Cutler-Hammer® MVX9000 sensorless vector adjustable frequency AC Drives from Eaton’s electrical business are designed to provide adjustable speed control of three-phase motors. These microprocessor-based, sensorless vector drives have standard features that can be programmed to tailor the drive’s performance to suit a wide variety of application requirements. The MVX9000 sensorless vector product line utilizes a 32-bit microprocessor and insulated gate bipolar transistors (IGBTs) which provide quiet motor operation, high motor efficiency and smooth low speed performance. The size and simplicity of the MVX9000 make it ideal for hassle free installation where size is a primary concern. Models rated at 480 volts, three-phase, 50/60 Hz are available in sizes ranging from 1 to 10 hp. Models rated at 240 volts, single- or three-phase, 50/60 Hz are available in sizes ranging from 1/2 to 7-1/2 hp. Models rated at 115 volts, single-phase, 50/60 Hz are available in the 1/4 to 1 hp size range.
The MVX9000 series from Eaton’s Cutler‑Hammer line are sensorless‑vector adjustable frequency drives designed for three‑phase motor speed control. They use a 32‑bit microprocessor and IGBT power devices to deliver quiet operation, high efficiency and smooth low‑speed performance.
