Version: 1.0.15
Release Date: March 1, 2007
Release Notes
Metric Unit Measurements: Yes

The MotorMaster+International free online software tool includes many of the capabilities and features of MotorMaster+. However, users can evaluate repair/replacement options on a broader range of motors, including 60 Hz motors tested under the Institute of Electrical and Electronic Engineers(IEEE) standard, and 50 Hz motors manufactured and tested in accordance with International Electrotechnical Commission (IEC) standards. This tool allows users to:

  • Conduct analyses in different currencies
  • Calculate efficiency benefits for utility rate schedules with demand charges based upon monthly kW or kVA readings
  • Edit and modify motor rewind efficiency loss defaults
  • Determine best available or most cost-effective replacement motors
  • Compute annual greenhouse gas emission reductions as a result of selecting a NEMA Premium® efficiency motor
  • Select English, Spanish, or French languages.

Intended Users

MotorMaster+ International is designed for industrial energy coordinators, facility managers and engineers, plant electricians and maintenance staff, procurement personnel, and utility auditors who are interested in improving the energy efficiency of motor systems at industrial facilities.

Inputs

To obtain a list of available general purpose induction motors, the user enters the following information in the Motor Selector module:

  • Desired motor power output (hp or kW)
  • Synchronous speed
  • Enclosure type
  • Operating voltage.

This list is ranked in descending order of full load efficiency. Alternatively, the user can choose to view available special or definite purpose motors.

To quickly determine the annual energy and dollar savings of a NEMA Premium efficiency or EFF1 motor over a lower efficiency motor model, the user enters the following information in the Motor Savings Analysis module:

  • Utility rates
  • Motor ratings
  • Motor load
  • Annual operating hours.

The software tool is designed to examine the "New" motor purchase, "Repair versus Replace", and "Replace Existing" operable motor scenarios.

Outputs

Based on input, MotorMaster+International will provide the following:

  • Expanded list of more than 20,000 60 Hz motors from 14 manufacturers, including NEMA Premium efficiency medium voltage (>600 volt) motors
  • A database of 50 Hz IEC motors from 28 different manufacturers
  • Analysis of new motor purchase, replace operable motors, or repair versus replace failed motor cost-effectiveness
  • Technical data to help optimize drive systems, such as data on motor part-load efficiency and power factor, full-load speed, locked-rotor, breakdown, and full-load torque; and full-load, unloaded, and locked-rotor currents
  • Motor purchasing information, including list prices, warranty periods, catalog and model numbers, and motor weights,
  • Energy and dollar savings, simple payback, cash flows, and after-tax rate of return on investment from using a particular NEMA Premium or EFF1 motor in a new purchase or retrofit application.

Release Notes

Version 1.0.15 includes an option to display only NEMA Premium motors in the Motor Selector screen. This addresses the requirement for federal government agencies to purchase only NEMA Premium motors. An IEC50Hz option limits selections to motors that meet or exceed the CEMEP EFF1-High Efficiency motor standard.
