ABSTRACT:
A drive roller torque reference cartridge for calibrating a drive force tester. The reference cartridge uses a magnetic hysteresis brake assembly to controllably resist the rotation of the cartridge drive roller. The magnetic hysteresis brake assembly includes a cylindrical permanent magnet within the drive roller and a coaxial remanently magnetizable sleeve surrounding the drive roller. The drag created by the reference cartridge is substantially independent of the temperature and rotational speed of the drive roller.
