The degree of DC excitation directly influences the pull-out torque of a motor. Higher levels of DC excitation increase the magnetic field strength, resulting in greater torque production and improved performance during load conditions. Conversely, insufficient excitation may lead to reduced torque capacity, causing the motor to struggle under load. Therefore, optimizing DC excitation is crucial for maximizing pull-out torque and ensuring efficient motor operation.

What equivalent circuit element has the most direct control over the speed at which the pullout torque occurs?

The equivalent circuit element that has the most direct control over the speed at which the pullout torque occurs is the inductor. In an electromechanical system, the inductance affects the rate of current change, which in turn influences the torque generated by the motor. A higher inductance can lead to slower changes in current and torque, while lower inductance allows for faster response times and quicker pullout torque. Thus, managing inductance is crucial for optimizing speed and torque characteristics.


What is the effect of a increasing the excitation current?

Increasing the excitation current in an electrical machine, such as a generator or motor, typically raises the magnetic field strength. This can lead to an increase in output voltage for generators or enhance the torque and performance in motors. However, excessive excitation can cause saturation of the magnetic core, leading to diminished returns and potential overheating. Proper management of excitation current is essential for optimal machine performance and longevity.


Drawing of speed-torque curve for synchronous machine?

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


How do you transmit power 90 degree without gears?

It is possible using flat belts as they can be wide to provide torque and have great bending characteristics to accommodate the twist.


How does torque ripple affect switched reluctance motor?

Torque ripple in a switched reluctance motor (SRM) refers to the variation in torque output during operation, which can lead to vibrations, noise, and reduced efficiency. This fluctuation arises from the discrete nature of the magnetic attraction between the rotor and stator poles, resulting in uneven torque production across different rotor positions. High torque ripple can negatively impact the performance and lifespan of the motor, making it less suitable for applications requiring smooth and precise control. Mitigating torque ripple often involves advanced control strategies and optimized design parameters.

Pull-out torque of induction motor?

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.


If you add an exton to your torque wrench does it change the 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 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

In synchronous motor theory is excitation current the same as field current?

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.

How do you use the torque degree gauge add on tool?

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.
