Abstract
Description
Technical Field
[0001] This utility model relates to the field of motors, and more particularly to a motor with a temperature controller. Background Technology
[0002] In traditional motor structures, temperature monitoring typically relies on external temperature sensors or indirect methods to obtain winding temperature information, which suffers from poor installation stability and delayed temperature feedback. Especially for designs with built-in temperature controllers, existing technologies often face issues such as insufficient detection accuracy due to loose contact between the sensor and the winding, and complex wiring affecting maintenance efficiency. Furthermore, the main control panel is often integrated inside the motor, leading to increased device size and limited heat dissipation. In external control solutions, the electrical connection between the temperature controller and the main controller often relies on complex wiring, making it susceptible to electromagnetic interference and resulting in low assembly efficiency. Utility Model Content

[0011] Compared with the prior art, the advantages of this utility model are:
[0012] (1) This application embeds the thermostat into the skeleton receiving groove and directly abuts against the winding. Combined with the filling of thermally conductive adhesive, it not only ensures heat transfer efficiency and improves temperature detection sensitivity, but also achieves mechanical limiting through the three-sided closed structure of the groove to prevent the thermostat from shifting due to vibration.

[0020] The present invention will be further described in detail below with reference to specific embodiments:
[0021] like Figure 1 and Figure 2 As shown, a motor with a temperature controller is disclosed. The motor includes a housing 1, and a stator 2 is fixed inside the housing 1. The stator 2 includes an iron core 21, a frame 22, and windings 23 mounted on the iron core 21. A receiving groove 221 is provided on the frame 22, and the temperature controller 3 is disposed in the receiving groove 221, with its detection end abutting against the windings 23, enabling it to monitor the temperature of the windings 23. An adapter plate 4 is provided at the top of the frame 22, and an interface mechanism is provided on the adapter plate 4. The interface mechanism includes a temperature control interface 41 and a power interface 42 that are configured to work with the temperature controller 3. The temperature controller 3 is electrically connected to the power interface 42 and the temperature control interface 41 via wires to obtain power and transmit the detection data to an external main control panel. The adapter plate 4 is electrically connected to the main control panel via wires. This configuration allows the temperature controller 3 to be electrically connected to the main control panel while detecting the temperature of the stator 2, even when the main control panel is not located inside the motor.
[0022] Specifically, such as Figure 3 As shown, the bottom end of the receiving groove 221 abuts against the thermostat 3. The receiving groove 221 is a rectangular groove with a rectangular cross-section parallel to its depth direction. It is closed at three points along its circumference, abutting against the thermostat 3, and open at the other point, with the open end corresponding to the winding 23. This allows the sensing end of the thermostat 3 to abut against the winding 23, thereby detecting the temperature of the winding 23. In this embodiment, the size of the receiving groove 221 is slightly larger than the mounting end of the thermostat 3. After the thermostat 3 is inserted into the receiving groove 221, a heat-conducting adhesive is applied to bond and fix the thermostat 3 to the receiving groove 221. In other embodiments of this application, the size of the receiving groove 221 is slightly smaller than the size corresponding to the mounting end of the thermostat 3, and it is fixed to the thermostat 3 using an interference fit.
[0023] like Figure 2As shown, the iron core 21 has stator slots 211, and stator teeth 212 are provided radially inwardly protruding from the inner wall of the stator slots 211. The frame 22 has a plug-in portion 224 extending along its own axial direction, which is shaped to conform to the stator slots 211, so that it can be plugged into the stator slots 211. The winding 23 is wound on the stator teeth 212.
[0024] The adapter plate 4 is connected to the frame 22 in the following way: the frame 22 is provided with a terminal block 222, and three terminal blocks 222 are evenly arranged around the axis of the frame 22. A terminal 223 is provided in any terminal block 222. The adapter plate 4 has a pre-drilled insertion hole 43 corresponding to the three terminals 223. The terminal 223 passes through the insertion hole 43 to realize the connection between the adapter plate 4 and the frame 22.
[0025] The housing 1 includes an upper housing 11 and a lower housing 12, which are detachably connected by fasteners. Three pressure arms 111 are formed on the upper housing 11, which are arranged corresponding to the frame 22. After the upper housing 11 and the lower housing 12 are connected, the pressure arms 111 can abut against the top of the frame 22, thereby restricting the movement of the frame 22 away from the iron core 21 along the axial direction.
[0026] The iron core 21 abuts against the iron core base 24 at the end away from the frame 22. The iron core base 24 is provided with a mounting groove 241 in the shape of the iron core 21. The bottom end of the iron core 21 is embedded in the mounting groove 241. The outer edge of the iron core base 24 is provided with a connection hole corresponding to the upper housing 11, and a fastener that can pass through the connection hole connects the iron core base 24 to the upper housing 11.
[0027] During assembly:
[0028] The iron core 21 is embedded in the mounting groove 241 on the iron core base 24. The insertion part 224 on the frame 22 is placed downwards and inserted into the stator slot 211 of the iron core 21. Then, the winding 23 is wound around the stator teeth 212 of the iron core 21. The temperature controller 3 is installed into the receiving groove 221 of the frame 22 and coated with adhesive with thermal conductivity to bond and fix the temperature controller 3 to the frame 22. The upper housing 11 is placed on the frame 22 and connected to the iron core base 24 with fasteners. Then, the lower housing 12 is fixed to the upper housing 11 with fasteners.
