Computational schemes of ED mechanical part

Elements of ED mechanical part are mechanically linked with each other and make a unique kinematic link from electric motor to actuating mechanism. Every element has its own speed and is characterized by its inertia moment or mass, and also by a set of moments and forces, that act on it. Movement of every this elements can be described by one of the equations (2.3) or (2.4). Interaction of this element with another ones of kinematic link must obligatory be taken into consideration. The most convenient assumption is to be realized through reducing of moments, pulling forces, inertia moments and masses.

As a result of realization of reducing the real kinematic link is replaced with computational energetically equivalent scheme, the basis of which is the element that motion is being considered.

Reducing of such values can be realized for any element of ED mechanical part, but in most cases the electric motor shaft is this element.

The essence if reducing methods will be considered as ED lifting winch. Kinematic link of such device has a view:
