  • High Speed Mixing: Saw-tooth Dispersers vs. Rotor/Stator Mixers (.pdf)
    The saw-tooth disperser and rotor/stator mixer are two of the most widely used high speed mixers yet many are unaware of the differences in their utility and operating capacities. Knowing the unique attributes of these devices is important in mixer selection and process optimization.
  • Scale Up of High Shear Rotor-Stator Mixers
    represents the first step in exploring the particular benefits of rotor/stator technology for a given application. This familiar laboratory tool is generally equipped with a variety of interchangeable attachments that allow it to operate in a variety of mixing modes - as a conventional HSM, as a propeller
  • Feedback on speed
    A novel process offers an inexpensive way to monitor the speed of small permanentmagnet motors. For many years control makers monitored servomotor velocity and rotor position through use of various built-in or attached devices. The last few decades have seen a mushrooming of applications for motors
  • Explorer Speed Calculation
    The objective of this paper is to describe conceptually how the Explorer calculates the operating speed of an induction motor. This calculation is disclosed in [3], and is significantly more involved than the methods presented in this paper. The concept, however, is accurately described here. Every
  • Load Torque Considerations: Fixed vs. Adjustable Speed
    Properly applying an AC VHS controller to an existing constant speed motor application requires a definition of the starting torque, the full load torque and the peak torque requirements of the load. The torque that is available for starting and peak load will be different on adjustable frequency
  • Avoiding Stick-Slip Chatter in Low-Speed Bearings
    static friction. At this point, friction drops to its kinetic value as rotation initiates and the rotor "jumps ahead " as it dissipates its stored elastic energy. Repetition of this sequence during slow-speed rotation often produces a stop-start jerking pattern, as illustrated in the accompanying figure
  • Straw, Hay, Dried Plants, Herbal Teas - Are Mostly Very Bulky Samples
    An average shopping bag contains 300 g straw or expressed like this: 100 g of uncomminuted straw take up the space of 1 to 2 litres. These materials are very voluminous. For the comminution only a cutting mill with a high rotor speed can be considered.
  • Intelligent Vacuum Controller
    load, the rotor speed "slips " slightly behind the rotating field. This small slip in speed generates an induced current, and the resulting magnetic field in the rotor produces torque.

  • Proceedings of the 9th IFToMM International Conference on Rotor Dynamics
    … with six proximity eddy current probes, four of which measure shaft displacement in two locations near the supports and two orthogonal directions (as in the real industrial balancing facility) while the other two probes measure the rotor speed and give a trigger …
  • Rotordynamics of Automotive Turbochargers
    The topic of rotordynamics of automotive turbochargers is a widely interdisci- plinary working field, first involving rotordynamics to study dynamics of rotating machines at very high rotor speeds as well as to balance the rotor.

  • Applied Intelligent Control of Induction Motor Drives
    The control strategies explored include expert-system-based acceleration control, hybrid-fuzzy/PI two-stage control, neural-network-based direct self control, and genetic algorithm based extended Kalman filter for rotor speed estimation.
  • Induction Motor Control Design
    It is a multivariable control problem since there are two indepen- dent control inputs and two outputs to be controlled: the primary output is the rotor speed to achieve the required dynamic performance, while the secondary output is the rotor flux modulus …
  • Limits, Modeling and Design of High-Speed Permanent Magnet Machines
    Through analytical modeling, structural limits for the rotor speed are determined and quantified.
