Plans were drawn up for the construction of a bridge that would link the island to the mainland. That same year, it was announced that these new facilities would host the APEC summit in September 2012. A fast-track construction schedule was initiated resulting in the last section of the central span being lifted into place on April 2, 2012. The bridge is expected to be opened for traffic by July 2, 2012.

With Vladivostok being the largest Pacific port in Russia, the bridge had to be high enough to allow passage for any class of vessel. In addition, the Eastern Bosphorous strait is 1460m wide in the bridge project area. The finished bridge breaks numerous world records, rising more than 70m above the high water level, with a central span 1104m long. Pylons 320m high will hold stay cables 580m long.

One of the most demanding phases of construction was the assembly of the central span, made up of 103 panels, each 12m long, 26m wide, and weighing a total of 23,000 tons. The panels are aerodynamically designed to give the bridge maximum stability in the high winds for which the region is renowned. The panels were delivered by barges which were carefully positioned under the installation using GLONASS, a Russian global satellite navigation system.

Lifting the enormous panels from the barges to an elevation of 70m and into position was a precision operation taking about one and a half hours to complete. A special crane needed to be developed for this unique application. That development was put in the hands of the Mostovik Crane Factory, which specializes in the manufacture of large-capacity cranes for the most challenging applications.

A custom-designed Mostovik derrick crane was installed on the bridge center span deck, cantilevered over the nose and facing toward the strait. The crane was equipped with a wind gage, a lifting height indicator, and an indicator that shows precise panel position during the lift.

The application requirements for this particular crane were especially demanding. Not only would it have to lift and safely position panels weighing more than 300 tons each, but it would have to operate reliably in extreme temperatures. Winter temperatures in the region can drop as low as -30°C. To meet these requirements, Mostovik Crane Factory turned to Bauer Gear Motor, an Altra Industrial Motion company, for suitable geared motors.

Bauer supplied BF Series geared motors, with torques from 10100-13400Nm. Setting new standards for reliability, efficiency and economy, BF Series geared motors can be mounted in any required position – horizontally, vertically or suspended – to meet any application requirement. Total flexibility in mounting options includes shaft, foot, face and flange solutions. The motor terminal box can be mounted in alternative positions rotated in 90-degree steps around the motor frame, providing for unparalleled integration possibilities.

Generously dimensioned ball or roller bearings, case-hardened forged and ground gears, and internally and externally reinforced gearboxes ensure a long, low-maintenance service life. A hardened wear sleeve and spray ring at the rotor seal allow for reduced sump capacity, reliable lubrication and many years of leak-free performance.

For absolute reliability, the BF Series geared motors are completely enclosed and sealed to IP65 as standard (IP66 optional) against dust and water spray. Important for use in the Russky Island bridge application, the geared motors also provide comprehensive corrosion protection.

The compact scanning head of the ERO 6000 is made possible primarily by the application of a divergent scanning principle that does not require lenses or other beam-directing optics. The scale graduation is an extremely sturdy and high quality METALLUR graduation and is adhered very accurately to a steel hub. This scanning method is new in HEIDENHAIN angle encoders. The component’s resulting grating period is 20 µm, regardless of diameter.

Small scanning heads usually require small scanning fields, which are more sensitive to contamination due to the scanning principle. To counteract this characteristic, a signal error compensation function is integrated in the encoder’s scanning sensor, which compensates the amplitude size and amplitude ratio within certain limits and thus increases the reliability and safety margin of the device.

Two ERO 6000 design types with line counts of 9,000 and 18,000, respectively, are available. The encoders are available with 1VPP and TTL interfaces. When it comes to mounting, the disk/hub assembly can be centered mechanically via 3-point centering or electrically with a second scanning head.

First, the specifics. The reports anticipates an annual growth rate for the European integrated motor and drive market of 12.1% from 2010 to 2017. The growth is being projected on the basis of a demand for high efficiency and the need to reduce energy consumption, which together will spark more demand for integrated motor and drives across a wide range of industrial applications.

