The Reliance Cool Muscle servo motion control package combines an:

• Intelligent vector driver with a 32 bit RISC CPU,
• H-infinity tuner,
• A 50,000 count magnetic encoder,
• 0-3000 rpm high torque motor
• Power management

Into one intelligent motion control system, which allows a multitude of functions from just one motor.

Available in NEMA size 11,17 and 23, this neat all in one solution provides a lower cost complete ‘black box’ package, ideal for distributed control systems.

Reliance offers stepper motors with modifications to suit specific applications.

• Available in small quantities
  Units can be housed in special enclosures eg for vacuum / laser applications
• Connectors can be fitted
• Shaft and wire modifications are available on request
• Other wiring and performance options are available on request
   

Due to their unique miniature size, the linear actuator can be used to reduce size in applications such as precision dispensers, soldering robots, microscopic feeding, fine angular adjustment, rotation control and mirror movement.

The miniature actuator can also be ideal for applications demanding high speed and durability, such as compact high speed component conveyor systems, dose control and desktop robots.

The Racktuator® tubular rack actuator enables fluids, tubes or wires to be passed through the assembly, reducing the risk of entanglement, and keeping the system tidy. This along with the compact, lightweight design makes the actuator ideal for medical or scientific such as:

• Sampling machines
• Pick and place machines
• Dispensing machines
• Specimen analysis
• Reagent testing

Intelligent linear motion, accurate positioning, and long life in a compact assembly

The assembly combines the high speeds, linear accuracy and reliability of a screw driven linear slide with the intelligence of the Reliance Cool Muscle integrated motor

The Reliance Cool Muscle motor encompasses an integrated vector drive, amplifier, H-infinity control, 50,000 count magnetic encoder and a 0-3000 rpm high torque motor into one package.

Reliance Epicyclic Gearheads for the Cool Muscle Motor

The Reliance Epicyclic Gearheads RGP 40 and RGP 60 are designed to mount to the cool muscle motor for economical drive solutions in automation. The RGP series of planetary gearheads feature honed planet and sun gears increasing input speeds and reducing noise and giving a AGMA 12 + gear quality. All the gears including the ring gear are hardened, this allows for a high load ability, less wear and consistent backlash over the life of the gearhead. All our epicyclic gearheads have four planet gears as apposed to the normal three.

Reliance supplies precision gears, geared mechanisms and electro-mechanical assemblies to the aerospace, medical, biotechnical, analytical, scientific instrument and defence industries.

Reliance standard precision rack is produced by a thread grinding process which generates teeth of helicoidal form.

Manufactured in round, tubular and rectangular section Reliance rack can be used for both measurement and actuation.

Stainless steel, precision ball bearings to suit shaft Ø2mm to Ø10mm, ABEC 7 as standard

Plain and flanged, bronze and self-lubricating plastic bearings with up to Ø12mm bore

Reliance stainless steel fasteners are manufactured from A4-70 cold worked austenitic stainless steel, certified to a minimum of 700MPa tensile strength, while providing the best possible corrosion resistance.

Reliance offers three types of transmission system for use in engineering applications.

• Timing Belts and Pulleys - Application examples
• Cable Chains and Sprockets
• Link Chains and sprockets

Flexible shaft couplings are a crucial part of motion control assemblies. They are designed to provide accurate motion between two shafts where a small amount of misalignment exists.

Reliance precision lead screw assemblies are designed specifically for motion control applications where accuracy is paramount.

Innovative anti-backlash nut designs provide assemblies which are wear compensating with low frictional drag torques and excellent positional repeatability.

Including spline shafts, linear bearings and linear motion shafts

Spline Shafts provide anti-rotation for one axis motion or a drive mechanism with rotation for two axes of motion. They are designed for light to moderate load applications, where low cost, low friction, and long life are primary design considerations.

Reliance offers a wide variety of linear motion slides for engineering applications:

• Linear Motion Guides - Recirculating Ball Slide
• Screw Driven Linear Slides
• Precision ball slides
• Crossed roller slides
• Rack driven ballslides
   

 

 

Description

The ScrewRail® linear actuator includes a precision lead screw integrated within a guide rail, which drives an integrated nut. This assembly combines the seperate functions of drive and guidance in one single coaxial component.


The ScrewRail® eliminates the need for external rail-to-screw alignment and simplifies the design, manufacture and assembly of motion control systems. The combined design saves much of the space used by a two-rail system and is generally less expensive.
