All-in-one motion package

All-in-one motion package
New from Reliance Precision Mechatronics is the Haydon Kerk MotoDrive 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 for the single stack version and 350N 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. With a supply voltage of 12 to 42V DC, the MotoDrive actuator functions with a run current programmable up to 2.6 Arms per phase. Optically isolated inputs of pulse, direction and enable signals are required for operation. The 'pulse' input is a square wave that sets the speed of the actuator. The 'direction' input is either a high or low signal using a +5V DC for shaft extend and ground potential for shaft retract. The 'enable' input is also a +5V DC signal that activates the drive for operation. Hold current on the drive is adjustable and can be selected as zero, 25, 50, 75 or 100 percent of run current using a jumper and associated pins located in a connector on the side of the drive.

Reliance Precision Mechatronics supplies precision motion control components and small assemblies to a variety of markets, including: medical, scientific, lab automation, photonics and aerospace. The company designs and develops market focused, fully integrated mechatronic assemblies.

The standard product range includes precision gears, precision ground rack, Reli-a-Flex flexible shaft couplings, leadscrew assemblies, tubular rack actuators, integrated motors and specialist stainless steel fasteners. Recent developments include additions to the coupling and gear ranges, as well as exclusivity in the UK for Haydon Kerk actuators and leadscrews.
