%. What are the main types of electrical machines commonly studied in exams? The main types include DC machines (generators and motors), AC machines (synchronous and induction machines), and special-purpose machines like universal motors and stepper motors. What is the significance
in a synchronous motor? Answer: The maximum torque the motor can develop while maintaining synchronism; beyond this, it loses synchronism. Question: How is the power factor of a synchronous motor controlled? Answer: By adjusting the excitation
