  • Getting to know stepper motors
    Fluid control and metering can often be more precisely handled by using stepper motors. EDITED BY Stephen J. Mraz Stepper-motor-based syringe pumps automatically dispense precisely controlled amounts of medications and solutions. Unlike an injection administered by a doctor that is quick and over
  • Stepper Motor Reference Design
    . Stepper motors are also found in industrial equipment such as robotics, electronic component handlers, testers, dispensers, and other manufacturing equipment. untitled AN155. STEPPER MOTOR REFERENCE DESIGN. 1. Introduction. timing. The low-pin count package has enough pins to. drive the stepper
  • Considerations for Step Motors in Space Applications
    Motors in Space Applications. The application of stepper motors in space is a design problem whose complexity is frequently underestimated. While most of the research in this field has focused on bearings and lubrication, there are a number of other issues to be considered. Richard Halstead. President
  • Linear stepper motors keep positioning in line
    to mechanically complex assemblies that require regular maintenance and develop inaccuracies over time. Dual-axis linear stepper motors are relatively simple consisting of a motor primary called the forcer, and a motor secondary called the platen. The forcer consists of four single-axis coil assemblies, two
  • Micro-Stepper Motors Bring Pictures into Focus
    breakaway torque. An additional pre-tensioning on the precision ball bearings by disk springs facilitates zero-backlash movement at torques of up to 1 N, a value which never actually occurs in practice. Mighty minis. Precision in the smallest of spaces. Stepper motors are suitable for many - even highly
  • Motor Control Software Examples
    Small motors, less than 300 W, are found in a wide variety of applications. These include automobiles, printers, copiers, paper handlers, factory automation, test equipment, robotics, space & military, and many others. The most popular small motors types are DC, Brushless DC, and Stepper motors
  • Brushless dc Motors in Medical Applications
    community. One reason: A life expectancy of 10,000 hr compared to a brushed motor life of 2,000 to 5,000 hr. * As an alternative to stepper motors, the top seed of BLDC motors is not limited by a large number of poles. Article: Power and efficiency drive motor selection, Article: Selecting dc brush
