Available with a Haydon size 17 stepper motor

Alongside precision couplings, gears and intelligent motion control, Reliance Precision Mechatronics, the UK distributor for Haydon Kerk Motion Solutions, a premier manufacturer of linear motion products introduces the MotoDrive^TM PDE Captive Linear Actuator which is available in size 17 single or double stack. The MotoDrive comes with an integrated chopper drive forming a compact system that is ideal for precision motion control applications.

The MotoDrive is capable of an output force of 220N (50lbs) for the single stack version and 350N (78lbs) for the double stack version. The captive configuration allows for a self-contained linear actuator unit with an anti-rotation device guiding a splined output shaft. The MotoDrive is ideal for applications requiring shorter stroke lengths (up to 2.5") such as precision fluid dispensing, throttle control and valve movement.

The MotoDrive can be programmed for micro-stepping with a step resolution range of 200 full steps per revolution to 12,800 steps per revolution when micro-stepping.

Optically isolated inputs of pulse, direction and enable signals are required for operation. The…

Thermo Electron Rely on Linear Motion Expertise from Reliance

Thu, 19 Nov 2009 11:16:00 +0000

Reliance of Huddersfield prides itself on providing continuous customer support throughout product life.

Thermo Electron has used Reliance’s linear products in their AA series spectrometers since 1999. As the product has evolved Thermo Electron has repeatedly drawn on Reliance’s linear motion expertise to help them achieve their specified criteria and maintain their accuracy requirements.

Thermo Electron’s Design Engineers first approached Reliance with an interest in using two leadscrews in their spectrometer design, one to control the prism rotation and the other to control the optical grating.

As the AA series developed the designers were also challenged with providing a mechanism for height adjustment of the flame. Engineers at Reliance were able to satisfy this requirement by designing in a screwrail.

With both the evolution of the product and the manufacturing world’s demand for higher quality yet lower price, Thermo Electron sought to simplify the spectrometer design. Once again turning to Reliance for support, the screwrail was replaced with Reliance’s new screw driven RGLS slide. These slides integrate a leadscrew and slide into one neat, space saving package providing an economical solution with fewer parts which also facilitates assembly and gives excellent robustness and rigidity.

The RGLS slide consists of an…

Reliance provides a full project management service, combining their facilities with their vast industry knowledge.

Mechatronic Tidal Simulation Assists Scientists

Mon, 07 Sep 2009 09:48:00 +0100

Scientists from London's Imperial College are using the new RT3 version of the Reliance Cool Muscle NEMA 23 integrated servo system to reproduce the sub-surface pressure changes created by lunar tides in laboratory research experiments directed at improving oil recovery.

The unique abilities of the RT3 version along with the support provided by Reliance allow the scientists to concentrate on the research without having to spend time controlling and verifying the test system.

The compact closed loop motor system has unique abilities to share I/Os, perform complex coordinated motion and use mathematical notation to perform motion. The onboard memory and logic banks along with the integrated tuners, vector drive, amplifiers, 32 bit RISC processor and 50,000 count magnetic encoder provide an intelligent motor which delivers cool running and smooth motion.

For this application, the motor moves extremely slowly and has been programmed to complete a 400mm long inverse cosine motion profile over a 12 hour 24 minute period using a 0.1" leadscrew. Using this feature the scientists are able to replicate the lunar tides found in underground oil reservoirs for their experiments.

Experienced Rotary and Linear Specialists Evolve

Thu, 17 Sep 2009 16:46:00 +0100

With more that fifty years experience in the design and manufacture of precision components, Reliance Precision Mechatronics LLP is now utilising this experience to design families of new motion control assemblies using their ingenious intelligent Reliance Cool Muscle motor with the latest in closed loop integrated motor technology.

These new assemblies include:-

The Reliance Cool Motion Slide - available in lengths up to 1.4 metres, these compact slides combine the high speed and linear accuracy of a screw driven slide with the intelligence of an integrated motor.
The Reliance Cool Muscle Racktuator® - a compact and lightweight linear actuation system with the option of solid or hollow racks.
Planetary Gearboxes - with interfaces designed to suit the Reliance Cool Muscle motor these units provide an economic solution where high efficiency, low backlash and long life are required.

The Reliance Cool Muscle Motor, available in NEMA sizes 11, 17, and 23, has unique abilities to network with other motors performing synchronised or simultaneous complex coordinated motion. In 2007 the RT3 version of the motor was released with the new capability of sharing I/Os and using mathematical notation to perform movement.

Reliance's attention to quality and accuracy is demonstrated…

New Range Geared Up for Different Accuracies

Tue, 08 Sep 2009 09:02:00 +0100

Accuracy across different budgets is the focus of the new comprehensive gear range from Reliance Precision Mechatronics LLP.

For a very economical balance of accuracy against cost, the brass spur gears in the range are designed for less demanding applications where accuracies up to ISO 9/10 are required.

Higher accuracy applications benefit from the choice of stainless steel and aluminium alloy precision cut gears or stainless steel fine pitch ground gears. The plain or anti-backlash precision cut gears are designed for long life and low torque transmission capabilities. The fine pitch ground gears go down to a 0.5 module and are accurate to ISO 5. These gears are easily tailored to suit interface requirements and offer higher torque transmission capabilities.

High accuracy applications can be supplied with either precision cut gears or fine pitch ground gears.

Quadrupole Mass Filters

Tue, 08 Sep 2009 09:09:00 +0100

Reliance Precision Limited has over 15 years experience in the manufacture of Quadrupole Mass Filters (QMF) for mass spectrometers. Over these years their facilities have evolved into a state of the art quadrupole manufacturing facility with experienced designers, clean room assembly, inspection and precision cleaning.

It is well known that the Quadrupole Mass Filter requires a very high degree of mechanical accuracy. Reliance has developed a computer model of the Quadrupole Mass Filter. This is used to evaluate the design of a Quadrupole Mass Filters against its performance criteria. Tolerance details for size, straightness, orthogonality, symmetry, positional accuracy, curvature, taper, and parallelism can be studied, and tolerances relevant to the customer's application may be stipulated. The model can produce details of ion entrance conditions, trajectories, and exit conditions, as well as representative mass peak shapes. Transmission versus resolution can be rapidly assessed for any design and in doing so, the optimum ion injection conditions can be specified.

The manufacturing processes are based around 12mm diameter electrode rods, dimensions and features of which can be produced to sub micron precisions. To match this, the mechanical dimensions of the parts and assemblies can be determined to within a few microns; often using…
