A torque sensor is a precision measuring instrument used to measure various types of torque, rotational speed, and mechanical power. Its applications are highly diverse, as detailed below:

Industrial Manufacturing

Motor and Drive System Testing: During the R&D, production, and maintenance of motors, it is essential to accurately measure the torque and rotational speed output by the motor to evaluate its performance and efficiency. For example, in the development of electric vehicle (EV) motors, torque sensors can precisely measure the motor's torque output under different operating conditions, thereby optimizing motor design and control strategies to enhance the power performance and driving range of EVs.

Machining Processes: In machinery such as lathes, drilling machines, and milling machines, torque sensors can monitor the cutting torque of tools to optimize machining parameters, improving precision and surface quality. They also help detect tool wear or breakage in a timely manner, ensuring production safety.

Robotics: Robots require precise control of joint torque to achieve accurate motion and force transmission. Torque sensors installed at robotic joints can monitor real-time torque, enabling force feedback control to improve operational precision and safety. This allows robots to perform complex tasks such as assembly, welding, and material handling.

Automotive Industry

Vehicle Powertrain Testing: In the R&D, production, and debugging of automotive engines, torque sensors measure the torque and rotational speed output by the engine to assess its power performance and fuel efficiency. Additionally, in the testing of transmissions, drive shafts, and other components, torque sensors can evaluate their torque transmission capacity and efficiency.

Driving Performance Research: By installing torque sensors on wheels or drivetrains, real-time torque changes under different driving conditions can be monitored, providing data support for tuning vehicle driving performance—such as optimizing gear-shifting logic and improving acceleration and braking performance.

Electric Vehicles (EVs): In EVs, torque sensors monitor the torque output of electric motors to ensure precise power transmission and control. They are also used in battery management systems to intelligently distribute electrical energy based on torque demands, extending battery life and improving driving range.

Aerospace Industry

Aircraft Engine Testing: Aircraft engines are critical components where performance directly impacts flight safety. Torque sensors measure the torque output of engines under various operating conditions, helping engineers evaluate performance and reliability while optimizing design and maintenance strategies.

Spacecraft Attitude Control: In spacecraft attitude control systems, precise control of thruster thrust is required for attitude adjustment and orbital control. Torque sensors monitor the torque output of thrusters to ensure accurate control, enhancing flight stability and maneuvering precision.

Other Applications

Scientific Research & Experiments: In fields such as material mechanics and mechanical engineering, torque sensors are used to study material mechanical properties and torque transmission characteristics of mechanical structures. For example, in material fatigue testing, torque sensors measure torque variations under cyclic loads to analyze fatigue life and failure mechanisms.

Medical Devices: In medical equipment such as powered surgical instruments and rehabilitation devices, torque sensors enable precise control of operational force, improving surgical safety and rehabilitation outcomes. For instance, in electric screwdrivers, torque sensors ensure that screws are tightened to the correct torque, preventing issues caused by excessive or insufficient force.
