Dynamism for automation: the new LPA linear positioning actuators from Pfaff-silberblau

LPAs feature high speed, high duty cycles and high accuracy

Kissing, Germany, 21 September 2009 - Safety and reliability in the lifting heavy loads: those are the strengths featured by the products from Pfaff-silberblau Hebezeugfabrik GmbH with headquarters in the Southern Ger-man town of Kissing. Now, with the new LPA linear positioning actuator, this drive specialist is adding another characteristic to its product portfolio: dynamism. The LPA moves loads of up to 500 N at a speed of up to 30 m/min or 0.5 m/sec with a duty cycle of up to 90 percent and a repeat accuracy of ± 0.1 mm. At a reduced linear speed, it is possible for the LPA to handle a maximum dynamic load of 2000 N. The maximum permissible static load is 5000 N. Pfaff-silberblau specially designed this new linear drive for the automation industry, which requires high speeds combined with high duty cycles and absolute accuracy. At the heart of the new LPA is a hardened and spiral-toothed bevel gear system with a ball screw integrated in a high-quality aluminum housing. As a spindle, the LPA uses a ball screw with two alternative pitch variations: P = 05 or P = 20. In the standard version, the spindle has a class-T7 accuracy rating, which means that it has a pitch accuracy of 50 µ/300 mm. Optional versions are available up to a class-P5/P3 rating. The screw’s maximum axial play is – depending on the pitch – less than 0.05 mm. In the standard version, the LPA’s gear-mesh backlash is 10 to 15 angular minutes. However, there is also version available with a maximum circumferential backlash of < 6 angular minutes at the input shaft. Numerous different adapters for the end of the screw and numerous other options – as well as stroke-lengths that can be configured to match customer-specific requirements – make it possible to integrate the LPA into all kinds of applications. This includes use in materials handling technology, the packaging industry and assembly operations. Due to the use of high-quality lubricants and seals, the linear position actuator from Pfaff-silberblau requires little maintenance. The LPA’s optional positioning motor combines the motor, frequency con-verter and position-measuring device in a single unit. Consequently, in most cases, Pfaff-silberblau eliminates the need for the client’s portion of the construction to provide a programmable logic controller. The unit is de-signed for “plug and play” use. The motor is programmed with the aid of configuration and loading software designed to run on the Windows operating system. The LPA linear positioning actuator is just one of many new products at Pfaff-silberblau’s booth at Motek 2009. Together with its subsidiary ALLTEC Antriebstechnik in Hall 5, at Booth 5428, the company is also showcasing other developments. These include a new universal clamping fixture based on the ALSR model series, and special solutions from the versatile SHE series of worm-gear screw jacks, along with the TELESTO lifting column and the TARVOS linear actuators.
