Testing
Complete Test
Complete test consists of the following
items tested in accordance with NEMA
and IEEE-112 test standards.
• Full Load Heat Run
• Temperature Rise at F.L.
• Winding Resistance
• Rated F.L. Slip
• No Load Current
• Breakdown Torque
• Locked Rotor Torque-Amps
• High Potential Tests
• Efficiencies @ 100, 75, 50 Percent Load
• Power Factor @ 100, 75, 50 Percent Load
Test report of complete test is based on
IEEE Std. Form A-2 and includes
complete nameplate information.
Routine Test
Routine test consists of the following items
tested in accordance with IEEE standard 112.
• No Load Current
• No Load Speed
• Locked-Rotor Current
• Winding Resistance
• High Potential
• Bearings/Vibration Check
Vibration data is NOT recorded with a routine
test. If required, please add.
Test report of routine test is based on IEEE
Std. 112 Form A-1 and includes complete
nameplate information.
Calibration Tests
Calibration tests consist of 0-125% rated load test measurement of speed,
torque, current, power factor and efficiency, at rated voltage. Data is curve
rated voltage. Data is curve plotted, on Siemens standard format. Foot
mounted motors only.
Special Tests
For tests or reporting format other than those listed below, contact Siemens
with complete specification, for price additions.
Customers will be notified approximately 2 weeks before witnessed testing.
Refer to Siemens for prices of test reports for adjustable speed drives.
Multispeed motor test reports are priced based upon the number of
speeds tested.
List prices are at the following percentage of the single speed price:
One speed tested 100%
Two speeds tested 150%
Pricing: Five copies of each test report are provided on 8.5” x 11”
paper suitable for reproduction.
Additional copies are available for $55 List per copy.
Vertical Jacking Provisions
This option is provided on foot mounted motors only. It is used to assist the
installer in proper alignment of the motor shaft with the driven piece of
equipment for shimming purposes. Siemens will provide the tapped hole
(one per foot), four per motor. A 1/2-13 UNC threaded hole will be provided
on 280T frame, a 3/4-10 UNC threaded hole on 320T-360T and a 7/8-14
UNF threaded hole on 400T-440T frames. The customer is responsible for
providing the bolts.
