Theoritical torque speed curve for a synchronous machine will be a vertical line located vertical to the synchrounous speed at x axis, from starting torque to stalling torque value. This is because theoritically synchronous motors are not self starting. Practically however they start as induction motors and at near synchrounous speed the excitation is switched on. Anand Sekhar
It is possible using flat belts as they can be wide to provide torque and have great bending characteristics to accommodate the twist.
More current in the field coils means a stronger magnetic field for the armature to rotate in. This causes the output voltage for a generator to increase. For a motor, more magnetic field means that the supply voltage can be matched at a slower armature rotation speed, so the motor runs more slowly but can supply more torque.
In SI, torque is measured in newton metres (N.m). The percentage torque varies according to the design and specifications of a motor.
No, it is a device for setting torque.
The pullout torque is the maximum torque a motor can achieve. Also known as breakdown or peak torque. It occurs at the point where, the increase in the rotor current is exactly balanced by the decrease in the rotor power factor.
as long as your extension is 90 degrees from the handle it will not affect your torque wrench. if you use a super long torque wrench you may lose a little torque in the extension it self but should not affect torque. an extension affecting the wrench in lenght like a crows foot will affect torque as long as your extension is 90 degrees from the handle it will not affect your torque wrench. if you use a super long torque wrench you may lose a little torque in the extension it self but should not affect torque. an extension affecting the wrench in lenght like a crows foot will affect torque
Yes, in synchronous motor theory, excitation current is the same as field current. This current is used to produce the magnetic field in the rotor that interacts with the stator current to generate torque and make the motor operate synchronously.
for torque improvement in armature and create n-pole or s-pole in armature a dc source is used in alternator armature.
30 Nm + 90 degree's + another 90 degree's
20nm +180 degree +180 degree

A torque angle gauge is used mainly on torque to yield fasteners. T.Y. fasteners are 1 time use only. They usually have an initial torque setting and second torque setting and then an angle,(for example 30ft-lbs., 60 ft-lbs. then 90degrees). After the second torqueing you sent the angle gauge to 0 and turn to 90 or what every degree is required.
18 ft lbs + 90 degree + 90 degree
Some common torque questions asked in mechanical engineering interviews include: What is torque and how is it calculated? How does torque affect the performance of a machine or system? Can you explain the difference between static and dynamic torque? How do you determine the torque required to move a specific load? What factors can affect the torque output of a motor or engine? How do you calculate the torque required for a specific application or task? Can you discuss the importance of torque in mechanical design and analysis? How do you measure and test torque in a mechanical system? Can you explain the concept of torque multiplication and its applications? How do you troubleshoot and resolve torque-related issues in a mechanical system?
