A 230 V , 15 hp DC shunt motor has friction and iron loss of 200 W, the armature resistance is 0.3 ohm and shunt field resistance is 115 ohm What is the maximum efficiency of the motor?
Added by Amy C.
Step 1
The power of the motor is given in horsepower (hp), so we need to convert it to watts (W) because the other values are given in watts. We know that 1 hp is approximately 746 W, so: 15 hp = 15 * 746 W = 11,190 W Show more…

A shunt generator has a 50 kW output, 230 V, field current resistance of 55 ohms, and armature resistance of 0.034 ohms. The voltage drop at the brushes is 1.9 V, and friction/iron losses are 1.5 kW. What is the generator efficiency?

A series-connected DC motor has an armature resistance of 0.5 ̩ and field winding resistance of 1.5 ̩. In driving a certain load at 1200 RPM, the current drawn by the motor is 20A from a voltage source of VT = 220V. The rotational loss is 150W. Find the output power, the motor efficiency, and the load (output) motor torque.

1) A shunt generator supplies 195 A at 220 V. Armature resistance is 0.02 ohm, shunt field resistance is 44 ohm. If the iron and friction losses amount to 1600 watt, find (i) emf generated; (ii) copper losses; (iii) b.h.p. of the engine driving the generator. (iv) commercial, mechanical and electrical efficiency. 2) A 250 V, 20 kW shunt motor running at 1500 rpm has a maximum efficiency of 85% when delivering 80% of its rated output. The resistance of the shunt field winding is 125 ohms. Determine the efficiency and speed of the motor when it draws 100 A from the mains
