The device can be used to replace potentiometer-based angle encoders by combining position and motor feedback in one component or for low-cost servo feedback in rotary and linear actuators. Absolute position feedback is also very useful for machine homing. The device’s multi-turn option consists of an integral rechargeable battery, which maintains full position information for 20 hours if machine power is removed,

Rotalink designs and produces a variety of gearboxes in spur and planetary gearbox designs that feature polymer gears on ball or sintered bearings. The range also consists of ovoid-style gearheads, which include planetary gear assemblies for the output stages and a combination of spur gears for input stages. These are available in a choice of ultra-polymer materials.

The new absolute encoders are included in the company’s latest catalogue, which also features three new ranges of DC motor technologies – brushless, rare earth and heavy case – and new brushless version of the Red Drive motion controller and several gearbox lines.

The new Kollmorgen Automation Suite (KAS) has several key advances, which include a machine throughput of 200m/min, a more compact cabinet with a complete IPC module and total application development time of one week.

Compared with traditional machines, the new device eliminates the need to change the gearwheels and cylinders used for perforating or cross cutting several paper formats due to Kollmorgen’s AKM servo motors and precision gearboxes.

Customized formats can be used in the programmable control unit, while format changeover is performed at the touchscreen display.

“The crucial factor for the decision to go with the Kollmorgen Automation Suite was that the Motion Control, PLC and HMI/SCADA functionalities – in our case on an industrial PC – are available via a single processor. This standard tool allows the cost-effective introduction of company-specific knowhow and tailored solutions for individual applications,” said Jakob Graphic Services design engineering and technical manager. “Furthermore, it radically speeds up programming and commissioning, and increases machine performance.”

The new 2010 GAM Gear catalog includes information on: a new line of low-cost high performance planetary gearboxes (PE-Series), a complete new range of bevel-gear reducers with or without an integrated motor mount (VC-Series and V-Series), a new hollow-shaft-low-cost-hypoid gearbox (DL-DH), and 2 new flange-style gearboxes (right angle DS-DF, and in-line FP-KB).

The 2010 GAM Gear catalog also includes information pertaining to the Linear Slide Kit product (LSK). The LSK is a line of motor mounting kits designed to mount any motor or gearbox to any linear belt or ball screw actuator. The LSK range also includes a unique hollow-output-planetary gearbox designed specifically to mount to linear actuators. GAM provides all engineering and manufacturing for the mating kits and ships within 5 days from order.

The unique sensor system permits OEMs to monitor brush wear electronically in order to maintain uninterrupted operation of the PMDC motors or gearmotors. It also removes the guesswork in brush inspection and maintenance. Motors and gearmotors that are equipped with this feature can accommodate built-in EMI filtering and built-in magnetic encoder. The company is already in the process of searching for patent protection for this latest technology. PMDC gearmotors and motors that feature the proprietary design are exclusively available from Bodine Electric Company.

“This is the sort of value-added and innovative design engineering that sets Bodine apart. One of our customers approached us with the challenge of monitoring brush-wear and motor life in a battery- and solar-powered application. We took care of the motor solution with this new technology, and the customer integrated the sensor feedback into his control system,” said Terry Auchstetter Manager of Custom Solutions and Business Development of Bodine Electric.

The sensor system is best suited for remote monitoring of PMDC motors or gearmotors, especially when nobody is standing next to a machine all day.

“Many of our customers have had challenges developing and assembling brackets that connect motors and gearboxes to Festo® actuators,” said Craig Van den Avont, GAM Gear, LLC’s president. “We’re pleased to introduce a motor mount kit and planetary gearbox that comes ready to bolt directly to a Festo actuator.”

The new LSK from GAM is a customized mounting solution designed to connect any motor with a linear actuator. The LSK is also offered in multiple sizes and includes the mounting and coupling hardware.

The new EPL-H is a hollow output planetary gearbox that can directly mounts to any actuator and motor, and is offered in three frame sizes.

“We hope this universal solution will help make mounting to Festo actuators easier,” added Van den Avont. “We’re committed to meeting our customers’ needs as we strive to manufacture custom and universal solutions that make application design a more seamless process.”

• Technical data on the large SUMO hypoid gearboxes

All updated technical information can be found on product-specific pages at the Wittenstein website (www.wittenstein-us.com). Downloading the electronic version of the new catalog can be done from the Manuals page online.

Easy mounting can be achieved with four ‘face mount’ M5 threaded holes, which is equally spaced on a 40-millimeter diameter B.C. The reversible gearmotor’s output is rated for 310 Lb In continues torque at 2.5 rpm, and 443 Lb. In. Peak. In spite its compact size and weight of approximately four pounds, it is an efficient design, requiring only 0.2 Amps at 12 V DC to generate a Full Load Torque. This translates into a long life battery charge, which is very low in noise operation and lower in costs for related drive electronics. The motor windings for 90, 60, 48, 36, 28 and 24 Volts are also available. The unique design is rated at an IP 54 protection level for harsh environment operations. Variable speed can be achieved with Midwest’s fully compatible speed controls, Model MMP 20A-12V-RSP, or MMP 25A-12V.

Employing modern DSP technology which facilitates implementation of sensorless control algorithms and eliminates the need for position sensors (and associated wiring) required in conventional BLDC motor-control systems, Bison’s new low voltage AUTONOmotor™ parallel shaft gearmotors are offered in eleven standard versions with gear ratios from 5:1 to 215.6:1 and rated output speeds from 470 to 11 RPM with a 10:1 speed range. Speed can be adjusted with either a supplied potentiometer or a 0-5V DC signal. Continuous output torques range from 19 to 300 in-lbs (2.1 to 33.9 N-m). The gearmotors employ all-steel gearing, and oil bath lubrication for optimum design lifetimes.
