Rotary torque sensor HSTT

dynamicflange-to-flangevoltage output

Fast-rotating torque transducers are high-speed torque flanges designed for highly dynamic torque measurement and control tasks, particularly in e-mobility testing and drivetrain validation. They feature low rotor mass and high-speed capability to provide accurate transient torque signals with minimal inertia.


Main features

Speed resistance: typically rated up to 40,000 rpm for high-speed applications.

Rotor material: commonly manufactured with a titanium rotor to reduce mass and enable higher rotational speeds.

Low-mass design: rotor weights can be as low as ~400 g to minimize inertia and maximise dynamic response.

Function: torque flange / torque measuring flange for dynamic measurement and control applications.

Applications and advantages

Ideal for e-mobility testing where low rotor mass and high-speed capability are required.

Suited for test benches and measurement systems demanding fast transient torque capture and precise control feedback.

Reduced rotor inertia improves measurement bandwidth and responsiveness in dynamic test scenarios.
