The relationship between the torque(T) and power(P) developed in the DC shunt motor is ___________ (Neglecting all the losses)(a) T ∝ √P(b) T ∝ P^2(c) T ∝ ∛P(d) T ∝ PI got this question during an interview.I need to ask this question from Countercurrent Braking of DC Shunt Motors in section Braking of DC Motors & Induction Motors of Electric Drives |

Answer» CORRECT CHOICE is (d) T ∝ P The explanation is: The torque DEVELOPED in the DC SHUNT motor is the ratio of power developed and angular speed of the motor. T=EbIa÷ωm=P÷ωm. T ∝ P. |
