Abstract

The rotating armature/capstan assembly of a high torque - low inertia capstan motor is assembled using an aluminum filled adhesive. The use of this adhesive insures good high-temperature stability and a high-resonant frequency coupling between mating aluminum parts.

Capstan Motor

The rotating armature/capstan assembly of a high torque - low inertia capstan motor is assembled using an aluminum filled adhesive. The use of this adhesive insures good high-temperature stability and a high-resonant frequency coupling between mating aluminum parts.

The motor's aluminum-winding armature 10 is attached to aluminum hub 11 by an adhesive, which maintains high stiffness and shear strength characteristics at both ambient temperature and high temperature, so that the motor's rotating assembly resonant frequency does not lower with increasing temperature. An exemplary adhesive is Hysol* EA934 amine cured epoxy adhesive with aluminum filler.

The motor's ceramic shaft 12 is attached to hub 11 and to the aluminum hub 13 of tape drive capstan 14 by the use of a similar adhesive. *Trademark of Hysol Corporation.
