QUESTION 3 and the lifting speed As the resistance before the motor decreased the motor voltage QUESTION 4 Consider a circuit with a resistor in series with a motor, like observed in Activity 2 of the Week 10 Practical, when the load on the motor increases the voltage across the motor and the current through the motor Under this higher load the lifting speed and the motor torque QUESTION5 If the power supply is set to 5 V and a...
3. A 25-kW, 230-V shunt motor has an armature resistance of 0.064 Ω and a field-circuit resistance of 95 Ω. The motor delivers rated output power at rated voltage when its armature current is 122 A. When the motor is operating at rated voltage, the speed is observed to be 1150 r/min when the machine is loaded such that the armature current is 69.5 A a. Calculate the rated-load speed of this motor In order to protect both the motor...
