With some motor designs, as the motor starts to accelerate, its torque tends to fall somewhat before starting to increase again. The point of lowest torque in this region of the curve is termed the 'pull-up torque'.

How torque is developed due to alignment of two fields?

Torque is developed by, among other things as well, the magnetic attraction or repulsion of two magnetic fields, contributing through rotational leverage to produce a net torque.


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.


Why is no torque developed by those conductors occupying positions in the interpolar spaces of a motor?

In a motor, conductors positioned in the interpolar spaces do not develop torque because they are situated where the magnetic field is relatively weak and uniform. Since torque is generated by the interaction between the magnetic field and the current-carrying conductors, a lack of significant magnetic flux means that these conductors experience little to no force. Consequently, they do not contribute to the overall torque output of the motor, which relies on conductors located in areas with stronger, varying magnetic fields.


What do you mean by innovation as a science push?

It means that the innovation of the product is lead by "new science" being developed, i.e. new technology leads to the production of a new product, as a pose to market pull innovation, where the market has a need, and science is developed to support the need.


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.

What is pull-out torque formula?

The pull-out torque formula is used to calculate the torque required to pull a fastener out of a material, typically in applications involving screws or bolts. It can be expressed as ( T = F \times d ), where ( T ) is the torque, ( F ) is the force applied to pull the fastener out, and ( d ) is the distance from the center of the fastener to the point of force application (usually the head of the screw). Factors such as material strength, fastener geometry, and surface conditions also influence the effective pull-out torque.


How an energymeter works?

The principle of the energy meter is very simple. i.e., if you place the conduction material between the two magnetic field, that will experience the rotating torque. The torque developed will be proportional to the flux developed. Thus the developed torque will used to run the standard scales.

Why the pull up torque is less than starting torque?

at starting or initial stage there is no acceleration,it requires more force or power to move any body during initial stage,where as in running condition,it also requires some force or power whioch is less then the imitial power.hence the starting torque is always > pull up torque

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.
