Moment of inertia of 3 phase induction motor
WebAs can be see from Eq. (5), the moment of inertia depends on the axis of rotation. It is only constant for a particular rigid body and a particular axis of rotation. Calculating Moment of Inertia Integration can be used to calculate the moment of inertia for many different shapes. Eq. (5) can be rewritten in the following form, WebLoad inertia reflected to the motor armature shaft Jload (lb-in-sec^2) Total inertia=Jm+Jload Jtotal(lb-in-sec^2) Note that the above values are stated for a single winding with dc motors, and are the phase values for a BLDC motor. Brushless dc motors (BLDC) are 3 phase synchronous motors used in a configuration to be treated as dc …
