A kind of temperature sensor for stator of new energy motor and its assembly method

Abstract

The invention discloses a temperature sensor for a stator of a new energy motor and an assembling method thereof, comprising a silicone rubber sleeve, a temperature sensor body, a temperature sensor lead and an enameled wire; the temperature sensor body is located at an opening at one end of the silicone rubber sleeve, The temperature sensor lead is located in the silicone rubber sleeve, one end of the temperature sensor lead is electrically connected to the temperature sensor body, and the other end penetrates to the outside of the silicone rubber sleeve; the enameled wire includes a long part, a short part and a curved part. The long part is inserted into the silicone rubber sleeve, the short part is attached to the outer wall of the silicone rubber sleeve, and the curved part is distributed and fixedly connected to the short part and the long part One end face away from the temperature sensor body; the short part and the long part are arranged in parallel. The invention can prolong the service life of the stator.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a temperature sensor for a stator of a new energy motor and an assembling method thereof. Background technique [0002] At present, the stator temperature sensor of the new energy motor is bound on the stator wire package, and the lead wire is a flexible wire with a diameter of about 1mm. It will also result in the need to untie the sensor leads first and then wrap them on the three-phase leads again after the process is completed. Frequent operation will inevitably lead to damage to the leads and cause the stator to be scrapped. [0003] For example, the patent with the application number CN201880065184.6 discloses a stator of a rotating electrical machine and a rotating electrical machine. A temperature sensor and a temperature sensor bracket are arranged on the stator of the rotating electrical machine, and an elastically deformable card in the height direction on t...

AI Technical Summary

Problems solved by technology

[0002] At present, the stator temperature sensor of the new energy motor is bound on the stator wire package, and the lead wire is a soft wire with a diameter of about 1 mm, which cannot be formed and will be placed on the stator, which may easily cause damage to the lead wire during the process; generally, three-phase lead wires wound on the stator are used. On the other hand, it will also cause the sensor lead wire to be untied first during the process operation and then wound on the three-phase lead wire again after the process is completed. Frequent operation will inevitably damage the lead wire and cause the stator to be scrapped.

[0003] For example, the patent application number CN201880065184.6 discloses a stator of a rotating electrical machine and a rotating electrical machine. A temperature sensor and a temperature sensor bracket are arranged on the stator of the rotating electrical machine. The joint part and the clamping part fix the temperature sensor on the stator winding, but the signal line of the temperature sensor is still placed naturally, and there is a problem of lapping on the stator, which is easy to cause damage to the signal line during use
