Features

Linear Actuator

The DGEA cantilever electric linear actuator from Festo Corp. (Hauppauge, NY) is designed so the slide unit remains stationary while the profile moves axially. Suited for space-contained, multi-axis configurations, the motor and cables remain fixed, minimizing the moving mass to just the load and aluminum profile. The toothed belt-driven actuator with an internal recirculating ball bearing guide comes in two mounting configurations: the basic, in-line coupling model, or with an integrated right-angle gearbox. The unit allows direct mounting of end effectors such as grippers, rotary drives, and vacuum components, and increases system dynamics by reducing the effective moving load. As the motor cables remain stationary, cable fatigue is eliminated. Features include speed to 3m/sec, stroke lengths to 1,000 mm, and 18-, 25-, and 40-mm sizes.

Contouring Control

The TNC 320 contouring control from Heindenhain Corp. (Schaumburg, IL) features the ability to control five axes, an analog drive interface for interfacing to existing drive systems, and one-piece construction, the device sports a 15" TFT color flat-panel display (1024 x 768 pixels). The unit’s main computer contains several onboard cycles to simplify most machining operations such as drilling, probing, and milling. The compact flash memory card withstands vibration and shock, stores the PLC program and commissioning information, and offers more memory for NC files. Data interfaces include RS-232, USB, and Ethernet. G-code programming is possible with the addition of a USB keyboard.

Ethernet Motion Control Card

Saelig (Pittsford, NY) offers the FMOD-IPDCMOT motion control card that uses an Ethernet bus to communicate data and supply power simultaneously at distances of several thousand yards. Via its integrated Web server, the unit combines a 32-bit motion controller and the speed of the Ethernet communication protocol. The card may be powered externally, as well as through an Ethernet cable at powers up to 15W.

Linear Drive

The TA330 linear three-phase servo drive from Trust Automation (San Luis Obispo, CA) is a 150-V, 900-W continuous (2700-W peak) linear drive. It can be configured to interface with any motion controller, including three-phase DC brushless servo motors using Hall Effect sensors, three-phase AC brushless motors using external sinusoidal commutation, single-phase DC brushed servo motors in bridged mode, and brushless linear motors. With low electrical noise, the TA330 is designed for integration in or near systems with noise-sensitive circuitry, such as sensors and transducers. It can be used with high-inertia mismatched stages and low inductance motors.

Belt-Driven Slide

The Voyager Series VB1 from Techno (New Hyde Park, NY) is a belt-driven slide that features lengths up to three meters and speeds up to five meters per second. Used for dispensing, inspection, pick and place, and parts transfer, the slide can be assembled to make two- and three-axis systems. It is available in 15 different travels from 200 mm to 3000 mm, with custom travels up to 5700 m also available. The slide comes with several types of motor configurations, including NEMA 23 and 34 steppers and servos, as well as a no-motor model. The slide also features a 50-mm-wide steel-reinforced HTD timing belt drive with a curvilinear profile to minimize slippage.

Gearmotor

The Model MMP-TM55-12V GP52-308 DC gearmotor from Midwest Motion Products (Watertown, MN) accepts any 12-V DC source including battery power. The unit has a diameter of 2.14" and a length of 7.75", with a keyed output shaft 12 mm in diameter by 25 mm long. Mounting is accomplished with 4 face mount M5 threaded holes, equally spaced on a 40-mm-diameter B.C. Output is rated for 35 Nm continuous torque at 15 RPM, and 70 Nm peak. The unit requires 7.2 ampere at 12 V DC to generate its full load output torque. Optional 24- and 36-V windings are available.
