Example #3
The motor of Example 1 is running at 7500 rpm with an intermittent operating torque of 2.35
lb-ft.
FIND:
(a) maximum ON time.
(b) required OFF time for an ON time of 4 seconds.
GIVEN: t
OUT
= 2.35 lb-ft.
From performance curve (EB-106-A PC-26927):
T
C
= 1.30 lb-ft. at 7500 rpm
From Specifications CD-27133:
TCTP = 4 min.
Using (EQ-5) and above values:
t
MAX
= 1.7 minutes
t
ON
= 4 seconds
Using (EQ-2) and known values:
t
OFF
= 7.8 sec
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
