Our Cool Muscle range of integrated motors gives you everything you need in one high-density package. Every Cool Muscle motor has its own built-in drive and control. All you need is a PC with USB or serial port: use our free software to program Reliance Cool Muscle, then disconnect and walk away.
Closed loop control with the built-in 50,000 count encoder gives pinpoint command of position, velocity and torque throughout the motion profile. Connect up to fifteen Cool Muscle motors together for cooperative multi-tasking, multi-axis motion. Reliance Cool Muscle motors are packed with features to cut machine component count and save cost and development time. They have analogue and digital I/O on board, and RS232 and USB communications as standard.
Power-managed and energy efficient, Cool Muscle always stays cool.

RS485, CANopen, DeviceNet, PROFIBUS and Ethernet cards are available as options for the RCM servo systems. Our engineers provide technical support based on extensive experience integrating the Cool Muscle with third party controllers, HMIs, and PLCs.
Designed specifically for the RCM, this power supply is built to withstand the current draw spikes which the hard stops or starts often require. Specification of the power supply is 150W/300W, 6A/10A.
A standard motor cable (40cm) is supplied with every motor. Longer motor cables are available as an option. A Y-cable is required to connect the RCM to a USB or serial port.
Multi motor custom cables can be made to suit your application.
Conventional motion control requires expensive drives and controls. Additional wiring for origin and limit switches increases complexity and cost.
Cool Muscle eliminates the need for separate drives and motion controllers. It uses current sensing to detect limits with no need for switches and sensors.
Based on a 32-bit RISC CPU, the integrated controller is fully programmable. Take advantage of a wealth of built-in software features to program quickly and effectively. Start programs from a PC, PLC or simple push button.
If your application requires complicated or arbitrary motion you can send commands to Cool Muscle from your PC or embedded computer.
Connect up to fifteen Cool Muscle motors together with RS232 to form an integrated, low-cost system. Use optional communications modules to add Cool Muscle to your Ethernet or PROFIBUS network.
Cool Muscle has built-in analogue position and velocity control, or you can take advantage of Cool Muscle’s A-to-D conversion in your own programs.
Replace your existing Pulse/Direction or CW/CCW drive and stepper motor with a P-type Cool Muscle for complete freedom from step-loss. Transparently add closed-loop position and velocity control for smooth, 100% reliable positioning.
An intelligent driver with a 32 bit CPU based motion controller, driver amplifier, magnetic encoder and power management are all built in right on the motor.
The Cool Muscle is a fully closed loop system. With a high resolution magnetic encoder and the intelligent driver board mounted on the back, the Cool Muscle constantly monitors its position, eliminating any missed steps.
Using the newest control technology, the Cool Muscle goes beyond old fashioned static PID control by utilising the robust H∞ control system. H∞ responds to dynamic loads across the entire speed range, reduces the need to tune gains, and increases the allowable inertia mismatch.
The Cool Muscle's high resolution encoder gives you an exceptionally fine placement of 50,000 units per rotation. The Cool Muscle uses Vector Drive Control, resulting in incredibly smooth motion, even at low speeds, not possible with microstepping drivers.
Vector Drive is a control technique used in servo systems. Vector Drive Control is a completely different technique from micro-stepping. Unlike micro-stepping Vector Drive Control is not subject to resonance problems, produces smooth movements, increases torque and increases efficiency.
The Cool Muscle's power management monitors and provides the optimum current, based on load, keeping the motor cool. In addition, using a stepping motor, the Cool Muscle generates high torque at low speeds.
Program the Cool Muscle to create the motion you need. Define motion profiles and create programs using easy-to-understand Cool Muscle Language (CML). Motion programs you create can be downloaded to the Cool Muscle. The programs can be executed via PC, embedded computer or simply using I/Os.
Cool Muscle Language is a set of ASCII commands which lets you create motion programs easily.
Configure and assign multiple functions to I/Os on the Cool Muscle. Cool Muscle has 4 inputs and 2 outputs that can be used as digital, analogue, serial or pulse counter (Input only). The new Cool Muscle lets you assign a function to each point of a signal.
The Cool Muscle provides you with different networking solutions that best suit your needs. Connect multiple Cool Muscles in a daisy chain style network. In the daisy chain network Cool Muscles can tell other motors to activate programs as well as receive commands from a computer or an embedded controller.
Change speeds or accelerations while the motor is in operation. The Cool Muscle supports advanced motions such as continuous PTP and PTP motion with different accelerations and decelerations, push mode and more. The powerful push mode is also standard allowing for electric simulation of common pneumatic operations.
Eighteen Reliance Cool Muscle motors were recently used by Labman Automation Limited, laboratory and industrial robotic solutions specialist in their new automated bottle inspection system design.
Bottles travel to one of nine test stations and are photographed and weighed to check bottle condition and filled volume. Passing these pre-requisite tests the bottles are barcode scanned and a Cool Muscle motor lowers a mechanism to check the cap tightness and to tighten the cap, if necessary. All tests passed, the bottles travel into the main bottle handling system.
