Lenze Three-Phase Electric AC Motors

Lenze Group's robust three-phase asynchronous motor with integrated motec frequency inverter can be conveniently matched to the required machine or process parameters. The compact motor, which features a high degree of protection, can be networked via a fieldbus and the digital and analog I/Os used for open-loop or closed-loop control.

As a result, it offers a wider range of potential applications. Lenze takes care of the cabling for you by installing the inverter at the Lenze factory. The decentralised concept minimises the need for shielded cables and saves your money. Many applications of Lenze three-phase AC motors require extra terminals in addition to the power connections of the motor, e.g. for the separate fan, thermal contacts, brake, etc.

The universal terminal box of Lenze three-phase AC motors offers a very convenient solution without intricate lamp-wire connectors. The terminal box has been expanded to include a small mounting rail. Up to 18 terminals can be connected to this rail, and all applications are thus possible. In addition, it is possible to include the rectifier required by the brake. Lenze three-phase AC motors are robust and applicable to many industry sectors.

The compact design and universality make these motors suitable for most applications. Lenze three-phase AC motors are distinguished by their modular design, which includes a universal terminal box, the easy installation of incremental encoders and resolvers. It is also possible to attach BFK458 spring-operated brakes for various applications. This Lenze AC motor program is rounded off by matching frequency inverters and attachable gearboxes.

Lenze asynchronous motors of the series 13.710 are compact and space-saving. Available in a power range from 12 to 90 W, these Lenze Three-Phase AC Motors are naturally ventilated. Since they do not have a fan they have low noise emissions and can be applied in production areas with fluff or dust. The motors are available with solid shaft and keyway, with flange mounting and can be fitted with a brake.

Good Causes Benefit From Staff Fundraising

Workers at Schneider Electric's Telford Site have raised over GBP 7000 for a number of good causes, including the company's chosen charity the NSPCC. Staff exceeded their fundraising target for the NSPCC donating over GBP 5000 towards helping vulnerable children in need in the UK. Over GBP 2500 was raised in a single event - the Telford town road race in conjunction with the Wrekin Road Runners.

In addition to the company's usual fundraising initiatives such as theme days, raffles and bike rides for the NSPCC, Schneider Electric Telford's money-making ideas have included getting involved in the Wear it Pink day for Breast Cancer Relief; two brave employees having their chests waxed for the Children in Need appeal; and getting involved in Jeans for Genes day that helps children with genetic disorders.

Julie Kane-Gblog of Schneider Electric enthused: 'The huge efforts of employees this year is appropriate for a company whose slogan is 'Giving the best of the new electric world to everyone, everywhere, at any time' and we are delighted to have raised such a large amount of money for deserving charities'.

Teachable Series 9000 Photoelectric Sensor

These new additions to the Series 9000 family incorporate the latest in ASIC technology, which when combined with the proven mechanical and optical package of the Series 9000 will provide the user with a distinct advantage for the most challenging industrial applications. Both new models have improved LED functionality; for example, a flashing green LED indicates an unstable condition such as lens contamination while a flashing red LED indicates a short circuit in the field wiring.

The 42GSP-9000 provides a teach function which eliminates the need to manually adjust the sensor’s sensitivity level. The manual adjustment potentiometer of the standard 9000 has been replaced by a single pushbutton which is used to initiate the “learning” of both the light and dark conditions presented to the sensor.

The 42GLP-9000 contains a manual adjustment potentiometer to adjust the sensor’s sensitivity level. As an enhancement over the standard Series 9000, the adjustment pot of the 42GLP-9000 provides a linear response to user input.

Both the self-teach button and the manual adjustment pot models, when combined with the new LED functionality, will drastically reduce set up time for installers and troubleshooting time for maintenance personnel. Additional features of both the 42GSP-9000 and 42GLP-9000 include:
Exceptionally high resistance to electrical noise and fluorescent lighting
Temperature compensation for environmental changes

Red Lion Controls Data Station Plus

Red Lion Controls Data Station Plus was designed to act as a nexus for industrial data collection and management. The unit offers multiple protocol conversion, data logging and remote machine access. With three built in serial ports and a 10 Base-T/100 Base-TX Ethernet port, the unit performs protocol conversion, allowing disparate devices to communicate seamlessly with one another. The Ethernet port supports up to four protocols simultaneously so even Ethernet to Ethernet protocols can be converted. The CompactFlash card allows data to be collected and stored for later review.

The files are stored in simple CSV file format allowing common applications, such as Microsoft Excel and Access, to view and manage the data. The free Websync utility provides a means to synchronize the files with a PC's hard drive for permanent storage. The CompactFlash card may also be used to load new configuration files into the Data Station. The built-in web server allows log files to be retrieved manually, and also provides access to the unique "virtual HMI".

The virtual HMI is programmed just like Regular G3 Series HMI. Any standard web browser such as Internet Explorer or Netscape may be used to monitor or control the HMI from a PC anywhere in the world. The USB port may be used for blazing fast file downloads, or to mount the Data Station's CompactFlash card as an external drive to your PC. The Data Station's DIN rail mounting saves time and panel space and snaps easily onto standard top hat (T) profile DIN rail.

Novel Thermal Design Reduces Inverter Volume

Lenze has developed 8200 vector inverters using the 'cold plate' technique for cases where the inverter can be mounted directly onto a substantial heatsink. AC Tech (Lenze AG) 8200 Vector Inverters are available for power 0.55 to 90kW with three-phase supply. In the more popular smaller sizes up to 22kW, a space saving variant can reduce the requirement for panel space by up to 40%.

By dissipating the heat outside the cabinet, these 'cold plate' versions enable panels to have higher enclosure ratings. Alternatively a plate with external cooling by liquid or air can be used. The cold plate versions of the 8200 vector inverters have no heat fins, so heat generated is passed to the mounting plate and transmitted out of the cabinet.

In this way inverters require less mounting depth and the space savings are substantial. For a 1.5kW inverter the saving is 25%, rising to 40% for a 22kW inverter. Therefore panels can be smaller and costs reduced. As the heat is now transmitted to outside of the cabinet, requirements for a flow of cooling air through the cabinet are removed. Cabinets can be sealed and protection to IP65 is easier to achieve.

This is particularly advantageous in dusty conditions where any through flow of air would cause a dust build-up. Above 22kW the cold plate design is not available. However an alternative 'push-through' design can be used right up to 90kW. Here the Lenze Inverter Heatsink is mounted outside of the panel, gaining the advantages of panel space and enclosure as described. The concept of the 8200 vector frequency inverter is based on a modular system of complementary components.

Combined with a Lenze geared motor or a Lenze three-phase AC motor, it can be used to implement electronic variable speed drives for a multiplicity of applications. Compact: Side-by-side mounting saves space in the control cabinet. Integrated filters (optional) simplify installation. Flexible: The modular structure enables the inverters to be optimised for your application. This results in cost-effective but high-performance drive solutions. Whether as a "stand-alone" inverter with setpoint selection via potentiometer or a networked inverter with speed feedback in master/slave mode, the inverter functions can be adapted to suit every application.
