Motor Data Package
Example #3
The motor of Example 1 is running at 500 rpm with an intermittent operating torque of 64.5 lb-
ft.
FIND:
a) max. ON time
b) required OFF time for an ON time of 4 seconds
(a) Given t
out
= 64.5 lb-ft.
From performance curve EB-606-C
T
C
= 30.6 lb-ft. at 500 rpm
From Specifications CD-27028:
TCTP = 16 min.
Using EQ-5 and above values:
t
MAX
= 4.078 min.
t
ON
= 4 seconds
Using EQ-2 and known values:
t
OFF
= 14.1 seconds
The applications engineers at Kollmorgen can assist in the proper sizing
of the motor and amplifier based on the applications’ duty cycle. Contact
them if any questions arise in the derivation of t
MAX
or t
OFF
with a specific
duty cycle.
