- PURPOSE:
-
- This data base was designed out of necessity.The information
- contained is used by design electrical engineers and technicians
- almost daily.Use this data base as a tool - not as a replacement
- for the NEC manual!!All information assumes a single motorì
- installation.Consult your NATIONAL ELECTRICAL CODE manual forì
- the details of your particular installation.
-
-
-
- THE INFORMATION CONTAINED:
-
- 1. D.C. MOTORS
- 2. SINGLE PHASE MOTORS
- 3. THREE PHASE INDUCTION MOTORS
- 4. THREE PHASE WOUND ROTOR MOTORS
- 5. THREE PHASE SYNCHRONOUS MOTORS
-
- The above data bases provide information as to full load
- currents, motor over current protection rating, the size or
- guage of the wire required to connect one motor of that
- particular horsepower in a general purpose application, the
- conduit trade size required to house the wire, the NEMA size
- starter recommended,the amperage and the recommended fusing.
-
-
- 6.NEMA DATA
-
- This data base is a listing of the NEMA code letters and their
- related locked rotor KVA per horsepower,maximum rating or
- setting of motor branch circuit protective devices,NEMA size
- starters,Hazardous (classified) locations, and NEMA type
- enclosures for starters.
-
- 7.MOTOR FRAME SIZES
-
- Three phase frame sizes for open and totally enclosed,fan
- cooled motors for general purpose are listed in a data base.
-
-
- 8.THREE PHASE CONDUCTORS AMPACITIES
-
- This data base covers the wire guages #18 to 2000 MCM and
- commonly used types of not more than three conductors in a
- raceway etc.
-
-
-
-
-
-
-
-
-
- 9.SINGLE PHASE CONDUCTOR AMPACITIES
-
- The maximum ampere rating of single phase conductors are
- provided in a data base format.
-
- 10.MAXIMUM CONDUCTORS IN CONDUIT
-
- The maximum conductors recommended inside of a given conduit
- size are listed.
-
- 11.THREE PHASE TRANSFORMERS
-
- This data base contains the full load currents for three
- phase transformers at various line to line voltages.
-
-
- 12.RECOMMENDED COPPER WIRE AND TRANSFORMER SIZES
-
- This data base provides the maximum recommened distances
- between a motor and transformer .
-
- 13.FILE RECOVERY MENU
-
- This is a submenu that provides a utility to recover those
- lost data files.
-
-
-
-
- All of the above data bases contain a note area for those
- reminders that designers like to note.All notes in each data
- base are saved in that data base and become a part of it.

- HOW TO RUN THIS SOFTWARE
-
-
- PLEASE MAKE A BACKUP COPY OF EACH DISK BEFORE PROCEEDING!!!!!!!
-
-
-
- First you must have a hard disk drive with at least 0.5 meg
- left for storage.
- Secondly, you must be using DOS 3.0 or better.
- Third step: Set your hard disk to the root directory.
- Fourth step: Insert the disk marked as #1 into your a: drive.
- Fifth step: At the dos prompt type:
-
- DOS PROMPT> A:INSTALL
-
- The program will create it's own directory for installation.
- Sixth step: Follow the instructions as they appear on theì
- screen.
-
- Seventh step: The first time installation may require that
- you tell the data base what type of monitor
- that you have.You must run "YOURSYS.COM" if
- you are told to do so by your machine -
- IT KNOWS BEST!
-
- Eigth step: After you have finished "Yoursys.Com" type "RUN".
-
-
- WHAT SHOWS UP ON YOUR SCREEN
-
-
- The first screen is the data base menu. Make a selection and
- see what you get! Press the "?" key for help. This will explain
- the selection of functions available and what they do.
-
- If an area is displayed that says "NOTES:", this is your area
- to make entries. To enter a note press "A" for add. To edit a
- note, press "E" for edit--very complicated! It may be necessary
- to use the (+) key to select file #2 to make note entries in
- some cases.
-
- IF you select "D" and delete your note - TOO BAD - it's gone!!
