The new MCA range of brushless maintenance-free servomotors comprises 19 models across frame size 56 to 112, with a choice between natural ventilation and forced cooling. Standard options are brakes, resolvers, encoders and plug or terminal box connection. Enclosure is to IP54 but can be readily upgraded to IP65 on request.
Compared to synchronous motors, asynchronous models are more robust and the MCA series has particularly high overload capacities from five to more than ten times nominal torque.
Costs are lower as the construction does not use expensive rare-earth magnets.
Sizes are generally larger which leads to higher inertias and a performance that is less dynamic but still suiting most applications.
A further advantage is the ability to run at high speeds through field weakening, up to 8000rev/min on the MCA range.
Rated output torques range from 2 to 55Nm at speeds of 2000 to 4000rev/min.
The addition of a rear mounted blower increases the torque on a given frame size by a factor of two or more.
Lenze offers UL conformity as standard for the North American market, and a full range of pre-assembled system cables to speed installation.
An almost infinite range of solutions can be specified by combining MCA motors with Lenze G-motion gearboxes.
These include inline planetary gears with rated outputs up to 1000Nm, as well as helical and right-angle bevel designs.
Gear ratios are possible between 1.6 and 412.
Many combinations can be built from stock parts for fast delivery, and low backlash of typically 6-10arc-min is available.
Plastic bearings offer automotive alternatives
Igus (UK) can provide a multitude of high-performance plastic bearing alternatives for the automotive industry. Igus tailor-made materials and solutions deliver a longer life at a lower cost with bearings designed for specific automotive applications, including: convertible tops; door hinges; chassis (shock absorbers, brakes and control arms); seats (lift links, headrests and gears); windscreen wipers; steering systems (both shaft and column); foot pedals; gearboxes; and engine compartments (variable air intake, EGR, belt tensioner and throttle valve). Igus' Iglidur suite of plastic plain bearings offers customers the choice of more than 6000 imperial and metric bearings from stock.
Iglidur plastic bearings are a convenient, cost-effective alternative to bronze, metal-backed and custom injection-moulded bearings.
All Iglidur bearings are self-lubricating and maintenance-free.
The plastic-based construction eliminates corrosion and delivers better vibration dampening than metal bearings.

Lubricants save money at brickworks
A success story for Sovereign Lubricants and Seals concerns the manufacturing of bricks and the associated machinery that is subject to harsh conditions. All companies involved in this business experience the same problems with machinery wearing out quickly due to poor or inadequate lubrication, A brickworks that has been using Omega since 1983 has proven that quality lubricants make a noticeable difference to wear and tear on plant and equipment and in turn increase productivity results. The brickworks first started using Omega 690 gear oil in January 1983 and after trials is now running Omega 690 in most of its gearboxes.
There are hardly any failures these days and the firm saves about 10% on energy.
The boxes run quieter and the oil lasts longer.
For the past 23 years, the brickworks has used Omega 71 high temperature grease in its kiln fan bearings, which are subjected to extreme heat.
The product has let the firm save on maintenance costs.
It also uses this product on its screen bearings which are in a very dusty and wet environment.
It had big problems finding a suitable high temperature lubricant for its kiln car bearings for many years until Sovereign introduced it to the Omega 35 in November 1994.
This product has been a success in handling the very high under car temperatures.
Sometimes the temperatures are as high as 350C in certain hotspots and this would melt or harden other greases and the bearings would seize.
Now it only uses 10kg of Omega 35 per year to grease all its kiln cars, saving thousands of pounds per year in staff hours and cost of grease as it only greases once per year.
It has also saved money on not having to replace seized bearings.
Finally, it uses Omega 73 on all its open gears.
The Chief Engineer at the brickworks, which is based in South Yorkshire, said: '23 years of satisfaction'.

