Abstract

Impulse technologies application in cyclic electromagnetic machines demands improvement of thermal design procedures for the short-time mode. When such machines are developed, the thermal design procedures allow optimizing their operation with respect to the given working procedure. New design relations describing electromagnetic drive heating in the short-time mode have been derived from the finite-difference Newton equation solution. It is assumed that the electric drive is a homogeneous body with ideal heat conductivity. The approximate expressions of permissible heating with respect to impact energy depending on the number of operating cycles or impacts and initial temperature exceed over ambient temperature have been obtained. The derived dependences for the cyclic electromagnetic machine short-time mode can be widely used in practice. They will help to optimize electric drive operation with respect to the permissible heating condition when there is no need to use complicated mathematical formulas. A two-coil cyclic electromagnetic machine is considered as an example of using the design procedure for output parameters in the short-time mode.
