Magnetic Coupling Torsional Stiffness Testing Machine
Category：Torsion Testing Machine
Introduction
The Magnetic Coupling Torsional Stiffness Testing Machine is designed to evaluate the torque transmission and torsional performance of magnetic couplings under static and dynamic operating conditions. The system consists of a loading system, transmission system, data acquisition and processing system, and control and display system.
It can measure torque, torsion angle, and rotational speed while displaying torque-time, torsion angle-time, and torque-angle curves in real time. The system can be configured for different torque capacities and test speeds, making it suitable for magnetic coupling development, performance verification, production inspection, and quality control.
Application
