Contactless temperature sensor

Desired outcome

Our company develops and manufactures electric motors with high power density.
Temperature is measured in stator of electric motor, directly on the copper windings, however, we don't have any temperature sensing on the rotor. This would be extremely welcome in many applications where our motors are installed.
Some of our clients use IR sensors, but this option is expensive and not highly reliable.

Also induction sensors exist, but we would rather go in a direction where classic temperature probe is attached to the rotor, and it emits its signal about resistance or temperature data to its monitor or controller.

We are open to solutions and ideas, also ideas outside the described ones above.

Initial Problem Description

Because temperature in our electric motors is measured only in stator part, we can only assume what is the temperature in the rotor part.
But the problem is because our motors operate in totally different environments. Problems with rotor overheating can appear in case the motor is operating in environment where ambient temperatures are high and motor bay doesn't provide sufficient fresh air ventilation.

Context

Because temperature in our electric motors is measured only in stator part, we can only assume what is the temperature in the rotor part.
But the problem is because our motors operate in totally different environments. Problems with rotor overheating can appear in case the motor is operating in environment where ambient temperatures are high and motor bay doesn't provide sufficient fresh air ventilation.
This is the case in many marine applications where motor is installed in compartment which is completely sealed because of potential water ingress.
Another client we have produces mining vehicles and motors operate in mines where humidity and ambient temperature is very high (50-50°C) due to different machines heating up small volume of air.
Also, dusty and dirty environment can make end users to close and seal motor to protect it from harm effects from environment.

Connection to cross-cutting areas

We design and manufacture high-efficiency electric motors and generators that aim to support a greener environment over time. By optimizing energy use, our products help reduce carbon emissions and promote sustainability. Our motors power a wide range of applications, including snowmobiles, cars, drones, and airplanes, providing reliable, efficient solutions across industries.

Input

We don't have specific trends or instructions at this stage, so we would require initial concept and idea development. One possible concept could be a contact solution using a classic temperature probe, such as a PT1000, that enables contactless, wireless communication of temperature data to its monitoring system. This would allow for easy integration and monitoring without the need for direct physical connections, offering flexibility and efficiency in temperature sensing applications. We're open to exploring this concept further and refining it based on feasibility and performance.

Expectations

We are developing a concept for contactless temperature measurement and wireless communication between a temperature sensor probe and its monitor or controller. This innovation aims to enable efficient, real-time data transmission without physical connections, offering improved flexibility and reliability. The solution would simplify integration, enhance performance, and provide advanced temperature monitoring capabilities across various applications while reducing maintenance and wear on traditional wired systems.

Desired Team Profile

We don't have any special requirements or conditions, although we think the most appropriate would be candidates with mechanical engineering or electrical engineering background.
It is required that candidates will be open to new ideas and they have ambition for new knowledge and development.
As the best solution will not be developed immediately, persistence is also required.

Additional Information

Due to our ongoing expansion in the global market and our vision to become a leading manufacturer of axial flux, high power density motors, we are seeking innovative solutions that will enhance the reliability and efficiency of our products. These solutions are crucial for maintaining high performance and meeting the growing demands of our customers worldwide. By adopting cutting-edge technologies and advancing our motor designs, we aim to set new industry standards and further strengthen our position as a top-tier manufacturer in the competitive electric motor market.
