A Dc Motor Is Powered With Ea 400v The Armature Resistance Is Ra 20 The Torque Constant Of The Motor Is K 1 Nm 2 (11.63 KiB) Viewed 26 times
A DC motor is powered with Ea = 400V, the armature resistance is Ra = 20, the torque constant of the motor is K+ = 1 Nm/A.
What gear ratio G is required to drive this load at its maximum operating speed? Hint: The load torque intercepts the motor torque in two places, only one will be positive, dwop you will again need to solve = 0. dG
