Abstract
The present invention relates to a sensing module, and a sensing module according to the present invention includes a hall sensor for sensing a rotation of a sensing magnet provided on a rotary shaft of a motor, a holder mounted on one side of the hall sensor, And a fixing means for fixing the printed circuit board and the holder detachably to the outside of the housing of the motor.
Description
The present invention relates to a sensing module.
A typical Switched Reluctance Motor has a magnetic structure in which both the stator and the rotor are salient, the concentrator coil is wound on the stator, and the rotor does not have any excitation device (such as a winding or a permanent magnet) It is a motor that is made of iron core and has excellent price competitiveness.
In particular, the variable speed type switched reluctance motor generates continuous torque with the help of the sensor which detects the position of the converter and the rotor using the power semiconductor, and it is easy to control according to the performance required in each application field.
Generally, a sensing module, such as a sensing magnet for indicating the position of the rotor and a Hall sensor for sensing the sensing module, is disposed inside the motor, If an error occurs in the sensing module due to the environment, the motor should be discarded or disassembled and repaired.
Particularly, there is a problem in that the disassembling operation of the bonded bearings is difficult, and the parts damaged during disassembly must be replaced, resulting in a time and economic loss.
One aspect of the present invention is to provide a sensing module capable of replacing the components of the sensing module without disassembly of the motor.
The sensing module according to an embodiment of the present invention includes a Hall sensor for sensing rotation of a sensing magnet provided on a rotary shaft of a motor, a holder mounted on one side of the Hall sensor, a printed circuit board mounted on the other side of the holder, And fixing means for fixing the printed circuit board and the holder detachably to the outside of the housing of the motor.
Further, in the sensing module according to an embodiment of the present invention, the fixing means may be a fixing screw.
Further, in the sensing module according to an embodiment of the present invention, the holder and the printed circuit board may be formed with screw holes to which the fixing screws are coupled, respectively.
Further, in the sensing module according to an embodiment of the present invention, one side of the holder is inserted into the insertion hole formed in the housing and is positioned inside the housing, and the other side is fixed to the outside of the housing by the fixing means .
In the sensing module according to an embodiment of the present invention, the Hall sensor may include a sensing unit spaced apart from a side surface of the sensing magnet and a lead wire connected to the printed circuit board.
Further, in the sensing module according to an embodiment of the present invention, the holder may be formed with a coupling hole to which the lead wire is coupled, and the lead wire may be connected to the printed circuit board through the coupling hole.
The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.
Prior to that, terms and words used in the present specification and claims should not be construed in a conventional and dictionary sense, and the inventor may properly define the concept of the term in order to best explain its invention It should be construed as meaning and concept consistent with the technical idea of the present invention.
The present invention can replace the components of the sensing module without disassembling the motor, thereby preventing breakage of the components caused during the replacement operation.
Further, the present invention has the effect of facilitating the replacement work, reducing the replacement time and the replacement cost.
