How can you torque 70 degrees?
To torque to 70 degrees, tighten the fastener to the specified torque value, then use a torque-angle gauge or a torque wrench with angle indication to measure and turn an additional 70 degrees. This method ensures accurate and precise torque control on critical fasteners.
What is breakaway torque?
Breakaway torque is the amount of torque required to overcome the static friction of a stationary object and set it in motion. It is a measure of the minimum force or torque needed to break something free from its initial position.
What horsepower is 18.5 gross ft pounds of torque?
There isn't a direct conversion between horsepower and torque in foot-pounds. Horsepower is a measure of power, while torque measures rotational force. Horsepower can be calculated using a formula that includes torque and engine speed.
Full load torque of induction motor?
The full load torque of an induction motor is the maximum torque it can produce at its rated speed when operating at full load conditions. This torque is necessary to drive the load at the desired speed under normal operating conditions. It is an important parameter to consider when selecting a motor for a specific application.
Is torque is a scalar or a vector quantity?
Since torque is a force, and as such has a direction, it is a vector.
What is crawling and cogging?
When rotor bars are made to run parallel with stator , the torque rises & falls correspondingly causing more pulsations. This is termed as cogging in other qords magnatic locking. This is reduced by making the rotor bars run at an angle to the stator ie crawling in order to make the torque uniform. Crawling on the other hand signifies running of motor at almost one seventh of the rated speed due to interference of seventh harmonics.
What is cogging and crawling in case of 3 phase induction machines?
CoggingInduction motors have a series of slots in the stator and in the rotor. These slots should not be equal in number because if they are, there is a good chance that the motor will not start at all due to a characteristic known as cogging. The slots will align like a stepper motor. For this reason, there are an unequal number of slots in the rotor and in the stator, but there can still be situations where the slot frequencies coincide with harmonic frequencies and this can cause torque modulations. The slots are skewed to keep an overlap on all slots to reduce this problem.CrawlingAnother characteristic of induction motors, is crawling. There are harmonic fluxes developed in the gap due to the magnetics of the motor. These harmonics create additional torque fields. A common problem is with the seventh harmonic where the seventh harmonic creates a forward rotating torque field at one seventh of the synchronous speed. There will be a maximum torque just below 1/7 Ns and if this is high enough, the net torque can be higher than the torque due to the line frequency where at 1/7 Ns, the slip is high. This can cause the motor to crawl at just below 1/7 synchronous speed. There is another crawl speed at 1/13 Ns.
What is cogging effect?
The cogging effect is the attraction between the magnets and the stator poles when at rest; this attraction and cogging is easily felt when trying to turn an electric motor by hand. A common misconception is that cogging is caused by the copper coils; however, this is not the case. An unequal attraction between the magnets and the stator results in the rotors reluctance to turn. The magnets sit comfortably at rest over a pole, and when the rotor is turned, they must move over an air gap before reaching the next pole. The rotor resists the turning, the magnets attempting to stay bonded to the current poles, until just over halfway through the air gap, where the attraction to the next pole is stronger than that of the previous pole, resulting in a "clunking" or jumping effect at low RPM (such as when trying to turn by hand). This is the cogging effect, resulting in a large torque required to begin rotation.

What is ironless motor?
An ironless motor is a type of electric motor that eliminates the use of iron in its construction, typically by incorporating permanent magnets and specific winding configurations. This design reduces weight, increases efficiency, and minimizes cogging torque, resulting in smoother operation and better performance, especially in applications requiring precise control and high responsiveness. Ironless motors are commonly used in robotics, aerospace, and high-performance automotive applications.
What is the torque on a torque converter?
Torque output of the engine at that speed.
What is the difference between electromagnetic torque and load torque in electrical machines?
Electromagnetic torque and load torque are different.Electromagnetic torque is the torque that is produced inside the machine which makes the machine rotate,while load torque is the torque that is applied externally with brake drum and and spring balance.Electromagnetic torque can be varied by varying the speed of the machine,but load torque is fixed.

What is the setting for the torque on 96 31 L Achieva?
The first thing we have to know is--what torque? Is it Head bolt torque, rod bolt torque, main cap torque, water bolt torque, or something else? Please specify.
What is a torque meter?
A torque sensor, or torque meter, is a device that measures the torque on rotating systems, usually wheels. Torque, in this case, is the twisting force that causes rotation, such as that applied when you pedal a bicycle.
