Bis Automation, Inc.

Drives Covering 0.125HP to 1,000+ HP and from general purpose variable frequency to flux vector control, Yaskawa offers the most reliable line of inverter drives in the industry. Our family of drives is ideal for applications ranging from fans, pumps, conveyors, cranes, extruders and winders to complete steel processing, papermaking/coating and textile systems. Yaskawa's line of machine tool spindle drives and motors offer both high speed and high performance. Yaskawa / Magnetek General Purpose AC-Drive 50 Years of AC Drive Technology Fifty years ago, MagneTek provided adjustable frequency drives in the form of variable-speed-driven alternators. In the �60s, MagneTek introduced solid-state thyristor inverters to replace the alternator, significantly reducing the cost of adjustable frequency drives. In the early '70s, we introduced the first commercially-available Current Source AC drive. Although there was a price premium, AC drive performance was unmatched. This drive embodied the fundamental control concepts found in today�s vector control drive. Throughout the '80s, PWM technology improved, both in performance and reliability, and in the late '80s, MagneTek brought one of the most advanced microprocessor-based PWM AC drives to market. In 1990, MagneTek introduced the IGBT-based GPD 503 with instant success and dominant market position, followed by the VCD 703, flux vector control drive. Now, MagneTek introduces the next technological achievement, the GPD 515. Backed by 50 years of continuous advancements, the GPD 515 utilizes state-of-the-art IGBTs, SMDs, ASICs, 32 bit processing, motor algorithms, auto-tuning, and other benefit-laden technologies creating the cutting edge in AC drive design. The most spectacular achievement is the flexibility provided to our customer, with a single drive platform offering traditional V/Hz, sensorless vector, and flux vector control performance. Combined with MagneTek�s inverter-duty induction motors, no competitive drive can match the torque and speed performance of the GPD 515 - the world�s most flexible drive
