  • Servo On A Chip
    field. The term applied to this transformation is field-oriented control (FOC). This process results in two equivalent dc-motor current quantities: a torque-producing component and a field-control component. The ac-motor control system calculates the two quadrature voltages that force the current

With brush wear or arcing eliminated and as a result of other. factors influencing brushless motor performance, BLDCs can achieve rapid acceleration and high speed,. generate less audible

  • Replacing Your DC Motors? Think AC
    . In addition, over the past 10 years, AC drives have improved to the point where their speed control is far more precise, rivaling that of servo drives. What's more, the AC motor and drive together often cost about the same price as the DC motor alone. The development of modern AC motors and drives
  • Motor Eliminates Cogging Torque for Ultra Smooth Servo Track Writer
    Air bearing spindles for such demanding and close-tolerance applications as wafer Manufacturing and handling equipment and servo writers require especially smooth velocity. Typically, we use an 8-pole slotted brushless DC (BLDC) motor in these applications. However, for a recent servo writer

  • Stepping Motors
    with speed than in hybrids and more rapidly than in dc motors. The result is that PM stepping motors operate effectively at higher speeds -- up to about 3,500 rpm -- than hybrids but not as high as dc types. The speed range for PM stepping motors, however, suits a wide range of servo applications