I got a few things out of the report. First, it struck me as one example of the interconnectedness of markets and industries because of how design variables such as expected efficiency and a concern with energy consumption, and therefore the need to create more energy-efficient systems and products, can drive product designs and trends in many diverse fields.

It also highlights how influential new energy conservation and efficiency standards issued by government agencies and countries are as drivers for industry design and business decisions.

At the same time, I wonder about the role of such forecasts; their impact on businesses and industries and the role they play in decision-making. We’re all well aware of how often rosy or even slightly optimistic (or pessimistic) projections turn out to fall far short of reality.

So what role do forecasts and projections play in your industry? Do you take them to heart or with a grain of salt? Let me know.

The key innovation is the patent-pending stator design, which uses a series of asymmetrical, interleaved laminations that are inexpensive to make, easy to assemble, and which fit together in a way that prevents the introduction of air gaps to the motor’s magnetic field.

The design also uses two separately accessible coils and several other innovations resulting in a compact, quiet, and durable low-power actuator. The VRAD-1510 uses a magnetic spring and pre-loaded precision ball bearings for improved durability. The design also precludes the need for mechanical stops on shaft rotation, all but eliminating noise, wear, and vibration, while enabling a wider range of potential applications. The range of shaft rotation is greater than +/- 60 degrees from the neutral position.

The actuator’s coils can be driven in series, parallel, or separately, opening up many options for how the device can be employed. For example, instead of using two coils to produce torque, one can be used for velocity sensing or dynamic breaking. The actuator also incorporates front and rear shafts, allowing multiple points of attachment or the use of an encoder or position sensor for closed-loop operation.

The VRAD-1510 is configurable to customer specifications of all key parameters, including torque factor, magnetic spring stiffness, coil resistance and inductance, shaft diameter and length, bearing pre-load, and temperature operating range. The VRAD-1510 has a rectangular-shaped stator with exterior dimensions of 1.5 x 1.0 x 1.5in.

The VRAD-1510, while conceived for use in high-speed laser scanning and lighting gear, is sufficiently versatile and low cost to be used across a wide range of electro-mechanical applications, including mechanical and automotive systems, industrial and commercial machinery, robotics, vending, HVAC, valve control, and other uses.

All motors from the AM8000 series need only one motor cable instead of the usual two. The otherwise necessary feedback cable is eliminated, since the encoder information is transmitted digitally via two cores of the motor cable. The single-cable feedback technology leads to a clear material savings and reduces installation and engineering expenditures.

The AM8800 stainless steel motor series is based on the Beckhoff AM8000 motor series. However, it’s been supplemented by an all-stainless-steel housing in AISI 316L, which was designed according to FDA guidelines, and a stainless steel motor shaft. The series encompasses three sizes, each with three overall lengths. The power range extends from 1 to 8 Nm standstill torque. In designing the motor, corners and edges were avoided; similarly, drill holes and screwed connections were largely dispensed with in order to prevent the accumulation of dirt. The motor flanges are implemented in B5 form and are compatible with the AM8000 series flanges, simplifying the conversion of existing plants and machinery.

Power losses have been kept low because of the optimum connection of the stators to the stainless steel housing. The motors are implemented without additional cooling and the thermal conductivity of stainless steel is approximately 14 times lower than the aluminum housing of the motor in its standard version. All AM8000 servomotors are equipped with a sensor for temperature monitoring, which passes the data on to the drive via the single cable. The data can be processed in the higher-level controller in such a way that the motor can be intelligently controlled in relation to its temperature, a useful function when processing easily perishable foods.

Equipped with IP 67 protection, optionally also in IP 69K rating, the AM8800 motors are even suitable for cleaning with high-pressure cleaners, which are commonly used in the food, chemical and pharmaceutical industries. Connection using ‘hygienically designed’ stainless steel cable glands ensures the permanent sealing integrity of the motors. As a special feature, the AM8800 motors can be provided with a sealing air connection in order to prevent the formation of condensation inside the motor. They can also be equipped with a holding brake or a multi-turn encoder, depending on the application requirements.
