  • Torque motor information

    This is a request for help from anyone who may have information about
    some specific equipment.

    1. As part of a study into the passive mechanical properties of the ankle
    joint, we need a torque motor with an operating range up to 50-70Nm. We
    intend to control the motor using a variety of input signals at various
    frequencies. Does anyone have any information about suitable motors?
    We would appreciate details of:
    torque application capabilities
    suppliers and models
    costs if known
    inputs used for control
    validation studies which might exist
    gearing systems used
    noise/signal characteristics
    any other useful information.

    2. Some colleagues are involved in a psychophysical study into apprehension
    in elderly "fallers". They are looking for ambulatory physiological
    monitoring equipment to measure heart rate, respiratory rate, galvanic
    skin response and skin temperature. Does anyone know of commercially
    available equipment to do this?

    Thank you, in anticipation.
