  • Linear Encoders
    A typical linear encoder consists of a scanning unit and a scale. The scale is generally glass and is cemented to a support, usually an aluminum extrusion. The scanning unit contains a light source, photocells, and a second graduated piece of glass called the scanning reticle. This scanning reticle
  • Linear Motor Basics
    transmission components, there is no backlash. Resolution considerations do exist. That is the linear motor must be displaced by 1. feedback count before it will begin to correct its position. ยท Maintenance Free Operation: Because the linear motors of today have no. contacting parts there is no wear
  • Linear Actuators built for Hazardous Locations
    GSX linear actuators from Exlar Corp., Chanhassen, Minn., are available with CSA Class I, Division 2, Groups A, B, C and D certification. This means they can be used in places near flammable gases and vapors. Linear Actuators built for Hazardous Locations | Exlar. Exlar. Exlar Products. Complete
  • Encoder vs. Resolver-Based Servo Systems (.pdf)
    all parts of the machine in step at a given pace. Electronic motion controllers use devices called transducers to accurately resolve and encode the position of a motor. shaft, other rotating shaft, or linear movement on a machine. Through the history of machine development the com-. mon names adopted
  • Linear Actuators Support Weapons Elevator
    components. EGSM30 linear actuators from Exlar Corp., Chanhassen, Minn., were selected to fire locking pins to keep the elevators in position at each deck level. The actuators combine a brushless servomotor, inverted roller screw, and an encoder/resolver into a single compact assembly. The brushless
  • Linear Motors Offer Precise Positioning and Highly Dynamic Response for Many Motion-Control Task
    of linear motors to suit a wide array of applications. Siemens, for instance, offers three models that work with all Sinumerik or Simotion controls and Sinamics drives. Linear scales for position and velocity feedback are available from third-party suppliers. 1FN3 peak-load motors have high
  • Application Note: Position Feedback Device Comparison (March 2003)
    shift proportional to the position of the rotor. This is very much like a "linear" resolver. These devices are very accurate and more expensive than resolvers or encoders. Glass Scale - similar to an encoder except it is a linear device. A glass rod is marked with a series of transparent and opaque
  • Positioning Components
    and incremental types. Incremental encoders typically generate a pulse for every increment of motion over which they travel. To gauge position, a controller counts the pulses. The most common incremental encoders are rotary optical encoders, linear optical encoders, and linear magnetic encoders. Other types
