WebJul 5, 2024 · 4. Compound DC Motors. Compound DC motors, like shunt DC motors, have a separately excited shunt field. Compound DC motors have good starting torque but may experience control problems in variable speed drive applications. Between the 4 types of DC motors, the potential applications are numerous. Each type of DC motor has its strengths … WebShunt Excited. A shunt excited machine is essentially the same as a separately excited machine, ... (In reality, friction will limit the speed, but damage is likely to occur to the motor. If there is zero flux, the armature voltage is zero and the full terminal voltage is applied across the armature resistance, ...

Counter-electromotive force ( counter EMF, CEMF, back EMF ), [1] is the electromotive force (EMF) manifesting as a voltage that opposes the change in current which induced it. CEMF is the EMF caused by electromagnetic induction . Web3. Plugging of dc machine is normally executed by. (a) reversing the field polarity. (b) reversing the armature polarity. (c) reversing both field and armature polarity. (d) connecting the resistance across armature terminals. SHOW ANSWER. 4.
