Problems solved by technology

However, such a solution has low adhesion between the temperature sensor and the coil, there arises a problem of separating the temperature sensor from the coil, and thus there is a big problem of errors in the temperature measurement
In addition, there is another problem that the process is complicated and difficult due to the small installation space for the temperature sensor
However, there are problems in that the number of parts increases due to the installation of the cap member, the assembly process becomes complicated due to the increase of the installation process for the cap member, and it is difficult to secure an installation space for the cap member

Abstract

The present invention can provide a motor which comprises: a shaft; a rotor which is disposed on the outside of the shaft; a stator which is disposed on the outside of the rotor; a sensing magnet which is coupled to the rotor; a circuit board which is disposed above the sensing magnet, and comprises a sensor for sensing magnetic flux changes caused by the sensing magnet; and a cap member for covering the sensor, wherein said circuit board comprises a first board, a second board which is disposed separated from the first board, and a linking section which links the first board and the second board, said sensor is mounted on the second board, and said cap member is disposed passing through the separating space between the first board and the second board.

Description

Technical field [0001] The invention relates to motors. Background technique [0002] The motor includes a rotor and a stator. The coil is wound around the stator. The motor is required to be small in size but high in output power. However, when the output power of the motor increases, there is a problem that the internal temperature of the motor increases. Therefore, checking the internal temperature of the motor is a very important issue to ensure the performance of the motor. [0003] In order to measure the internal temperature of the motor, one solution is a temperature sensor mounted on the coil. However, such a solution has low adhesion between the temperature sensor and the coil, a problem of separation of the temperature sensor and the coil occurs, and therefore there is a big problem of errors in temperature measurement. In addition, there is another problem: since the installation space for the temperature sensor is small, the process is complicated and difficult. ...
