Introduction
 API 541 5th Edition
 Form wound, cage induction motors
 Induction generators too
 375kW (500HP) and larger
 Horizontal or vertical
 ANSI/IEEE/NEMA or IEC/ISO
 Metric units (with US customary)
 General industry not just API

Timing/Process of Revision
 Working group assembled April 2008
 End users, Consultants . . . and motor OEMs
 Open discussions on suggested improvements
 Incorporate API 546 revisions as appropriate
 Sub-groups to discuss/recommend broader changes
 Ballot (second) approval May 2011
 Print proof reviewed in July 2012
 Published December 2014

Why Use API 541?
 Standard specification that provides customized product




Simplifies machine definition
Simplifies proposal preparation
Simplifies proposal evaluation
Provides for a reliable machine
 Utilizes comprehensive data sheets
 Important to everyone involved from manufacturer to user

Service Factor
 Motors shall have a service factor of 1.0
 If overload capacity is required, a higher nominal motor rating shall be selected
 Avoids operating motors above rated power, which increases winding temperatures and
shortens motor life

Service Factor
 NEMA MG1

80
Percentage of life (%)
 Allows 10°C increase in temperature rise when
operating at 1.15SF
 Regardless of voltage, HP, insulation class or
measurement method
 Rule of thumb
 10°C increase ≈ ½ insulation life

Thermal Capacity Data
 Supplier now required to provide thermal capacity data, including:
 Thermal limit curves
 Acceleration curves
 Required stop/running cool times after max starts
 Useful for programming motor protection relays
Unrestricted © Siemens 2016
Page 10
Revised
Thermal Capacity Data
 Thermal limit curves
 Comply with IEEE Std 620-1996 (R2008)
 Ambient and rated running temperature
Running overload
Accelerating
Locked rotor
Time-current
Unrestricted © Siemens 2016
Page 11
Revised
Insulation Temperature Limits
 RTDs measure “hot spot” temperature
 RTDs inserted between coils in the slots
 Average temperature determined by change
of winding resistance
 Permitted hot spot rises are 0 to 10°C above
average rises
Unrestricted © Siemens 2016
Page 12
 Occasionally average exceeds hot spot
meaning hot spot is not the worst case
 Now required to meet the limits by both
methods
 Ensures temperature limits are met
throughout windings
New
Magnetic Stator Slot Wedges
 Not previously been addressed
 Used by many vendors and can improve
performance but some have durability issues
 Requirements –
 Rigid and VPI’d in place, amorphous or
composite construction, 10 year track record,
630 mm shaft height limitation
Unrestricted © Siemens 2016
Page 13
New
Totally Enclosed ≥ 6kV
 For example TEAAC or TEWAC
 Default requirement
TEAAC/CACA
 Free to specify open enclosure if good
experience at site
 Minimizes airborne contaminants
 Reduced risk of electrical tracking
 Reduced risk of early winding failure
TEWAC/CACW
Unrestricted © Siemens 2016
Page 14
Revised
Torsional Stress Evaluation
 Torsional oscillations don’t just break shafts
and couplings!
 Now specify fatigue analysis of fans and rotor
bar overhangs for applications involving
torsional oscillations
 Require infinite fatigue life
 Analyze applied stresses, resonances,
metallurgy and stress concentration
Unrestricted © Siemens 2016
Page 15
Revised
Surge Capacitors
 Surge capacitors reduce the steepness of
surges at the terminals
 Reduce stresses between turns of coils
 Now call for three single phase capacitors
instead of a single three phase unit
 Reduce consequent damage from a capacitor
failure
CTs
Surge

Revised
AC Hi-Potential Testing






AC ‘hipot’ is a standard test before shipping
Voltage = (2 x rated voltage) + 1kV AC
There is no pass/fail criterion defined in other standards
Now require document leakage current, temperature and humidity
Observe end windings for arcing
No rapid voltage/current fluctuations
Unrestricted © Siemens 2016
Page 17
New
Frame Vibrations
 There are cases where shaft vibrations are
within limits but frame vibrations are
excessive
 Often magnetically induced, with a structural
resonance
 Limit ≤ 2 x allowable bearing housing velocity
for structural member at center line height
Unrestricted © Siemens 2016
Page 18
Revised
Unbalanced Response Test
 Unbalanced coast down from 120% speed
 Mass moment simulator included during testing (option before)
 Vibration levels reduced, e.g.  3600rpm: 2.25mils from 2.74mils
 1800rpm: 2.25mils from 3.87mils
 First critical speed must match predicted results (within 5%)
 If not, correct model
Unrestricted © Siemens 2016
Page 19
Revised
Stator Core Test
 Minimum 30 mins with infrared camera
 Below 5°C change from “adjacent” point
 Packs of laminations and teeth next to each
other or
 Within 6cm (2.2”) when no radial ducts
1
 Record (for comparison purposes) of
 Rated flux
 Watts loss/kg of ‘back iron’

2, Radial vent

Revised
Sample Coil Tests
 Optional tests to verify coil integrity and VPI
process
 Two extra coils VPI’d with stator
 Impulse test
 Ground wall
 5 PU, 1.2 µs
 Turn-to-turn
 2.0 & 3.5 PU 0.1 to 0.2 µs
 Then test to destruction
 Cut coils (3 segments) and examine
Unrestricted © Siemens 2016
Page 21
New
Sample Coil Tests PD
 Concerns about imperfect process causing ‘harmful’ insulation voids
 Partial discharge test on the sample coils that have gone through the VPI process, before surge
tests
 For coils with semi-conductive coating in slot section, energize at rated line-to-neutral voltage
with grounded slot
 Suggested 100 pC PD limit
Unrestricted © Siemens 2016
Page 22
New
TEWAC Heat Exchanger
 Some TEWAC heat exchangers have not performed adequately in the field
 Performance was not required to be verified during factory testing
 Inability to fully load machine at the factory
 Added optional factory test, possibly during factory heat-run
 Verify flow and temperatures per specification
Unrestricted © Siemens 2016
Page 23
New
Stator Coil Data
 Having coil data speeds up rewind as coils can
be ordered before motor gets to shop
 Owner should keep coil data sheet
 Uses the standard coil drawing that coil shops
know
 Can order complete set of coils before motor
arrives
 Gets motor back sooner
