under the action of electromagnetic force and centrifugal force, the rotor enameled wire will easily rub against the inner circle of the stator. The power generation function will be lost after the enameled wire is broken. [0003] One of the existing designs of generator 1-20kw is to fix the iron pressing plate with bolts, and there are 1, 2, and 3 pressing plates on one side. Since iron is a magnetic conductor, magnetic flux leakage will be formed. For a single platen, the enameled wires on both ...

Problems solved by technology

[0004] One of the existing designs is to use nylon plug boards. Nylon is a poor conductor of heat and is not conducive to heat dissipation. It is equivalent to wearing a piece of clothing for the wire bag.

The raw material of nylon is brittle at low temperature, and it becomes soft quickly after the temperature rises, so it is thrown out to the inner circle of the stator, causing the entire generator to fail
