ABB (Fort Smith, AR) introduces the third generation of Baldor-Reliance RPM AC motors. Baldor-Reliance Generation 3 RPM AC motors, from 1HP to 1750HP, with customizable speed ranges in nearly any enclosure type, are designed to handle the most demanding applications in industries such as chemical, oil and gas; plastics; HVAC; energy; forest products; metals and industrial automation.
RPM AC motors are optimized for adjustable frequency service - not just a re-rate or over framing of a standard motor. All Baldor-Reliance RPM AC motors are designed to provide continuous constant torque from base speed down to and including zero speed, and - unlike conventional sine wave motors - this means that the RPM AC motor will generate full rated torque, run continuously and not overheat at any speed below base speed. Above base speed, RPM AC produces constant horsepower up to its maximum capabilities.
Gen 3 offers an extended power range, standard grounding provisions, easy setup and deployment and, when combined with optional ABB Ability smart sensor technology, connectivity and data analytics can be accessed by users and technicians onsite or remotely.
Gen 3 also introduces the web-based RPM AC Wizard, a new tool that allows customers to design a motor that best satisfies unique application requirements. Enter horsepower, base speed, top speed and overload requirements, and the Wizard designs a custom motor and full-load current rating that best fulfills the need of the specific application and industry. The wizard also produces complete electrical design curves, performance data and dimension sheets. RPM AC Wizard is a true motor design tool, not just a table look up program.
