Abstract
Description
Technical Field
[0001] The utility model relates to the field of motors, in particular to a motor whose direction of rotation can be changed by a connection method. Background Art
[0002] In existing usage scenarios, sometimes the motor needs to be able to rotate clockwise and counterclockwise at the same time. Existing motors mainly change the direction of the magnetic field by changing the direction of the stator current to control the direction of the motor. This control method has high requirements for the motor and circuit, and the cost is relatively high. Sometimes, based on different usage scenarios, the motor needs to be able to rotate clockwise or counterclockwise in different devices according to the needs of the device, and the internal temperature sensor can be used. If motors that can rotate clockwise or counterclockwise are produced separately, the stocking cost will be relatively high. If these two requirements can be adapted through wiring, the cost can be minimized and the scenario requirements can be met while only one ordinary motor is produced. Utility Model Content

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0020] Reference Figures 1 to 3 , an embodiment of the utility model of a motor that changes the direction of the motor by connecting is proposed:
[0021] A motor whose rotation direction can be changed by connection means comprises a bracket 1, a stator 2, a rotor 3, a cooling fan 5 and an output shaft 4.
[0022] The bracket 1 is provided with bracket through holes at the top and bottom, respectively, and a connecting bearing is provided in the bracket through hole. The rotor 3 is fixedly connected with the output shaft 4, and the rotor 3 is provided in the bracket 1. The output shaft 4 is rotatably connected with the bracket 1 through the connecting bearing provided in the bracket through hole. The cooling fan 5 is provided on the rear end of the output shaft 4, and the cooling fan 5 is driven to rotate by the output shaft 4, so that the heat of the motor is dissipated by the cooling fan 5. The front end of the output shaft 4 is provided with a plurality of evenly arranged vertical connecting grooves 41.
[0023] The stator 2 includes a stator body, a main winding 12, a stator coil 11 and a temperature sensor 10. The two ends of the main winding 12 are respectively connected to the first input-output terminal 6 and the second input-output terminal 7 through an LC oscillation circuit to form a main winding circuit. The two ends of the series circuit after the temperature sensor 10 and the two stator coils 11 are connected in series are respectively connected to the third input-output terminal 8 and the fourth input-output terminal 9. Thus, a sensor circuit is formed. There are two first input-output terminals 6 and two second input-output terminals 7, one for connecting to an external circuit and the other for connecting to the fourth input-output terminal 9.
[0024] When in use, if the motor needs to rotate clockwise, the first input-output terminal 6 is connected to the fourth input-output terminal 9, and then the second input-output terminal 7 and the third input-output terminal 8 are connected to the positive and negative poles of the external circuit. If the motor needs to rotate counterclockwise, the second input-output terminal 7 is connected to the fourth input-output terminal 9, and then the first input-output terminal 6 and the third input-output terminal 8 are connected to the positive and negative poles of the external circuit. Regardless of whether clockwise or counterclockwise rotation is required, the third input-output terminal where the temperature sensor 10 is located is connected to the external circuit, so that the design purpose can be met.
[0025] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
