==DEVICE AND METHOD FOR ESTIMATING INTERNAL TEMPERATURE OF ELECTRIC MOTOR AND CONTROL DEVICE FOR ELECTRIC MOTOR - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18331599 titled 'DEVICE AND METHOD FOR ESTIMATING INTERNAL TEMPERATURE OF ELECTRIC MOTOR AND CONTROL DEVICE FOR ELECTRIC MOTOR

==Simplified Explanation==

The abstract describes a device that estimates the internal temperature of an electric motor by using a thermal circuit. The motor consists of a stator core, a coil, a rotor, and a case that houses them. The coil is cooled by a first cooling liquid inside the case. The device considers the temperature of the cooling liquid after it absorbs heat from the coil as the same temperature as the case, and uses this information to estimate the internal temperature of the motor.

* The device estimates the internal temperature of an electric motor.
* The motor consists of a stator core, a coil, a rotor, and a case.
* The coil is cooled by a first cooling liquid inside the case.
* The device uses a thermal circuit to estimate the internal temperature.
* The device considers the temperature of the cooling liquid after heat absorption as the same as the case temperature.

== Potential Applications ==
* Electric motor manufacturing industry
* Automotive industry
* Industrial machinery industry

== Problems Solved ==
* Difficulty in accurately estimating the internal temperature of electric motors
* Lack of a reliable method to monitor the temperature of electric motors during operation

== Benefits ==
* Improved efficiency and performance of electric motors
* Prevents overheating and potential damage to the motor
* Enables better maintenance and monitoring of motor temperature


==Original Abstract Submitted==

A device for estimating an internal temperature of an electric motor. The electric motor has a stator core extending cylindrically in a direction of an axis and around which a coil is wound, a rotor arranged rotatably around the axis, and a case that houses the stator core and the rotor, the coil being cooled by a first cooling liquid in the case. The device estimates the internal temperature by using a thermal circuit that regards a temperature of the first cooling liquid after heat reception from the coil as a first temperature equal to a temperature of the case.
