CS Model

This is a standard-size lineup of electromagnetically operated clutches that activate when an electric current is applied to the coil. Featuring a bearing-mounted design that allows for installation without worrying about alignment or centering, the series offers three types of armature assemblies with different mounting configurations, enabling you to select the one that best suits your installation requirements.

  • The dynamic friction torque Td is the value at a relative speed of 100 min⁻¹. Additionally, depending on the initial torque characteristics, a break-in period may be required.
  • The moment of inertia and mass of the rotating section are based on the maximum bore diameter.
