DC Electrical Machine: A synchronous motor drives a constant torque mechanical load. Which statement about speed control is true under these conditions? A) The excitation current is directly proportional to the speed. The speed can be adjusted using the excitation rheostat.B) The only method for speed regulation is to change the frequency applied to the motor.C) Sub-nominal speed adjustment is possible with the starting resistor.D) The magnetic flux is inversely proportional to the velocity.E) Under constant torque load, speed can be adjusted by changing the voltage.
A shunt DC motor is supplied by 520V terminals voltage and is used to supply a mechanical load with rotating speed of 1000rpm. The armature is wave-wound and has 500 conductors. The useful flux per pole is 0.03Wb and there are 4 poles (2 pairs of poles). The armature resistance is 0.4 Ohms. Calculate: 1.The internal emf of the motor. 2.The armature current.

QUESTION 19 The torque of a DC motor is at its minimum strength when the motor's armature loop is at the neutral plane O inside of the main field
Can you give me all the different types of DC motor its quite confusing coz some info says it has only 4 which is series , shunt , compount , and permanent magnet which is only under the category of brushed DC motors it doesnt include yet the brushless and the sub category however when you recognize or notice that in flowchart there are several like the one self excited etc I wonder if its an updated version though but I need you to list all of them and explain each and what category or subcategory I mean the overall DC motors even in chatgpt there are some added like universal , stepper , servo , coreless and so on. Explain each one. Pls help me if you could summarize or elaborate all at once so that it would be easy to identify or determine the overall information and additionally per category should have definition as well as the following
