INMOCO adds more industrial automation controllers
INMOCO has added seven new servo and stepper models to its popular MultiPro family of industrial automation controllers from Control Technology Corporation (CTC).
Brushless digital servos have SERCOS connectivity
Already 40% smaller than equivalent brushless digital servo drives, the Pacific Scientific all-digital PC800 range from Inmoco now offers more functionality, with SERCOS connectivity.
Inmoco told manufacturingtalk.com that these actuators are easy to integrate into machines.
They are compact, well protected and designed with two guiding systems, which make them robust and reliable in operation, said Inmoco.
The graduated Extrak design enables speeds of up to 1.6m/sec to be achieved using Exlar's linear guide rails; and higher speeds still, up to 5m/sec, using Exlar's innovative roller guide system.

Roller screws improve linear actuator performance
The new Exlar SR Series of linear actuators from INMOCO integrate patented roller screw technology with an integral brushless servo motor to provide high performance in motion control applications.
This enhanced speed capability allows the fastest index times along stroke lengths that extend to 7.6m.
Optional limit switch packages allow the stroke length limits and homing reference positions to be set within the physical limits of the actuator.
* Robust construction - the robust construction of the Extrak actuators enables them to carry oads up to 750kg.
Even higher loads are possible for intermittent duty service, said Inmoco.
The construction comprises a precision aluminum frame/housing with a movable platen.
The moving platen rides on one of the two different types of guiding system.
The first type incorporates a linear guide arrangement offering the highest load capacity and also the highest offset load, or moment capability.
Linear guide rails also assure high radial stiffness and vibration- free operation.
These criteria are important to assure both precise execution of motion profiles and extremely long operating life.
The alternative guiding system employs roller guides.
These are designed for lower payload capacities than the linear guide rails, but allow operation at very high speeds reaching 5m/s.
Extrak uses Gates toothed Power Grip premium belts to convert rotary driving motion to the high speed linear motion of the platen.
The belts also provides longer operating life, said Inmoco.
* Protection - an optional stainless steel metallic band seal provides comprehensive protection for Extrak actuators.
This is connected magnetically and covers the screw and guides helping to keep debris out of the drive system, which may otherwise eventually adversely affect the operation of the belt and guides.
In addition, all Extrak actuators can be supplied with pressure ports for applying positive air pressure to the actuator in extreme environments.
This feature provides additional protection against dirt and debris entering the housing and affecting the operational mechanism, said Inmoco.
* Used where space is limiting - unlike rod-style actuators, the extended and retracted lengths of the Extrak actuator are the same, permitting a smaller envelope for the actuator and allowing it to be applied in more space restricted applications.
The rodless actuators utilise a close-coupled motor mounting flange for mounting a choice of IEC or NEMA dimension motors, gearboxes, clutches, and brakes.
This allows the unit to be customised to specific application requirements with the smallest possible package.
The relatively small space envelope and the modular design of the Extrak actuators makes them easy to integrate into any machine.
The profile of the Extrak includes multiple sized T-slots which allow mounting to other commercially available extruded machine frame products.
These also offer mounting of multiple Extrak modules to each other for multi-axis systems.
* Different frame sizes - Exlar's Extrak actuators are available in three different profile (frame) sizes: 65mm; 80mm and 110mm.
The choice allows users to conveniently match the physical size allowed by your application with the required performance.
The modular design of the actuators allows the user to mount any IEC 60, 90, or 115mm frame or Nema 23, 34, or 42mm frame motors.
These motors are available from Exlar and can be mounted prior to shipment from the factory; including one version designed as a 'plug-and-play' component with a choice of servo amplifier.
Alternatively, the user can mount his own motor; in these instances Exlar will manufacture the adapter flange to the required dimensions for simple, close-coupling of the user's motor to the actuator.
The Extrak is supported by a range of accessories that allow adaptation of the actuators to specific applications.
These include: limit switches, limit switch cables, T-Nuts, mounting screws and additional travellers. Request a free brochure from Inmoco ...
