4. A 150 kW, 1000V, 25 Hz, three-phase induction motor with a star-connected stator winding has a star-connected rotor winding with effective stator/rotor turns ratio of 3.6. The rotor resistance and rotor leakage inductance are 0.01 and 0.64 mH respectively. The stator winding resistance and stator leakage inductance can be neglected. (a) Calculate the stator current and power factor when starting on normal voltage with the slip-rings short-circuited. (b) Calculate the stator current and power factor at a slip of 0.03. (c) Calculate the external resistors connected in delta that should be connected in the rotor circuit to limit the stator current on starting to 300 A. (d) By what factor does the addition of the external resistors increase the starting torque?

Analog to Digital Converters

The analog-to-digital converter (ADC) allows circuits controlled by microprocessors, Arduinos, Raspberry Pi, and various reasonable digital circuits to be connected to the real world. In the real world, analog signals have a continuous stream of information from a variety of sources and sensors capable of measuring sound, light, temperature, or movement, in addition to the many digital systems that interact with their environment by measuring analog signals from those transducers.
