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.

Which motor has a higher starting torque?
A series-wound commutator motor has the best starting torque because the torque is proportional to the square of the current, and the starting current is set by a current-limiting resistor which is switched out as the motor builds up speed.
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 does the degree of DC excitation affect pull-out torque?
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 is torque percent in electrical motor and unit of torque?
In SI, torque is measured in newton metres (N.m). The percentage torque varies according to the design and specifications of a motor.
Is torque wrench a measuring device?
No, it is a device for setting torque.
Disadvantage over switched reluctance motor?
Relatively unprovenNoisyNot-well suited for smooth torque production
What is meant by Reluctance Torque?
Reluctance torque is the torque generated in a reluctance motor due to the tendency of the rotor to align itself with the stator magnetic field. It occurs as a result of the variation in reluctance in the magnetic path between the rotor and stator. This torque is responsible for the motion of the motor and is one of the main torque components in reluctance motor operation.
What is reluctance torque?
torque of synchronous motor with out feild exitation
What kind of motor uses a differential reluctance pole to produce starting torque?
shaded pole
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

Why does my 1999 Mazda Protege Jump when the gear is switched from Park to Drive?
I have been told that is a sign of a problem with your torque converter.
What scientific factors affect the speed of a long board?

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?
Advantage and disadvantage of synchronous reluctance motor?
Advantage: Synchronous reluctance motors are simple in design, cost-effective, and have high efficiency due to the absence of rotor windings and permanent magnets. They offer good performance at high speeds and low to medium power ratings. Disadvantage: Synchronous reluctance motors have lower torque density compared to permanent magnet motors, which can limit their use in high-torque applications. They may also have a limited speed range and require a motor control system to operate efficiently.
Switched to an electric fuel pump on a 350 and put a fuel pump block-off plate over the old location what are the torque specs for the 4 bolts holding the plate?
Not sure of exact torque, would suggest good gasket, or rtv and use locktite on bolts, torque to approx 15 ft lbs.
Will a 305 cam fit in a 350 and if so would it be a good idea and how would it affect the hp and torque?
it will fit. it may affect computer operation. i think power and torque will be down some,maybe not enough to tell
