Description

Technical Field

[0001] The utility model relates to the technical field of motors, and in particular to a Hall component, an insulating frame, an insulating frame component, a stator and a motor. Background Art

[0002] The installation structure of the Hall sensor of the brushless DC motor in the prior art is generally to weld the Hall element to the Hall plate, and then install the Hall plate on the tooth slot of the stator core, or the stator coil, or the motor end cover.

[0003] However, the above installation structure still has the following disadvantages:

[0004] (1) The Hall plate is installed in the tooth slot of the stator core, which easily transfers heat to the Hall sensor and causes the Hall sensor to fail. This structure can only use pin-type Hall sensors. The Hall plate of the pin-type Hall sensor needs to be installed manually, the installation process is complicated, the installation efficiency is low, and it is easy to cause failures due to static electricity breakdown during installation.

[0005] (2) The Hall plate is installed on the stator coil, which is easy to cause damage to the stator coil. Not only does it have the same problem as mentioned above, but the Hall sensor must be inserted into the tooth slots of the stator core to sense the magnetic field, which leads to an increase in the volume of the Hall plate, which also increases the axial volume of the motor, affecting the commutation accuracy and increasing the production cost.

[0006] (3) The Hall plate is installed on the motor end cover, which requires a dedicated accommodation space and connection structure. This places high demands on the installation space of the motor. The large size of the Hall plate will also increase the axial volume of the motor, which ultimately makes it difficult to ensure the commutation accuracy of the motor. Utility Model Content
