Three-phase power is often unavailable in rural and remote locations, which is a primary reason why farmers struggle to grow their operations. Any farm looking to run larger fans and motors to help increase storage and handling capacity have thus far been forced into using traditional solutions such as rotary phase converters, which are costly, have big capacitor banks and a high amp draw, running up electricity bills and erasing profits. Now, however, increasing numbers are turning to the latest Mitsubishi Electric variable frequency drives (VFDs), which allow a three-phase motor to run from a single-phase electric supply without a phase converter, facilitating greater power and lower energy consumption.
Pursuing its constant innovation approach aimed at making its machines increasingly ergonomic and automated, Cincinnati VR has chosen to equip its new pillar drill-thread cutter with a new integrated variable speed motor, the Commander ID300 from Leroy-Somer. This drive solution enables adaptation of the spindle rotation speed according to the material being worked, for a better-quality machining result.
These new models are the result of several years of research and development. They allow for the first time to produce a power of up to 200 kVA from a LSA 44.3 / TAL 044, while offering genset manufacturers significant gains in efficiency, footprint and transient performances.
