Problems solved by technology

[0004] However, the motor in the above technology is cumbersome to operate when the fan needs to be cleaned, and the storage box and the fixing seat provided also make the structure of the motor more complicated and the volume becomes larger, so that the motor is easy to interfere with the matching mechanism during installation. And the assembly fails, which affects the use effect of the motor

Embodiment approach

[0025] As an embodiment of the present invention, the length of the locking plate 4 is the same as the sum of the depths of the No. 1 locking groove 32 and the No. 2 locking groove 23, and the top end of the locking plate 4 is rotatably connected with a rotating plate. 41, the side wall of the fixed ring 2 on the side of the No. 2 locking groove 23 is provided with a storage groove 42 matched with the rotating plate 41; during work, by setting the length of the locking plate 4, the locking plate 4 The outer end is flush with the side wall of the fixed ring 2 in the working state, preventing the outer end of the locking plate 4 from being disturbed by external force or affecting the assembly of the motor due to excessive protruding from the outer end of the fixed ring 2, but with this Simultaneously, the locking plate 4 is inconveniently pulled out from the inside of the two locking grooves. At the same time, at the same time, the top of the locking plate 4 is rotated to be conn...

Abstract

The invention belongs to the technical field of motors, and particularly relates to a DC drive permanent magnet variable frequency motor. The motor comprises a motor body. The motor body comprises a frame and a base, one end of the motor body is connected with a rotating shaft, the frame is connected with a fixing ring, the outer end of the fixing ring is provided with an end cover, the end part of the end cover is symmetrically provided with locking blocks, the side surface of each locking block is provided with a first locking groove, and the end surface of the fixing ring is provided with an arc-shaped groove. An elastic block is arranged in the arc-shaped groove, a second locking groove is formed in the side wall of the arc-shaped groove, and a locking plate is slidably connected to the interior of the second locking groove. By arranging the fixing ring and the end cover which are matched with each other, the end cover can be conveniently and quickly opened, a fan and the end coverin the motor are cleaned, the structure of the motor is greatly simplified, the size of the motor is reduced, interference between the motor and the outside during installation is reduced, and the convenience and practicability of the motor during use are improved.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a DC-driven permanent-magnet variable-frequency motor. Background technique [0002] Variable frequency motor refers to the motor that runs continuously within the range of 10% to 100% rated speed with 100% rated load under standard environmental conditions, and the temperature rise will not exceed the motor’s calibrated allowable value. It has the advantages of easy speed regulation and energy saving. AC motor Simple structure, small volume, small inertia, low cost, easy maintenance, durable, can expand capacity, realize high speed and high voltage operation, etc. The heat dissipation of the motor fan is weakened to a certain extent, and it is not convenient to clean the motor fan. [0003] There are also some technical solutions for DC-driven permanent magnet variable-frequency motors in the prior art, such as a Chinese patent with a patent number of 2018104490686, which propos...
