What is cogging torque in permanent magnet motors?

What is a torque-speed curve?
Answer : A **torque-speed curve** is a graph that shows the relationship between the torque (rotational force) and the speed (angular velocity) of a motor. It helps to understand how a motor's output ... have a linear relationship, while **AC motors** might have a different curve depending on their design....

What is the unit of torque?

What is the unit of torque?
Answer : The unit of torque is the **Newton-meter (N·m)**. Here's why: - Torque is a measure of rotational force, and it's calculated as the force applied multiplied by the distance from the pivot ... Newtons (N), torque has the same basic concept, but it's applied in rotation rather than linear motion!...

What is meant by torque formula?
Answer : The **torque formula** refers to the mathematical expression that describes the rotational force applied to an object. Torque is what causes objects to rotate about an axis. The formula for torque is: \ ... both the magnitude of the force and how far from the axis of rotation the force is applied....
