  • DC Motors
    brake. Dc motor speed can be controlled smoothly down to zero, immediately followed by acceleration in the opposite direction -- without power circuit switching. And dc motors respond quickly to changes in control signals due to their high ratio of torque to inertia. Wound-field dc motors
  • Dc motor impersonators
    , during a 2 motor speed increase. The curve duplicates the armature current for a dc motor performing the same operation. The net effect provides dc motor control response for ac induction motors. Synchronous dc motors often top the field in high-performance motor controls. This group of motors includes
  • Brushless DC Motors
    finishes. Because they have no commutator, brushless motors are more efficient, need less maintenance, and can operate at higher speeds than conventional dc motors. High efficiency and small size are especially important for military, aircraft, and
  • Coreless DC Motors
    . Because the core is ironless, its low mass allows more rapid acceleration and deceleration than any other class of dc motor. Other benefits gained by eliminating the iron core include the absence of magnetic fields acting on the laminations. This interaction in conventional motors appears as torque
  • Servo Control of a DC Brush Motor
    high speed peripherals. Further, the on-chip peripherals allow an absolute minimum cost system to be constructed. Closed-loop servo motor control is usually handled by 16-bit, high-end microcontrollers and external logic. In an attempt to increase performance many applications are upgrading to DSPs
  • Integrated Drive Electronics for Brushless DC Motors
    Brushless DC motors (BLDCs) achieve commutation electronically by utilizing a permanent-magnet. rotor, wound stator, and rotor-position sensing scheme instead of a mechanical commutator or brushes. found in brush-type DC motor designs. With brush wear or arcing eliminated and as a result of other
  • Permanent Magnet (PM) DC Gearmotors and Motors
    Permanent magnet DC (PMDC) motors provide a comparatively simple and reliable DC drive solution in applications requiring high efficiency, high starting torque and a linear speed/torque curve.
  • Reasons for Turning to Slotless DC Motor Technology
    . mechanism that would wear and eventually result in motor failure, brushless motors could be relied upon. to deliver performance over time. As for other advantages, conventional wisdom held that brushless. motors provide high speed and fast acceleration, generate less audible noise and electromagnetic
