Stepper motors can offer servo performance

Edited by the Manufacturingtalk editorial team Apr 4, 2006

A stepper motor drive from a Canadian designer and manufacturer of advanced motion control technology brings servo motor performance to conventional stepper motor systems.

LG Motion's inaugural UK exhibition following its launch last year is set to show the wide range and diversity of motion control and positioning systems available from this new UK manufacturer and distributor.

Visitors to stand D37 will see the launch of a breakthrough hybrid technology for stepper motor drives from Agile Systems along with positioning system solutions from the UniSlide and BiSlide ranges as well as LG Motion's own range of LG series precision tables.

Details of a new agreement with Schneeberger for a rapid turnaround cutting service for linear motion guide bearings systems will also be announced.

The SILENTstep stepper motor drive from Agile Systems, the Canadian designer and manufacturer of advanced motion control technology brings servo motor performance to conventional stepper motor systems.

A unique patent-pending technique derives position feedback from back-EMF and phase current sampling without encoder feedback and eliminates motor stalling, reduces audible noise, and increases motor speed.

LG Motion will demonstrate how the SILENTstep drive technology can be applied to new and existing position control applications improving performance whilst maintaining the simplicity of a conventional stepper motor drive system.

Other products on display from Agile Systems will include the DPDLite sensorless motor commutation system for brushless DC motors and the uMAXB series, FireWire networked, DSP based single-axis motion controller with integrated servo amplifier.

Working examples of the wide range of Unislide and BiSlide positioning tables will also be on view.

Aimed at medium precision positioning applications and available with manual and motorised versions, the UniSlide is a long established, simple, strong and durable design based upon a unique rigid dovetail bearing system in a lightweight aluminium construction.

The BiSlide range is aimed at heavier duty motorised applications and based upon an extruded I-beam aluminium profile with dual 45 deg opposing guideways that provide maximum rigidity regardless of the load direction.

Both ranges are available in single and multi-axis configurations with a wide range of options and accessories.

LG Motion designs and manufactures its own range of linear and rotary positioning tables for high precision applications and a selection from the new forthcoming catalogue will be on display at the show.

Following a newly signed UK distribution agreement, LG Motion will also show a selection of products from Schneeberger Linear Technology, the renowned Swiss manufacturer of linear cross roller bearings and slides and 'Monorail' profiled linear guideways.

Whilst LG Motion have been building Schneebergers' linear bearings into their custom engineered positioning systems for some time, the agreement will allow a new stocking and a rapid turnaround cutting service for Schneeberger linear guideways where customers can order custom lengths and be assured of delivery within two working days.
