Abstract
The utility model belongs to the electrical field, in particular to a motor rear cover FET layout structure, which comprises a circuit board and a plurality of FET installed on the circuit board. The circuit board is fixed on the outside of the motor rear cover. The FET is disposed between the circuit board and the motor rear cover. The FET and the circuit board are in parallel. The face of the FET is toward to the circuit board, and the back of the FET clings to the motor rear cover. In the utility model, the installation space of the circuit board of the motor rear cover is reduced so that the use of motor is very convenient. The technical problem that the motor uses inconvenience because a large space is required in the installation of the circuit board on the motor rear cover is mainly resolved.
Description
Technical field
The utility model belongs to machine field, relates in particular to a kind of back end cover for motor field effect transistor arrangement.
Background technology
Owing to all can produce a large amount of heats during field effect transistor work, need radiating treatment, general all taking solved this problem at the back side of field effect transistor installation fin, but the volume of fin is bigger, and field effect transistor must be installed with the state perpendicular to wiring board, need provide bigger space so this class wiring board is installed, have limitation.Just there is this problem in the wiring board that motor rear end covers installation, by the arrangement of traditional field effect transistor, need install to wiring board a bigger space is provided, and this makes troubles for the use of motor.
Summary of the invention
The utility model provides a kind of installing space that dwindles the back end cover for motor wiring board, use the more convenient back end cover for motor field effect transistor arrangement of motor, mainly solving when wiring board that motor rear end covers is installed needs bigger space, uses the technical problem of inconvenience of motor.
Another purpose of the present utility model provides a kind of back end cover for motor field effect transistor arrangement that does not need fin, saves cost, has solved the technical problem that needs fin when field effect transistor is used.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises wiring board and installation some field effect transistor in the circuit board, described wiring board is fixed on outside the back end cover for motor, described field effect transistor is between described wiring board and back end cover for motor, described field effect transistor is parallel with described wiring board, and the front of field effect transistor is towards wiring board, and back end cover for motor is close at the back side of field effect transistor.
As preferably, described wiring board is rounded, and there is individual circular hole at the wiring board center, and described some field effect transistor distribute with one heart around described circular hole.
The beneficial effects of the utility model are: after the parallel installation with wiring board of field effect transistor, dwindled the installing space of wiring board, thereby made the use of motor more convenient; The rear end cap of motor is close at the back side of field effect transistor, with the rear end cap of the motor radiator as field effect transistor, has both omitted fin, saves cost, has improved radiating effect again.
Description of drawings
Fig. 1 is a kind of plan structure schematic diagram of the present utility model.
Fig. 2 is a kind of side-looking structural representation of the present utility model
1. wiring boards among the figure, 2. field effect transistor, 3. back end cover for motor, 4. circular hole, 5. screw.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: the back end cover for motor field effect transistor arrangement of present embodiment, comprise wiring board 1 and be installed in seven field effect transistor 2 on the wiring board 1, wiring board 1 is rounded, there is individual circular hole 4 at wiring board 1 center, wiring board 1 is fixed on outside the back end cover for motor 3 by three screws 5, field effect transistor 2 is between wiring board 1 and back end cover for motor 3, field effect transistor 2 is parallel with wiring board 1, and the front of field effect transistor 2 is towards wiring board 1, the back side of field effect transistor 2 is close to 3, seven field effect transistor of back end cover for motor 2 and is distributed with one heart around circular hole 4.
The utility model has effectively dwindled the installing space of the wiring board that field effect transistor is installed, volume shared after making wiring board be installed on the motor is less, thereby it is more convenient that motor is used, the radiator of while back end cover for motor double as field effect transistor, needed fin when having omitted the conventional mounting field effect transistor is saved cost.
