servo systems

What makes a bus based Motion Controller deterministic?   What are the three types of Step Motors?   What is the difference between an Absolute Encoder and a Resolver? These questions (and many more) are quickly answered Motion Control Technology Primer...

The LBR40 is a slim, stackable linear rotary actuator with a SMAC HT35 direct drive brushless motor. Encoder resolutions are available from 5 micron to 1um for application flexibility to optimize on position control.

A motion control system is a system that controls the position, velocity, force or pressure of some machine.  As an example, an electromechanical based motion control system consists of a motion controller (the brains of the system), a drive (which takes the low power command signal from the motion controller and converts it into high power current/voltage to the motor), a motor (which converts electrical energy to mechanical energy), a feedback device (which sends signals back to the motion controller to make adjustments until the system produces the desired result), and a mechanical system (including actuators, which physically produce the desired end result).
A motion controller is the primary intelligence, or brain, within a motion control system.  It is responsible for calculating and generating the output commands for a desired motion path or trajectory. Motion controllers vary in complexity; sophisticated motion controllers typically consist of a trajectory generator...

This document describes the evolution of motion and control system architectures and what new benefits are realized today when using EtherCAT®, whether for a large number of axes or simple systems using just a few. OEMs have many choices available and naturally gravitate to a given architecture in order to speed development and reduce costs. Machine systems, and mainly motion control, are normalized to meet the requirements of the application.
Highlighted too is not only the rise and acceptance for network connected motion control applications but also why they are here to stay. In fact, the continued demand for servo solutions like those provided by EtherCAT-based systems will grow faster than most others and come at lowered system costs to implement…

The key to reducing production costs is found in Cycle Time effects.  You may be able to further reduce costs if you look closely at the CT effects.
So what exactly are CT effects?

Fast and easy with just a few parameters.

A new web tool by maxon motor, the leading provider of precision drives and systems, is now available at selection.maxonmotor.com.  The “maxon selection program” (MSP) looks for appropriate drive systems that match the individual specifications of the user.  In the simplest case scenario, the user only has to enter the supply voltage, the load speed and the load torque of the application.

The MSP is seamlessly integrated into the online catalog and e-shop of maxon motor, which contains 2700 products (brushed and brushless DC motors, gearheads, sensors, controllers).  This means the user can select and order the suggested drive systems online from anywhere in the world, around the clock.

For drive specialists, the MSP provides an advanced search with additional parameters for specifying...

maxon motor provides effective help for drive selection.

The extensive collection with illustrations and descriptions includes formulae, terminology and explanations of the calculations that are relevant for drive systems.  A flow chart provides assistance in selecting the right drive for each purpose.
The Formulae Handbook lists the most important formulae in relation to all components of the drive system.  It makes use of a flow chart that supports quick selection of the correct drive.  Numerous illustrations and the clear descriptions of the symbols on the respective page make it easier for the reader to understand the formulae.
Roughly speaking, it is a collection of the most important formulae from the maxon catalog...
