*The dynamic friction torque, Td, is measured at a relative speed of 100 min-1. Depending on the initial torque characteristics, break-in to condition the engaging surfaces may also be required.
*Keep supply voltage fluctuation to within 10% of coil voltage. Do not allow the energization rate to exceed 80%.
*The rotating part moment of inertia and mass are measured for the maximum bore diameter.
