  • Closed Loop Pressure Control System Development for an Automatic Transmission (.pdf)
    This paper presents the development of a transmission closed loop pressure control system. The objective of this system is to improve transmission pressure control accuracy by employing closed-loop technology. The control system design includes both feed forward and feedback control. The feed
  • Closed Loop Control in Hardness Testing
    Closed Loop Control in Hardness Testing. Closed Loop Control in Hardness Testing. Ed Tobolski. Instron Corporation. For more than 75 years, the most common hardness testing instruments used by industrial heating market have utilized dead weights to apply test forces. The reason for this is fairly
  • Stepper Motor Closes The Loop Around Tough Moves
    than +-1.8 , the motor switches to closed-loop mode. The position is corrected by exciting the motor windings to generate maximum torque based on the rotor position. For short and quick moves, the AlphaStep outperforms comparable stepper motors. Because it utilizes 100% of its torque, it moves
  • Closed-Loop Servo Puts Spring Force On Target
    the variability or tolerance of the absolute spring constant from one spring to another. For example, a spring with a nominal rate of 1,000 lb/in. could have as little as a 0.01-in. deflection variation from unit to unit. This.

  • May the force loop be with you
    control with a force feedback signal eliminates hysteresis. The graph shows the measured output force of a high-thrust linear motor in combination with a simple amplifier and strain gage in a closed-loop configuration. Industrial applications such as welding, grinding, and material testing require
  • Eliminating sensors from closed-loopcontrol
    , as well as full-load torque at zero speed. DTC, without an encoder, can provide 1 to 2% torque repeatability across the speed range. This is half that of other open-loop ac drives and on par with closed-loop ac and dc drives. Also, motor static and dynamic speed accuracy is far better than with PWM drives
  • Stepping Motors
    resolution of the PM stepping motors is less than that for hybrids. But unlike hybrids, some PM stepping motors perform well in closed-loop systems. Both cemf and iron losses are proportional to the number of poles in the motor. Thus, available torque from a PM stepping motor falls off more slowly
  • Sizing up BLDC motors
    . The required power can be determined by. where P = required power (W), T = torque (oz-in.), and N = speed (rpm). In this example, the motor must be rated for at least (28.4) (2,500)/1,340 = 53 W. One final consideration is inertia matching. Brushless dc motors in closed-loop speed-control
