Medium voltage AC drive is compact, saves energy
Yaskawa's MV1000 medium voltage ac drive family use a modular, compact design for energy savings and are compatible with the 1000 series low voltage ac drive products.
Yaskawa's MV1000 medium voltage ac drive family are designed for energy savings and improved process control and are compatible with Yaskawa’s 1000 series low voltage ac drive products. Yaskawa’s Smart Harmonics Technology reduces input Total Harmonic Distortion (THD) to less than 2.5% without filters which exceeds the requirements of IEEE519-1992 by almost 50%. This technology also provides galvanic isolation between power input and output.
The MV1000 uses two 5 voltage step bridges per phase to generate a 17-level line-to-line voltage output delivered to the motor. The near sinusoidal waveform results in low THD voltage, low torque ripple, and excellent low speed torque, all motor friendly features, again without the need for output filters.
Several motor control modes are available to fit a wide range of applications: Open Loop Vector for smooth acceleration from low speed without an encoder, closed loop vector for demanding high performance applications, and synchronous motor control for retrofits to existing installations.
The MV1000 also features a compact modular design that facilitates transportation, installation, and maintenance. The design includes a transformer panel, power cell panel, control section, and cooling fans resulting in an MTBF (mean time between failures) greater than 200,000 hours.
These medium voltage drives are further simplified by incorporating the same interfaces as Yaskawa 1000 Series low voltage drives. This includes the same digital operator, parameter structure, a medium voltage version of the Drive Wizard Plus software utility, various communication plug-ins and the same USB copy unit.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
