Lähtöteho
Lähtöteho, literally “starting power,” is a term used in engineering to describe the power an engine or machine is capable of delivering as it begins to move or start operating from rest. Because power equals torque multiplied by angular velocity, the instantaneous mechanical power at zero speed is zero; therefore lähtöteho typically refers to a transient peak power or the maximum short‑term power available during the initial acceleration under specified conditions, rather than the steady‑state rated power.
Common contexts for the concept include electric motors, generators, and internal combustion engines. In motors, the
Lähtöteho is not a long‑term, sustainable rating. It reflects transient capability under conditions at the moment
