Q3 (3pkt) Given are the loading torque and rotational speed of electric drive system with synchronous machine controlled by field oriented vector control. Please draw additional waveforms: 1. Electromagnetic torque of the motor (Te) 2. Q component of stator current vector (iq) 3. Mechanical power produced by the motor (Pm) TL Te A TL Pm4 "

The following figure shows the circuit of a DC drive system. Choose the right expression concerning this system. Forward bridge Reverse bridge L1 L1 L2 L3 23 Armature Shunt field L3 23 L2 O a. This drive is a Regenerative DC drive. It allows controlling the motor speed ONLY below its base speed. Changing the rotation direction requires to feed the motor from the reverse bridge. The reverse bridge is also used while braking to transform the excess energy into AC and feed it to grid lines O b. This drive is a Non-regenerative DC drive. It allows controlling the motor speed below and above its base speed. Changing the rotation direction requires external contactors to be connected. The reverse bridge is used while braking to direct the excess energy to braking resistor bank Oc. None of the choices Od. This drive is a Regenerative DC drive. It allows controlling the motor speed below and above its base speed. Changing the rotation direction requires to change the pulses fed into the…

I need help on parts 4 and 5. Also, i am confused on computing the output torque.
