CanMOST – Freqently Asked Questions

  1. I want to compare the motor I have in my plant with a new motor. In CanMOST's Motor Savings Analysis module, I have selected "Replace Existing" in the upper left corner of the scenario box. There is no "Select" button to choose my existing motor from the databases.
  2. I want to compare the motor I have in my plant with
    a new motor, but I can't find my present motor in the databases. What can I do?

1. I want to compare the motor I have in my plant with a new motor. In CanMOST's Motor Savings Analysis module, I have selected "Replace Existing" in the upper left corner of the scenario box. There is no "Select" button to choose my existing motor from the databases.

Because the motor databases contain only motors that meet energy efficiency levels allowed by Canada's Energy Efficiency Regulations, CanMOST assumes (perhaps incorrectly) that your existing motor pre-dates these Regulations and is not in the databases. Consequently, when in the "Replace Existing" mode, CanMOST will automatically insert a default energy-efficient (standard) motor for the existing motor, and allow you to select motors for the new motor in the right-hand box.

You have three choices:

  1. If your existing motor was installed after 1995 (the year the first regulations were enacted), you can use the "New" rather than "Replace Existing" scenario from the scenario box in the upper left corner. This will allow you to select motors from the databases displayed on both the left and right sides, and CanMOST will calculate the savings based on the two motors you selected.
  2. If your existing motor was installed before 1995 and you know its efficiency, you can override the data in the left-hand "Existing Motor" box in the "Replace Existing" scenario. Since these values are user-editable, CanMOST will calculate the savings using this new data.
  3. If your existing motor was installed before 1995 and you don't know its efficiency, compare the new motor with the generic energy-efficient motor that is the default value. This comparison will give you a lower limit on the amount of money you will save by replacing your present motor.

2. I want to compare the motor I have in my plant with a new motor, but I can't find my present motor in the databases. What can I do?

The database contains only motors that are allowed to be sold in Canada, i.e., motors that have energy efficiency levels that equal or exceed levels allowed under Canada's Energy Efficiency Regulations. Older motors with efficiencies that are below the allowable levels are not in the database. In this case, you have two choices:

  1. If you know the efficiency of your existing motor, you can type it in the "Energy-Efficient Motor" box on the left. CanMOST will calculate the savings using this new data.
  2. If you don't know the efficiency of your existing motor, compare the new motor with the generic energy-efficient motor that is the default value. This comparison will give you a lower limit on the amount of money you will save by replacing your present motor.
