Calculate the terminal voltage of Permanent Magnet DC motor having a resistance of 2 Ω and a full load current of 5 A with 20 V back e.m.f.

Calculate the terminal voltage of Permanent Magnet DC motor having a resistance of 2 Ω and a full load current of 5 A with 20 V back e.m.f. Correct Answer 30 V

Permanent Magnet DC motor is a special type of motor in which flux remains constant. The terminal voltage can be calculated using the relation Vt = Eb+IaRa = 20+5×2 = 30 V.
