Products Drives & transmissions Range of brushless DC motors with integrated drives expanded
Mclennan has expanded its range of precision brushless DC motors that feature integrated drives with the introduc- tion of a new five-wire version of the 24mm diameter KinetiX 24 EB from Allied Motion Technologies. Previously available with two-wire brushless control in clockwise and counter-clockwise versions, the new motor includes speed adjustment and direction reversal inputs plus an 18 pulse per rev speed monitoring output. With a nominal length of just 26mm, the compact motor design includes a low-cog outer rotor with an iron core for smooth speed performance whilst robust precision bear- ings allow high radial shaft loads. Available in 6, 12 or 24 VDC versions with rated power output of up to 2.7W, the motor specification includes a continuous torque output of up to 6mNm at a nominal speed of 4300rpm. The new KinetiX 24 EB complements a range of larger
integrated drive equipped brushless motors from Allied Motion and available from Mclennan. The complete range now covers diameters of 24mm, 32mm, 54mm and 68 mm, in two and five-wire control versions, that provide precision speed control for medical dispensing, laser scanning, high performance fans and pumps, and other exacting applications where fine motion control, long life and high reliability is essential. The brushless and contact free construction of the KinetiX 24EB ensures a long working life and the drive electronics include reverse polarity and over current pro- tection. For lower speed and higher output torque, Mclennan can supply this motor with a choice of spur or planetary gearboxes to suit application requirements. Further options include customised shafts, mounting flanges, winding and connector configurations.

Same day build-to-order gearbox service offered
Baldor has enhanced its fast turn- around gearbox assembly opera- tion, which now has access to an extensively-equipped machine shop, to the point where it can provide European customers with a same-day build service. Capable of building custom- configured power transmission
Best of bearings
NSK’s VS Series long-life spheri- cal roller bear- ings (SRB) have been developed
for vibrating machinery used in mining, quarrying and construction industries. The bearings are said to offer a ser- vice life more than twice as long as current designs, enabling vibrating machinery to operate reliably for longer, continuous periods.
The longer service life of the VS series SRB is the result of a special surface finish on the raceway of the outer ring, which is used to control the slippage action of the rollers. The curvature factor between the raceway and spherical roller has also been optimised. This reduces slippage and the initiation stress between the roller and the contact surfaces of the outer and inner ring raceways. NSK UK

products within hours of order placement, the new UK-based assembly line can produce high efficiency gearboxes and gearmo- tors in a range of models and sizes from the Dodge Quantis family. The Quantis product line is also interchangeable with most other leading gearmotor products for ease of replacement. According to Tristin Hurst, product manager for Baldor UK, “Custom gearbox assembly is a popular service with OEMs, end users, system integrators and system maintainers, but we have now raised the bar significantly. Any single-product order placed before 1pm will be available for
collection or shipment that day. The same policy applies for mul- tiple product orders which are placed before midday.” Hurst adds: “We are also now able to offer a wider range of gear- box input and output options, helping customers configure the optimal solution, and to apply special paint finishes such as cor- rosion-resistant epoxy. Baldor’s high-efficiency motors also make the service suitable for customers who need to comply with forth- coming EU energy efficiency leg- islation stipulating IE2-rated gearmotors after June 2011.” Baldor UK

WEG is meeting the demands for high efficiency operation across water and waste water treatment applications with its Wimes com- pliant W22 motors, said to be one of the most energy efficient ranges on the market today. The W22 Wimes line is avail- able in two versions, both backed by a three-year warranty, and both designed to exceed the requirements of the new IE2 (High) and IE3 (Premium) effi- ciency classes. Importantly, the IE3 Premium Efficiency versions of the motors are available now, in standard IEC frame sizes, well in advance of the next phase of the Energy using Products (EuP) Motor Regulations due for implementa- tion in 2015/2017.
Factory Equipment JULY/AUGUST 2011
The W22 Wimes motor line is said to offer users an unbeatable cost/benefits package, integrating a wide range of key features as standard. The motors have dual voltage space heaters terminated inside a separate space heater ter- minal box as standard equipment. The range is designed to lower total operational costs across the lifetime of the motors, maximis- ing value and minimising whole life costs. They are said to achieve these benefits through guaranteed energy savings, higher levels of productivity, and by deliv- ering extended lifetime operation with minimum maintenance, thanks to a design that minimises heat build-up, vibration and noise.

green industries Brevini UK has been working in the energy sector for many years and has a number of energy efficient products. The company has over a decade’s experience in the wind power industry where its slew drive gear systems are used to deliver high reduction ratios and torque ratings. It has installed 70,000 pitch and yew drives in the UK and the world, each of which has been geared to provide continuous and reli- able service for the life of the turbine. The pitch system is responsible for
controlling the angle at which the blades face the wind. Brevini’s plane- tary slew gear units provide an optimal solution for pitch drives for wind tur- bines up to the largest sizes considered today. The yaw system on a turbine ensures that the nacelle is always posi- tioned accordingly to allow the rotor axis to be aligned with the wind direc- tion for maximum energy output. Brevini slewing drives are again a suit- able solution for yaw drives. Brevini’s maintenance and repair team is able to service gearboxes up to 15 tonnes. Trained service engineers perform pre-strip-down inspections to identify work components; replace- ment parts are then sourced from the OEM returning drives to their original specification. Brevini is also taking a role in wave and tidal power for which compact planetary gear units are said to be suitable.
