The permanent DC motor model CDP3450 by ABB is rated at 1 Hp, 2
500 RMP at 90v (no load).
The armature resistance is 0.425 Ohm.
a.
The continuous current rating of
this motor is 9.7 Amp, what is
the maximum
continuous torque rating?
b.
The motor is to drive a load of
2NM torque while maintaining a
constant speed of 2000
RPM. What is the required supply
current and voltage?
c.
With 90v armature voltage, what
is the maximum torque at 0 speed (stall torque),
1000rpm, 2000rpm, and 2300rpm?
(Note: Continuous torque rating is less than the maximum torque. For application
where torque is not constant, such as in servo application, mot
or current can be
momentarily driven to much higher
than the continuous current rating.)
