More success stories from the most diverse applications which partners Micromech Systems and Parker has been supporting for food processing equipment and packaging machinery manufacturers. Form, fill and seal machine for coffee pads. The strong demand for coffee pads required increased product output as these single portion sachets represent a convenient alternative to conventional filter coffee that have become very popular. As a result of this high demand from the market, coffee producers were on the lookout for even better machines with a much higher throughput. The production process is technically demanding, as the pads must be formed from a strip of fabric, precisely filled, sealed and punched out.

A major advance in rotary table design was announced by Kitagawa at the recent EMO 2011 machine tool exhibition in Hannover. The Japanese manufacturer launched the first of a new generation of compact, low energy units that incorporate a high efficiency direct drive motor to achieve increased torque at lower power consumption.

The ubiquitous Intelligent Power Module, aka IPM, has been a mainstay in motor speed control designs. And with good reason: Such designs are relatively easy and cheap to implement. With onboard gate drivers, protection, and a six pack IGBT array integrated, it takes very little engineering effort to quickly come up with an effective design. Utilizing a stamped lead frame, plastic package, and high-volume components, and given an automated production line, the IPM has all the ingredients necessary to manufacture a low-cost component solution.

A new, comprehensive master data package for hydraulics now bridges the gap between fluid and mechanical design. More than 1000 new hydraulic macros in Eplan Fluid speeds up and simplify interdisciplinary documentation.

Designed to operate in dusty environments, the new MY34HYS range of hybrid stepper motors from Astrosyn International Technology produce very high holding torques of up to 8 Nm. The motors offer IP65 environmental protection thanks to their oil sealed front bearing and rubber sealed end bell and terminal block at the rear.

Nanomotion's new FBR60 piezo-electric miniature rotary stage is now from available from Heason Technology. Providing an exceptionally compact footprint and low profile for precision motorised rotary positioning, the stage has a 60 mm diameter rotating element and overall height of just 35 mm and features a high-stiffness cross roller bearing construction, twin piezo-electric motors that provide zero backlash direct-drive, and an integral non-contact optical encoder with micropositioning resolution options of 5 or 0.5 arc-sec.

The most important of the new characteristics are the extended angle of rotation up to 95°, a starting torque of up to 13Nm (gross starting torque at 20°C), an extended life time of up to >50 million cycles and extremely fast response time with switching times of < 5ms possible (depending on size and load)

Introduced by Micromech is the Kollmorgen new family of frameless, brushless motors derived from the proven and extensive portfolio of Kollmorgen designs. They are available in fourteen sizes for low or high voltage operation delivering torque, power and speed, within a cost-effective package and have a compact footprint. They give the system designer high flexibility in specifying a motor that fits the specific performance and dimensional requirements of the application but without incurring expensive engineering or other capital fees. Their advanced electromagnetic designs deliver maximum torque density which minimises required motor space envelope. They have extremely smooth rotation with minimal cogging, low total harmonic distortion (THD) and a broad operating speed range with rapid acceleration.

It is reckoned that more than two thirds of the total energy spend for industrial automation is consumed by electric drive technology and that an individual electric motor’s energy consumption makes up about 98% of its total cost of ownership over its average life. From these factors it is clear that investment in efficient drive technology is essential. The IEC60034-30 standard, making the IE2 energy efficiency class mandatory throughout Europe for a large number of electric motors from June this year, will begin to ensure reduced energy consumption on a global scale.

Midwest Motion Products is pleased to announce the release of a new DC Gear Motor, with integral failsafe brake, the Model No. MMP D22-376D-24V GRA60-032 BR-005. Accepting any 24 Volt DC source, including solar or battery power, this robust Gear Motor measures just 2.24” in Diameter, by 7.2” long, including the brake, and has a keyed output shaft of 14mm diameter by 25mm long. Easy mounting is accomplished with 4 “face mount” M5.5 threaded holes, equally spaced on a 52mm Dia. B.C.
