Reliance has confirmed its exclusive European distribution and development rights for the Cool Muscle range of integrated motors.
Reliance has confirmed its exclusive European distribution and development rights for the Cool Muscle range of integrated motors.
Enjoying extremely close ties with the manufacturer, Reliance supplies bespoke subsystems which, with intelligent engineering, offer excellent value compared with alternative solutions based on standard components.
50,000 pulses per revolution and servo jitter less than 0.1mrad gives the Reliance Cool Muscle the smooth movement needed for accurate laser positioning, and the onboard power management system only delivers the power required for the job in hand, ensuring cool running.
The units have a maximum operating speed of 3000rev/min.
Simple and compact, with a unique blend of technologies, the Reliance Cool Muscle integrates an encoder, sensor, motor, motion control and driver electronics.
Using a vector drive with incorporated H infinity control, it provides a cost effective closed loop system.
The system's H infinity control accommodates a wide range of load variation during motion, responding to dynamic loads across the entire speed range.
This reduces the need to constantly tune gains, allowing higher inertia mismatches and providing increased motion flexibility.
The fully closed loop system constantly monitors position whilst onboard power management monitors and provides torque based on load, keeping the motor cooler than conventional stepper motors.
The unit's versatile control interface with multiple input capability: pulse (step and direction), analogue (0 to 5V), serial (RS232 and RS485) and PLC, provides an easily adaptable motion control solution.
Units are RoHS compliant.
Compact daisychain and multidrop topologies can be used to network up to 16 and 255 drives, respectively.
Reliance offers full application support for integration into complete mechatronic solutions.
Typical applications include: packaging and bottling conveyor systems, x-y positioning systems and pick and place mechanisms; laser positioning applications with servo jitter of less than 0.1mrad; and super clean environments - Reliance can supply units cleaned and sealed, ideal for cleanroom, optical, laser, food industry and medical applications.
