  • Coreless DC Motors
    that they were produced economically enough to gain wide acceptance. Major advantages of coreless motors include very low inertia, low mechanical time constant, and high efficiency. Because the core is ironless, its low mass allows more rapid acceleration and deceleration than any other class of dc motor

    and torque. POUT = ω X T. A motion-control example includes a gantry-type drive mechanism. It uses a 38-mm-diameter coreless dc motor. The decision is made to double the slew speed with no change in the amplifier. The existing operating point is 33.9 mN-m (4.8 oz-in.) and 2,000 rpm (209.44 rad/sec

    and single observation mode. Total cost: nearly $88 million. A three-axis positioning system moves the appropriate optical system on the two reflectors on the large binocular telescope (LBT) into position. Coreless dc motor-encoder units from Faulhaber align the optical system in the new large binocular
  • Single sourcing motion control
    Following a few rules when selecting a single-source supplier makes putting together a motion-control system a snap. Coreless dc motors are used in a prosthetic hand. Gold-alloy brushes ensure fluidity of motion and low noise actuation. The rubber skin coating provides feedback to the motor
