Question: The rated values for a separately excited DC motor are 5.5 kW, 110 V,62A, 1000 r/min. Draw the speed-torque characteristic curve in the steady-state.

The rated values for a separately excited DC motor are 5.5 kW,

The rated values for a separately excited DC motor are 5.5 kW, 110 V,62A, 1000 r/min. Draw the speed-torque characteristic curve in the steady-state. Armature resistance can be estimated by the following : PNUN UNIN IN Ra = (0.5~0.75) 1- %3D | (0,No) (Trated Nrated)
