EE07: DC MOTOR STARTING CURRENT, BACK EMF, ARMATURE CURRENT AT SPECIFIC SPEED CALCULATOR

Leave a comment

SOURCE VOLTAGE:V

ARMATURE RESISTANCE:ohm

MOTOR SPEED CONSTANT:V/rpm     If you don’t know, you can find this. You need to divide voltage generated to speed at that voltage.

MOTOR SPEED: rpm


RESULTS

STARTING CURRENT: A

BACK EMF: V

ARMATURE CURRENT RUNNING AT :A
