hello i'm struggeling with the following questions...
Compare the no load speeds of shunt and series connected motors?
compare the starting torque of a shunt and series motors?
can someone help me?

Of course, I can help you with your questions!
To compare the no-load speeds of shunt and series connected motors, we need to understand the characteristics of each motor type.
A shunt motor has a field winding connected in parallel with the armature winding. This configuration allows the motor to maintain a relatively constant speed, regardless of the load. The no-load speed of a shunt motor is typically close to the synchronous speed, which is determined by the frequency of the power supply and the number of poles in the motor.
On the other hand, a series motor has a field winding connected in series with the armature winding. This configuration allows the motor to achieve high torque at low speeds. As a result, the no-load speed of a series motor is typically higher than the synchronous speed.
To compare the starting torque of a shunt and series motor, we need to consider their respective torque-speed characteristics.
A shunt motor, due to its parallel field winding configuration, produces relatively high starting torque. The torque-speed curve of a shunt motor starts at a high torque value and decreases as the speed increases.
In contrast, a series motor, due to its series field winding configuration, produces even higher starting torque compared to a shunt motor. The torque-speed curve of a series motor starts at an even higher torque value and also decreases as the speed increases.
