WebJan 17, 2024 · The moment of inertia (MOI) is one of the most important parameters of a permanent magnet synchronous motor. High-precision identification of the MOI is essential to ensure system performance. This paper explains an MOI identification method based on the frame of an improved model-reference adaptive system (IMRAS). It improved a model … WebThe moment of inertia is a measure of a rotating object’s resistance to rotation. It is dependent on mass and the distribution of its mass about its axis of rotation. The moment of inertia is the reciprocal of mass in Newton’s second law applied for rotation. The moment of inertia is different and specific to each object’s shape and axis.

The moment of inertia about an axis of a body is calculated by summing for every particle in the body, where is the perpendicular distance to the specified axis. To see how moment of inertia arises in the study of the movement of an extended body, it is convenient to consider a rigid assembly of point masses.
