The magnitude of electromagnetic or interaction torque, in all rotating machines, is given by ____________
A. Te ∝(stator field strength)sinδ
B. Te ∝(rotor field strength)sinδ
C. Te ∝(stator field strength)(rotor field strength)sinδ
D. Te ∝ sinδ
Answer:A
The magnitude of electromagnetic or interaction torque, in all rotating machines, is given by ____________
A. Te ∝(stator field strength)sinδ B. Te ∝(rotor field strength)sinδ C. Te ∝(stator field strength)(rotor field strength)sinδ D. Te ∝ sinδ
Explanation: The tendency of two fields (stator field and rotor field), to align themselves in the same direction, is called interaction torque, and it also depends on the torque angle & delta;.
