Short development times for new electric motors are crucial. Since time is limited, it is essential to avoid mistakes that would prolong the development phase. We offer a solution that helps our customers to:
- Clearly differentiate between torsional oscillations and vibrations.
- Fully rely on your measurement results.
- Reliably achieve repeatable and reproducible measurement results.
- Constantly improve your simulation results.
- Actually optimize the inverter’s strategy.
Torque Ripple
Reliable torque ripple determination of up to 25 kHz.
Cogging Torque
Accurate measurement of cogging torque according to ISO21782-3 without replacing or recalibrating the measurement equipment.
Simulation
Improved simulation results due to measurement results in Newton and Newtonmeter.
Lateral Forces
The measurement of lateral forces allow a clear differentiation between torsional oscillations and vibrations.
The measurement technique is based on the piezoelectric effect, which gives you several advantages such as maximum stiffness, high bandwidth measurement and the fact, that only one transducer covers the entire measurement range without recalibration. The measurement chain consists of the Dynamic Torque Transducer, AVL X-ion™ and AVL IndiCom™ Dynamic Torque Toolbox – this combination utilizes the full potential for your e-motor testing.

Plug & Play
Plug & Play allows an easy integration and re-installation on another AVL e-motor testbed.
One-stop Shop
The entire measurement chain out of one hand ensures compatibility over the complete product lifecycle.
State-of-the-art Measurement Technology
The unique measurement technology empowers the development to be one step ahead of competition.
Ease of Use
The intuitive user interface of IndiCom (Dynamic Torque Toolbox) allows a straightforward interpretation of the
measurement results.
Clear Differentiation Between Torsional Oscillations and Vibrations
By clearly differentiating these two phenomena the efficiency during the development phase is increased.
Rely on Your Measurement Results
Since the Dynamic Torque Transducer is always installed at the same position on the testbed, you can trust the collected measurement data.
Repeatable and Reproducible
The combination of the fixed installation position and the outstanding accuracy ensure not only repeatable, but also reproducible measurement results during the development phase.
Measurement Results in Newton and Newton-Meter
Receiving the measurement results in N and Nm improves the simulation as the intermediate calculation from acceleration data (mm/s²) is not required anymore.
With the Dynamic Torque Transducer you can see all forces and moments of dynamic processes of an electric motor – for optimization, durability, and production assurance.”
