  • DC Motors: Principle of Operation
    not require costly feedback devices. The linear stepper motor is similar to the rotational motor other than the shaft moves in a linear or lengthways fashion. Both types have two winding arrangements for their electromagnetic coils: unipolar and bipolar. Unipolar means that every coil end has one
  • Piezo Motors: Principle of Operation for Engineers
    How it Works. The Piezoelectric effect in piezoceramics converts electrical field to mechanical strain. Under special electrical excitation drive and ceramic geometry of Nanomotion motors, longitudinal extension and transverse bending oscillation modes are excited at close frequency proximity
  • Overview of Different Piezo Motor Design Principles
    rotary or linear motions. Methods of obtaining long moving distance. have various drive and functional principles that make these motors categorized into three groups: resonance-drive (piezoelectric ultrasonic motors), inertia-drive, and piezo-walk-drive. In this review,. a comprehensive summary
  • 5 Tips for Implementing an Integrated Stepper Linear Actuator System
    solution is also compact in size to allow for smaller equipment footprints. 1. Know the stepper linear actuator types. Figure 1. From left: Standard linear actuator; guided linear actuator; and leadscrew motor. The standard linear actuator (non-captive, internal nut) is configured with the leadscrew
  • Feature Article - New Developments in High-Speed Machining Technology - 03/03
    . The aim is to be able to move from point A to point B in the shortest possible time. These machines typically are horizontal machining centers with linear motor drives that offer rapid traverse rates of 100 to 120 m/min. and accelerations of 2 to 3g. Linear motors with their high feedrates
  • An Innovative Cabling Concept Improves Reliability for Multi-Axis Stage Systems
    requiring multi-axis stage systems. Usually an object has to move in two, three or more degrees of freedom (DOF) including linear movements, rotary movements, tilt and/or lifting operations. Parallel kinematic drives like hexapods can easily provide 6 DOF quite elegantly, but in most cases a simple stacked
