Eaton Corporation announced the M-Max sensorless vector adjustable frequency drives, the first of their new Max series of adjustable frequency drives. With a compact design, high torque response, and simple handling, Eaton’s new M-Max series offers customers increased system efficiency and product life.With a compact design, high torque response, and simple handling, the microprocessor-based drives come in single- and three-phase models and incorporate standard features that can be programmed to suit applications including conveyor belts, transport drives, packaging machines, pumps and fans.

The M-Max product line uses a 32-bit microprocessor and insulated gate bipolar transistors (IGBTs) that provide quiet motor operation, high motor efficiency and smooth low-speed performance.

"The M-Max series highlights Eaton’s commitment to making products that increase both efficiency and reliability," says Robert Fenton, product line manager for solid-state power control components, Eaton. "Because the M-Max series produces significantly less heat than similar units, it is able to increase efficiency and the life of the product."

The drives use a 32-bit microprocessor and insulated gate bipolar transistors (IGBTs) to provide quiet motor operation, high motor efficiency and smooth low-speed performance. The standard drive includes a digital display and operating and programming keys that provide drive monitoring, diagnosis and adjustment. Separate terminal blocks for control and power wiring are provided for customer connections.

With integrated electromagnetic compatibility (EMC) filters, the M-Max series meets the requirements of both commercial and industrial networks. Additionally, internal filters for compliance with categories C2 (public network) and C3 (industrial network) are provided. In accordance with International Electrotechnical Commission/European Standard (IEC/EN) 61800-3, shield connection options are also included. The ground connection of the internal filter can be interrupted to use the device in IT networks.

Eaton’s M-Max drives include a start-up wizard, condensed parameter list, and a parameter upload and download tool that minimizes set up and diagnostic time. The hardware includes conformal coated boards, 50°C ratings and a temperature controlled fan which makes it rugged and reliable. When mounted on DIN rail or mounting plates, the drive can be installed side by side. Additional features include: RS-485/Modbus as standard, standard proportional-integral (PI) controller, and several fieldbus options.
