I thought i would contribute an old Westinghouse Life-Line Motor brochure I came upon in one of our filing cabinets. It has historical value if nothing else. The brochure is dated August 1949, and ironically some of these motors still exist in industry today, I know that because I've actually seen them. Here is much of what is in the brochure:



DIREā‚¬T-CURRENT LIFE-LINE MOTORS-TYPE SK are designed for general service. They are unsurpassed for dependability.


  • HORSEPOWER RANGE-1 to 30
  • FRAMES-203-365
  • WINDING-Series, Shunt or Compound
  • VOLTS-115, 230, 550 or 600
  • TEMPERATURE LIMITS 40 degrees C. Continuous Open - Constant Speed.

The new Life Line motor retains the basic design and construction of earlier SK Motors perfected in years of severe service in mines, mills and general industry.

It has many new and improved features, principle of which is the all-steel construction, resulting in greater strength and compactness.

Ratings built in frames 203 to 365, inclusive, meet all NEMA standardized dimensions and are interchangeable with AC motors built in corresponding frame sizes.





Features: READILY ACCESSIBLE BRUSHES, STURDY BRACKET
CONSTRUCTlON, FORM-WOUND ARMATURE COILS, ONE-PIECE ROLLED STEEL FRAME, EASILY REPLACED FIELD COILS

FULL DATA ON NAME PLATE

The illustration shows the thoroughness with which these motors are identified. Speed characteristics and type of winding are included. Re-ordering of duplicate motor and purchase of renewal parts made easy due to positive identification.



METHODS OF MOUNTING

The Westinghouse Open Type SK motor can be supplied for various special mountings when ordered. There is a price addition for variations in mounting arrangement.

FLANGE MOUNTING-Type "B" Flange and Face Plate Mounting. For such applications as machine tools and pumps where motors are built in as part of the machine.

VERTICAL M0UNTING - Ring Base, for such applications as pumps, agitators, eta. Motor usually supplied with enclosing covers, either solid or perforated.

OTHER MOUNTINGS - Where special conditions make other methods of mountings desirable, consult your nearest Westinghouse Sales Office for helpful assistance.



Recommended Control

This table shows the Westinghouse controls recommended for use with the SK DC motors. it includes the Sentinel breakers, Type DnW De-ion Motor Watchman, De-ion Linestarters, Manual Rheostats, Timestarters, both manual and magnetic starters.

Hello again,

Does anyone have a basic Alarm List for Magnatek Impluse P3 Frequency Drive?

I can't find the Magnatek Impulse manual they supplied with the drive originally...

Thanks!

Hello,
Does anyone know what is a Missing Pulse alarm on a Parker 590 drive?
This drive is a DC590, 590+, 590 Plus, SSD 590, or whichever you prefer.

Specifically, I have a Parker SSD DC590 drive powering a 75 HP DC motor. Motor has been running great until recently I started getting these Missing Pulse alarms. I initially thought it was some type of encoder problem since I am using encoder feedback in this system but according to the manual it has nothing to do with the encoder pulse.

I attempted an Autotune of the Parker drive and it's telling me it failed, but i don't know if I'm on the right track since the motor was working fine in this installation.

These drives are good drives and I have good luck on the other Parker 590 Plus installations I have.

I do have the pdf manual for the DC590 drive, but again, looking for some advice...

What is a missing pulse alarm?
