Software calculates electricity usage

BE$T software enables users to easily and accurately calculate an existing motor’s annual electricity usage based on its nominal efficiency compared to the annual electricity usage of Standard-E and Super-E premium efficiency motors. It recommends the best motor for an application, and notes the payback period, in months, for replacing an existing motor.

VFD located near motor

Decentralized Control Technology locates the controller, or variable frequency drive, on or near the drive motor, taking advantage of group motor installation provisions in NEC Article 430, allowing a reduction in the number of branch circuits. Power and bus daisy chaining reduces branch circuit hardware and cabling expenses. Field control wiring is greatly reduced by operating on common bus networks, such as DeviceNet, CANOpen, Profibus, and Interbus.
