The stators are bearing-mounted types, which can be easily set in place on the shafts.Two types are available for different shaft RPMs: a dry metal type and a ball bearing type. Miki Pulley has experience making a wide array of products customized to customer requirements by assembling three types of armatures with pulleys and gears and then combining these with shafts.

*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. Also, be careful that energization does not exceed 50%.
*The rotating part moment of inertia and mass are measured for the maximum bore diameter.
