Encoders for brushless motor commutation
The process of steering current through the appropriate motor windings in order to produce an output torque is called commutation. Before start-up permanent-magnet three-phase motors must have an absolute position value available for electrical commutation.
Positioning and speed control system for fifth largest telescope in the United States
Did you know that HEIDENHAIN components are within the new Discovery Channel Telescope (DCT) that has recently seen its first light at the Lowell Observatory in Arizona? As part of the DCT’s mount and control system developed by General Dynamics SATCOM Technologies (GDST), four HEIDENHAIN tape encoders ...
Did you know… – HEIDENHAIN DIEFFENBACHER
…that two HEIDENHAIN controls are an integral part of an unusual deep-hole gun drill machine now in place at Dieffenbacher North America hydraulic press manufacturer.
The TNC 640: High-end control for milling and turning
HEIDENHAIN is presenting the new TNC 640 at IMTS 2012. For the first time, milling and turning are combined in one TNC. The new TNC 640 is designed for machine tools capable of multi-operation machining.
Deep-hole gun drill machine for hydraulic press manufacturing
Two HEIDENHAIN controls are an integral part of an unusual deep-hole gun drill machine now in place at Dieffenbacher North America hydraulic press manufacturer. This deep-hole drilling machine has three spindles that can operate simultaneously over a 12000 mm table, enabling not only the manufacture ...
Retrofit new encoders on large, early 80’s multi-axis robot motors for motor manufacturing process
Did you know that HEIDENHAIN are the rotary encoders of choice in the “vintage” robot upgrades going on at Baldor Electric Company today? Having acquired four used, large multi-axis Fanuc robots five years ago, Baldor is currently installing Baldor drives and controls to make these useful ...
Maximum precision for a new view of the universe
Angle encoders from HEIDENHAIN for the world’s most powerful telescope By: DR. JOHANNES HEIDENHAIN GmbH, Traunreut, Germany ALMA does not use one single antenna for observation purposes but rather 66 receivers, precisely controlled and interconnected to form a giant telescope. Exact positioning of the ...
A wooden eyeglass manufacturer uses 5-axis machining to achieve low weight, no screws, unusual surfaces and perfect functionality
Did you know that a HEIDENHAIN iTNC 530 control is a vital component in the current manufacture of award-winning new wooden glasses, made by Rolf Spectacles? These unique glasses are growing in popularity, having their start in 2008 with three partners working out of a basement ...
Importance of mounting tolerances for modular encoders
Modular encoders are very susceptible to mounting misalignment. Since modular encoders have no bearing, they rely solely on the accuracy of the motor and encoder manufacturing process.
What influences accuracy of rotary tables?
When determining the influencing factors of accuracy on a rotary table, the first thing would be to look at the mechanics of the table itself.
