Dynamic linear motors provide flexible modular design

sensitive electronic equipment such as ac drives to malfunction. Frame size 12 has two rectifiers as standard, enabling a 12-pulse supply connection that greatly reduces the most harmful harmonic currents. It also uses the latest microprocessor technology and Insulated Gate Bipolar Transistors (IGBT) technology to reduce EMC/RFI emissions and allow for longer motor leads. Innovative techniques enable IGBTs to shut down rapidly when external faults are detected. Anthony Pickering, President of Control Techniques, said: “Our new frame size 12 drives mark a bold new direction for Control Techniques, enabling us to provide a high quality, high power system to a new world of applications and industries. “As these new drives are effectively an extension of our Unidrive M range, users can be confident they are getting a product that is built with exceptional levels of performance, durability and flexibility in mind. “Effective, working machinery is critical to all businesses. For a business that runs its machines 24/7 downtime has a huge, negative effect that runs through the entire production process. What if long stoppages become a thing of the past? “Frame size 12 enables on-site repairs to be carried out if necessary and replacement emergency breakdown units can be available in as little as 24 hours. “This is our largest ever drive and one of our simplest to commission. People around the world know and respect us for our smaller drives, so we’re excited to introduce our large drive.” For more information contact Control Techniques.

The only change will be on the nameplate of the motor itself, from BAUER to ALPHA. “Our aim is to clearly align the brands of our electrical products, com- pared to our power and transmission products, with these two distinct brands,” Barnard notes. BI has a wide range of aluminium frame electric mo- tors and aluminium housing three-phase asynchronous motors, all with the latest design and selected quality materials that conform to the IEC standard. The MA range of BAUER motors performs well in even the toughest environments. This range has been designed to deliver reliable performance and is easy to maintain. With a 0.18 kW to 7.5 kW output, the motors are lightweight and have low noise levels.

Backed by its wealth of expertise in the development of rotary servomotors, Beckhoff has added an innovative product to its portfolio of drive technology. This new generation of high- performance and modular linear motors was developed in cooperation with Fertig Motors, a growing Beckhoff subsidiary. The new AL8000 product

With optimised product design the new AL8000 series linear motors achieve high peak forces in the smallest mounting spaces.

family is based on a modular system design consisting of linear motors and magnetic plates. Users can choose from three widths: 50 mm (AL8x2x), 80 mm (AL8x4x) and 130 mm (AL8x6x). In addition, each width category offers a broad range of different linear motor types in terms of overall length, type of winding and cooling type. The standard product portfolio thus contains 28 different linear motor types to implement highly dynamic and powerful linear axes to suit specific application requirements. Depending on the size of the linear motor, peak forces of 120 to 6 750 N are possible, and maximum speeds of up to 12 m/s. Like the established AM8000 rotary servomotors, the AL8000 family of linear motors is fully developed and manufactured in Germany. A consistently high level of production quality is therefore guaranteed as well as high availability and short supply chains to realise durable and reliable applications with linear motor technology. Further advantages include service and support, ensuring fast and flexible responses to customer requirements. Modular coil design In keeping with the modular system principle, the entire linear motor coil part is composed of individual, identical segments. This construction is especially favourable from a production perspective. Depending on which linear motor is ordered, the production process can be adapted quickly and easily to accommodate the relevant number of segments. Yet another advantage is the precisely symmetrical structure of the linear motors. There are uniform intervals between the mounting holes of the linear motors throughout the AL8000 series. This makes it easier for machine manufacturers to construct the machine slide and ensures consistent force and temperature distribution within the motor without critical hot spots.
