Consider a Permanent Magnet DC Motor with the following constants (pay attention to units) Kt=0.12 Nm/A, Ke=12 V/ 1000 r.p.m, Armature Resistance = 1.5 ohms, Applied Voltage=10V Find the following: (a) No load speed (b) Stall current and Starting torque (c) Maximum Power (d) Suppose I connect the motor to a load of 0.6N-m. What is the equilibrium speed and current consumed (assuming no friction)?
