Growing Demands for Torque Transducers in Auto Testing

Based on current demands for Interface measurement solutions, the auto industry is experiencing a high upsurge in using torque transducers. Specifically, EV manufacturers and parts makers are using torque measurement in testing the performance of electric motors and powertrains.

EVs have become a significant force and torque measurement sensor technology user, including our popular AxialTQ™ Rotary Torque Transducer product line. Many of our transducer models are also being used to test EV battery technology, including storage, capacity, and more.

Another growing use case requiring cutting-edge torque transducers is testing advanced driver assistance systems (ADAS) performance. ADAS systems rely on various sensors, including our torque transducers, to measure and control the vehicle’s dynamics. In these use cases, automotive engineers rely on supreme accuracy due to the critical nature of this safety feature. These types of use cases are pushing the requirement for accuracy further.

Finally, our torque transducers are being used in experiential automotive technologies such as fully autonomous and driver-assisted vehicle innovations. The accuracy of measurement is instrumental in bringing these inventions to market. Size, weight, and power (SWaP) is also a premium factor in these types of sensors. As more and more sensor technology is added to autonomous vehicles, the sensors must become more compact and efficient.

Specific products that Interface is supplying for these types of testing programs include high-accuracy reaction and rotary torque transducer technologies. This includes more miniature lightweight torque transducers to make integrating into test machines, production lines, and vehicles easier. Our expansion of Interface Mini Torque Transducers is helping with this requirement. We also provide more wireless torque transducer capabilities, eliminating the need for cables and wires and making testing more convenient and efficient.

Automotive Industry Applications Using Torque Transducers

Tire Force And Moment Using Contactless Force and Torque Transducer

A tire production company wants to put their tires under a stress test. They want to research the dynamic control capabilities of their tires. They want to measure both the torque and lateral force of the tire. Interface suggests using the AT105 Contactless Force and Torque Transducer to measure the tire lateral force and torque. Torque and force results can be displayed and graphed when connected to the SI-USB4 4-Channel USB Interface Module. After conducting a stress test on their tires, the tire production company could record and log the measurements of the torque and lateral forces implemented on their tires.

Vacuum Testing Using Rotary Torque Testing to Optimize Automotive Performance

The vacuum pump in a car plays an integral part in several systems, such as power brakes, HVAC, and sometimes even in the turbocharger or emissions control systems. Its primary function is to create a vacuum or negative pressure within a specific system. A torque test needs to be performed to ensure it is performing correctly. Interface’s T2 Ultra Precision Shaft Style Rotary Torque Transducer with torque couplings can be attached to the vacuum pump during performance testing. It will measure the amount of torque that is being used on the pump’s motor or drive system. When connected to the customer’s computer, results can be displayed, recorded, and logged using the SI-USB4 4-Channel USB Interface Module. Read Vacuum Testing for Automotive Performance

Torque Measurement For Electric Vehicles

Electric vehicle manufacturers need a torque measurement system for motor testing. These motors run at significantly higher rotational speeds than their internal combustion engine (ICE) counterparts and have much higher power densities due to their small size and lightweight. The system would be used to test the torque and speed of their electric motors to achieve and ensure optimum instant peak torque performance. Interface’s AxialTQ™ Wireless Rotary Torque Transducer is highly accurate with the highest quality torque measurement. This product comes with the AxialTQ™ Output Module and the provided AxialTQ™ Assistant software that can be installed on a test bench. Data results are calculated and collected in real time.

Motor Test Stand Using Torque Transducer

In the quality control lab at a major automotive manufacturing company, a test engineer needed to test, record, and audit the torque produced by a new motor design under start load. Interface supplied our AAxialTQ™ Wireless Rotary Torque Transducer connected between the motor and the differential on the drive shaft that could measure and record these torque values. Based on the data collected using the AxialTQ, AxialTQ Output Module, and customer laptop, the Test Engineer recommended optimizing the torque of the new motor design.
