Why ac motors are not used in railways?
Ac motor has a low starting torque so that DC series motor used in railways cause DC motor has high starting torque
Why is the torque speed characteristics of a universal motor on ac source different from the torque speed characterisctic of the same motor on a dc source?
The torque-speed characteristics of a universal motor differ between AC and DC sources primarily due to the effects of reactance and phase differences in AC operation. When powered by AC, the inductance of the motor introduces additional impedance, which can lead to a reduction in torque at higher speeds due to increased reactance. In contrast, when powered by DC, the motor operates without these reactance effects, allowing for a more linear torque-speed curve with higher torque at lower speeds. Consequently, the performance characteristics shift significantly between the two power sources.
Are Malibu low voltage transformers AC or DC?
All transformers are a.c. machines.
Who to increase torque of ac motors?
ac voltage
Why capacitor is use in ac machines?
Capacitors are used in ac machines to assist the field during starting.
What is meant by torque?
Torque is nothing but a Twisting Moment.
What is the force exerted by machines?
torque
What role does torque play in the rotational motion of machines?
Torque is the rotational equivalent of force, responsible for causing an object to rotate around an axis. In machines, torque is pivotal for providing the necessary power to drive the rotational motion of components like shafts, gears, and pulleys. The magnitude of torque determines the acceleration or deceleration of rotational motion in machines.

Applications of ac machines?
All house appliances
What role does torque play in the rotational motion of a machines?
Torque is the force that causes an object to rotate around an axis. In machines, torque is essential for producing rotational motion by transmitting power from the source to the driven component. The amount of torque determines the machine's ability to overcome resistance and perform work efficiently.
The basis of general theory and generalised equation of ac machines?
The general theory of AC machines is based on the principles of electromagnetism, which link magnetic fields and electric currents. The generalized equation for AC machines typically includes components for the electromagnetic field, stator and rotor windings, and mechanical motion. These equations are used to analyze the performance and behavior of various types of AC machines like induction motors and synchronous generators.