Rotary actuator range expands its coverage
applications where dynamic force demands are below 100Nm. Conversely, the Model 17 is a modular maintenance-free design engineered for high torque, high load environments.
Application potential for both designs is wide and varied.
For example, the Crab 17 has been adopted by the electricity supply industry.
Manufactures of high power switching gear are using the actuator to provide the motive power for high reliability, remote controlled motorised switches, which automatically ensure distribution continuity by bypassing line faults.
Model 05 rotary actuators result from the development of a new, patented Swedish seat recliner technology, which has been successfully applied in the automotive industry.
Car seat applications demand low cost, high impact strength and easy operation (electric or manual).
Also, for reliability, they require minimum moving parts and a lubricated-for-life design.
To meet this design brief, the 05 actuators comprise two planetary gearboxes, which provide a final gear ratio equal to their difference.
Thus, high ratios can be achieved with a simple design and few moving parts.
As standard, Crab 05 units feature chrome-plated steel components which suit dry, indoor applications.
However, for more demanding environments, SKF can manufacture customised solutions.
Model 05 actuators are primarily designed for exposure to torque.
Key specifications include: a maximum static output torque 800Nm (flange) and 40Nm (sun gear); maximum dynamic output torque 100Nm; maximum radial force 200N; gear ratio 56:1 or 57:1; and maximum input speed 300rev/min.
Operating temperature range is 5 to 40C.
Moving to the Crab 17, priorities switch to design flexibility and modularity within a compact, high torque, high load unit.
Regarding flexibility, in addition to a wide choice of standard motors, gears, connectors and output shaft configurations, customers can also opt for bespoke elements such as custom machined outputs.
Model 17 actuators can be used as load-bearing elements of machine designs without the need for additional bearing arrangements.
The aluminium housing is prelubricated, sealed-for-life and maintenance-free.
Requiring just four mounting bolts, the actuators can be used in extremes of temperature and humidity.
Specifications include: maximum instantaneous output torque 200Nm; maximum axial load 5000N; maximum angular speed 180deg/s; and backlash +/-0.25deg

Geared motors excite packaging machine makers
Lenze is an official distributor for Panasonic, one of the largest motor manufacturers in the world. Panasonic developed the G-series range of geared motors which cover powers from 6 to 90W. These units are now established in the worldwide market with a reputation for quality, value and long life.
The PPMA show held in September 2005 at the Birmingham NEC proved the popularity of the range with many of the displayed machines using the G-series range.
The G-series range of geared motors are designed for single- and three-phase supply, the single-phase units are suitable for fixed speed running in a power range of 6 to 90W.
The three-phase motors ranging from 25-90W have two versions, 230V ideal for variable speed control with an inverter and the 400V version designed for fixed speed running.
All 6 to 40W models are all self cooled, and the 60 to 90W units are supplied with a cooling fan.
The G-series geared motors are available as standard induction, quick reversible or braked motors.
Standard induction motors are highly efficient and quite in operation.
The same high quality design and basic construction is used throughout the range.
All motors are four-pole with a nominal speed of 1500rev/min at 50Hz.
Quick reversible motors have a plate attached to the end of the rotor which is constantly under friction via four cylindrical brake pads and springs.
The resulting braking torque is continuously applied to the motor even during motor running.
When power is removed, this friction results in faster stopping of the motor.
The brakes in the braked motor models release when power is turned on leaving no residual torque, so when the motor is switched off the brake engages.
The gearboxes are available in standard ratios of 3:1 to 200:1 and use a combination of helical and spur gears for high speed efficient running.
Where high rations and lower speeds are required, an intermediate decimal gearbox is available.
If variable speed is required the 230V three-phase geared motors can be used with the Panasonic Micro-Inverter.
This combination offers excellent speed/torque characteristics and good dynamic motor performance.
Other inverters with higher functionality can be used, for example the Lenze smd with its unique memory chip which contains the entire drive and motor configuration and can be easily removed and replaced for fast and efficient program changes, saving time and money.
With the G-series suitable for conveyor, food machinery, packaging, pumps, labelling and test equipment applications, it's no wonder that many of the packaging industry's top manufacturers include the G-series in show machinery.
