  • Pneumatic Motor - The Ideal Drive for Winding Processes
    of around two meters for example are wound at a high speed of up to 2000 m/min. Films are a sensitive material which must be wound or unwound very precisely. The winding of. metals on the other hand means that large masses are in play which influences the winding. process. Pneumatic motors are safe
  • R-Winding-Smoother, Quieter Motors
    Most step motor users are familiar with Series and Parallel connections; now, the patented R-Winding (U.S. Patent No. 6,969,930) has been created to reduce noise and vibration for lower-torque applications. Step motors typically run with a driver that either half steps or full steps. For example
  • Motor Starters
    . In addition to load demands, power company regulations may limit the current surge or voltage fluctuation that can be imposed on the power supply during motor starting. Many starters apply reduced voltage to motor windings; primary resistor, primary reactor, autotransformer, and solid state. Part
  • Encoders for Brushless Motor Commutation
    The process of steering current through the appropriate motor windings in order to produce output torque is called commutation. In brush motors, commutation is accomplished electro-mechanically via brushes and the commutator. In brushless motors, commutation is performed by electronically steering
  • AC Motor Overview
    Asynchronous motors and synchronous motors are the two main categories of ac motors. The ac induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary. The primary winding (stator) is connected to the power source and the shorted secondary
  • China ups the motor ante
    . "These are still mostly hand wound, " says Xia "because the labor involved is still cheaper than investing in the winding machinery. " As of now, there is very little custom motor manufacturing in China. The design capability isn't quite there yet, but this is already beginning to change. At a recent
  • Stepper Motor Theory
    motors incorporate a permanent magnet rotor, coil windings and magnetically conductive stators. Energizing a coil winding creates an electromagnetic field with a north and south pole as shown in figure 1. The stator carries the magnetic field which causes the rotor to align itself with the magnetic
  • Stepper Motor Control Using the PIC16F684
    between full steps and to improve the step resolution of the motor. Microstepping also This application note describes how to drive a bipolar improves the efficiency of the system, because the stepping motor with the PIC16F684. The Enhanced current in the windings of the motor is manipulated
  • Thermal Resistance For EAD Stepping Motors
    It is often necessary to calculate temperature rise of a motor in a given system. The following table lists thermal resistance for EAD size 17-42 stepping motors. Stepping Motor data generated with motors suspended in free air. Thermal resistance is given for motor winding to ambient.
