Based on a world power grid mix CO2 factor of 0.749 kg CO2/kWh, this translates to a reduction per solution of 4.4 tons of CO2 per year. Unlike rigid PV solar panel systems, the solar linear actuators increase power generation by 15 percent, on average.

“Harnessing renewable energy is one of the most effective solutions for reducing carbon dioxide,” said Mahdi Sebti, Global Segment Manager at SKF Renewable Energy, Solar.

“SKF’s advanced electromechanical technology offers improvements over today’s maintenance-intensive solutions and delivers high performance, accuracy and efficiency by accurately tracking the sun’s position throughout the day and throughout the seasons.”

The figures are applicable for 58 sq m panels equipped with an SKF Solar Linear Actuator, CASD-60. The results may vary depending on the size of the panel. Larger panel yields more environmental benefit since the actuator’s production and waste treatment does not significantly affect the results.

A part of the BeyondZero Portfolio product, the solar linear actuators seamlessly combine robust design, virtually maintenance free-operation, easy installation and reduced downtime to effectively reduce solar power generation costs while increasing profitability and productivity.

Specifically developed for 20-year service life, the CASD-60 solar linear actuators can withstand severe outdoor environments and are ideally suited for use in photovoltaics, concentrating solar power systems or concentrating photovoltaics.

Self-Locking Ultrasonic Motors, Direct Linear Drive, Direct Metrology Linear Encoders
The self-locking direct-drive motors in the M-687 positioner provide up to 10X higher positional stability. Because no holding current is required and there are neither leadscrews that heat up and drift during operation, no lubricant flow causing creep the stage is ideal for long term imaging applications. Linear encoders with 100 nanometer resolution provide direct position measurement with high accuracy. The compact design with minimized mass and inertia provides high precision bidirectional speed and position control, as well as very constant velocity, even at very low speeds. The drive system is based on the new U-164 Piezo Motor and outperforms the stability, acceleration and settling speed of traditional servo motor direct drives and gear-driven mechanisms.

Controller/Software Support
The microscope stage is delivered with a joystick and a proprietary piezo motor controller optimized to take advantage of the specific motion characteristics of ultrasonic ceramic motors. USB interfacing and a solid software and driver package for seamless integration are part of the package.

Compared to conventional worm and gear drives, the PSR300 rotary table rotates significantly faster and delivers higher equipment productivity and more accurate processed parts as it feature zero backlash with no vibration and gear wear.

Tested to 300 rpm continuous rotation of the traditional transmission based rotary table with comparable payload capacity and apertures, the rotary table employs direct drive brushless modular motor technology to maximize positioning performance. Aside from delivering high speeds and acceleration, this technology also has no gear trains to maintain and no brushes to wear, making the PSR300 rotary table ideally suited for applications that demand for smooth scan velocity, contoured motion and precise incremental steps.

To optimize performance with respect to rotation friction, wobble and moment stiffness, bearing with low run-outs are utilized, while a precision ground top rotor is employed to further reduce wobble.

The rotary table features sub arc-second high resolution encoder to ensure accurate positioning. Its motor and ring encoder are directly connected to a rotating shaft. The absence of mechanical couplings and gear trains effectively eliminates positioning errors attributed to windup, backlash or hysteresis. This enables the PSR300 rotary table to achieve a bi-directional repeatability of ±0.5 arc sec and an accuracy of ±5 arc sec.

The all-new system’s multi-component aspect delivers flexibility in mounting, configuration and installation, while its versatility opens up various potential applications, like providing positioning and movement for panels, screens and boards, or machinery, medical apparatus and manufacturing equipment.

Available in two different lengths, 47” and 94”, the corrosion-resistant aluminum track may be cut to the desired length. It can be mounted either flat, side or vertically. The track is ideal for applications requiring non-load bearing guide when mounted vertically.

The movement and positioning of the track is provided by its recirculating ball carriages. It can be inserted with multiple carriages, which can be used separately for independent movement or combined as a unit or both.

Carrying a maximum of 265 pounds, the load rating or 115RC linear track system based on the number and type of carriages fitted into the track.

It comes in two carriage options — the grease-free polymer ball offers clean and maintenance free operation as well as a quite and smooth movement, while the stainless steel ball carriage provides the highest load capacity.

To ease installation, the tracks feature drilling marks for both the end stops and fixing holes. Once installed, the ball carriages are then inserted into the tracks, while attaching the end stops to secure the carriage.

These encoders improve upon HEIDENHAIN’s already successful LC xx3 series, as the LC 115/415 now focus on the requirements for purely-serial absolute systems. This product introduction has opened with the safety-related purely-serial Endat 2.2 (up to 16 MHz) encoder version. Soon interfaces can also be paired with these encoders such as from Fanuc (ai), Siemens (DRIVE-CLiQ) and Mitsubishi (High Speed Interface up to 5 MHz).

The Functional-safety (FS) encoder versions are available for the EnDat 2.2 interface and in the near future DRIVE-CLiQ interface. This means that these encoders can be used as single-encoder systems in safety-related applications, such as in axes with a linear motor. In addition to safe processing of the position values, these encoders provide fault exclusions for the loosening of the mechanical coupling for various types of mounting.

As mentioned, the LC 115 features an optimized sealing design with two successive pairs of sealing lips. When compressed air is introduced into the scale housing, a very effective seal between the two sealing lip pairs is the result. This protects the DIADUR graduation inside, which is responsible for the positioning accuracy, from contamination by dust, chips and coolant.

The resolution of the LC 115 and the LC 415 with an accuracy grade of 3 µm was increased from 5 nm to 1 nm, compared to past LC xx3 series.
