  • Flywheel energy storage advances using HTS bearings.
    Three embedded Hall-effect switches provided position feedback to the drive electronics, which, in the motor mode, was a commercially available, 120 - volt , brushless-DC servo amplifier configured in an “open loop”.
  • Phidgets: Easy Development of Physical Interfaces through Physical Widgets
    Instead, he built a ‘Power Dimmer’: by screwing two servo motors into two off-the-shelf rotary dimmer switches, he could rotate them under program control to vary the amount of power going to two attached 120 volt outlets (Figure 9a).
  • Naval applications of electrical remote-positional controllers
    (1.1) Step-by-Step Servo using "Braham" Dual Motor An alternative arrangement using what is known as a "Braham" dual motor is shown in Fig. 3, in which the system has been made fully synchronous by the use of a magslip .... The dual motor is a 20- volt 2-pole d.c. shunt motor with the usual commutator at one end and three tappings, spaced 120 electrical degrees apart, brought out to slip-rings, at the other end.
  • The Effect of Unconventional Piston Movement on SI Engine Combustion and Emissions
    The drive must have regeneration resistors to prevent drive bus over volts during servo motor retardation. .... The Baldor NextMove ESB is a separate control unit with a 32-bit 120 MHz signal processor…
  • Automated telescope enclosure for the CHARA array
    The servo motor mounts were isolated from the telescope supports by utilizing the enclosure column ground flanges as the bolt down locations. .... Electrical power, supplied to the amplifier drive is 120 volt 3 phase.
  • Interactive compute-control of a six-legged robot vehicle with optimization of stability, terrain adaptibility and energy
    Power to the motor is from a standard 120 volt ,60hr. .... an integral part ofthe jointto provide the nec- essary rate and position information for a servo system.
