Problems solved by technology
[0003] Aiming at the deficiencies of the prior art, the present invention provides a protective cover for a three-phase permanent magnet synchronous motor, which solves the problem that the heat dissipation structure of the current motor is realized by the heat dissipation ribs of the motor shell and the cooling fan inside the rear end protective cover. , and the speed of the cooling fan determines the heat dissipation, and the speed of the cooling fan is the same as the speed of the motor. Therefore, the heat dissipation is uncontrollable, and the heat dissipation of the motor cannot be accelerated. It is a technical problem that is too limited

Embodiment
[0020] Embodiment: first control the electric push rod 5 to pull the sliding body 7 to move on the slide rail 6, because the sliding body 7 is connected with the fastening frame 13, the fastening frame 13 moves for this reason, so that the cover body 2 is assembled on the three-phase permanent magnet synchronous The rear end of the motor 1, accordingly, when the three-phase permanent magnet synchronous motor 1 works, its rotor shaft rotates with the driving gear 9, and the driving gear 9 passes through the speed change of the speed change gear set 8 on the shaft frame 14 to transmit the high speed Give the driven gear 10, for this reason the driven gear 10 will rotate with the gear shaft 12, thereby making the fan 11 on the gear shaft 12 rotate faster, and allow the fan 11 to rotate more quickly.
[0021] As a preferred solution, furthermore, a fixing frame 15 is provided between the electric push rod 5 and the bottom plate 4; the fixing frame 15 fixes the electric push rod 5 ....

The invention discloses a protective cover for a three-phase permanent magnet synchronous motor, which comprises a three-phase permanent magnet synchronous motor and a cover body, wherein the bottom of the three-phase permanent magnet synchronous motor is provided with a bottom plate, the cover body is arranged on the bottom plate through a guide rail structure, and the cover body and the bottom plate are provided with a push heat dissipation structure therebetween; the push heat dissipation structure mainly comprises an electric push rod, a sliding rail, a sliding body, a variable-speed gearset, a driving gear, a driven gear, a fan, a gear shaft and a fastening frame. The invention relates to the technical field of image-text display devices. The innovation of the invention lies in providing a protective cover capable of speeding up the heat dissipation. The heat dissipation structure inside the protective cover accelerates the rotating speed of the fan through the transformation ofthe variable-speed gear set, thereby being capable of speeding up the heat dissipation.
Description
technical field [0001] The invention relates to the technical field of graphic display devices, in particular to a protective cover for a three-phase permanent magnet synchronous motor. Background technique [0002] At present, the heat dissipation structure of the motor realizes heat dissipation through the heat dissipation ribs of the motor shell and the heat dissipation fan inside the rear-end protective cover, and the speed of the heat dissipation fan determines the amount of heat dissipation, and the speed of the heat dissipation fan is the same as the speed of the motor. The amount is uncontrollable, and the heat dissipation of the motor cannot be accelerated, which is too limited. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a protective cover for a three-phase permanent magnet synchronous motor, which solves the problem that the current heat dissipation structure of the motor is realized by the heat ...
