The MV1000 medium voltage AC drive takes a generational leap in ease of application and installation. Designed for energy savings and improved process control, MV1000 drives combine compact modular design, high efficiency, and low harmonics. The MV1000 leads the industry with an MTBF greater than 200,000 hours and an expected drive lifetime greater than 20 years.
Yaskawa Smart Harmonics™ Technology reduces input Total Harmonic Distortion (THD) to less than 2.5% without filters, which exceeds the requirements of IEEE 519 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 high-quality 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, and dedicated low voltage control section. An optional, integrated input switchgear panel is also available with all UL/CSA-recognized components. Indoor MV1000 NEMA 1 Drives are available in 2.4 and 4.16 kV output voltages, with outputs ranging from 200 to 16,000 HP.
Outdoor MV1000 packages are tested to withstand extreme outdoor conditions, from the heat and dust of the arid desert to the bitter cold of the tundra (Standard models: -5°C to +50°C; All Weather models: -45°C to +50°C). MV1000 NEMA 3R Drives are available in an extended range of 500 to 6,000 HP models at 4160 volts.
