WebA DC shunt motor 200V, I,=12A, 1940 rpm has armature resistance (Ra) of 0.5 ohm is working in rated condition. If we reduce the terminal voltage to 150 V, what would be the new speed of the motor if torque does not change and stay the same. Assume a linear magnetization curve for this machine. WebOct 12, 2024 · Let the flux ( φ) of the motor is decreased by decreasing the field current. The decrease in flux will drop the back emf (E b = N φ /K) instantly, causing the armature current to increase because the voltage equation of DC motor is given by I a = (V – E b )/R a. Thus, a small reduction in flux will cause the armature current to increase ... is there school tomorrow 2022 ontario
