irregularidades de movimento Explanation: Neste contexto: Com rotação uniforme e sem irregularidades de movimento. Cogging refers to shaft rotation occurring in jerks or increments rather than smooth continuous motion. The non-uniform (“jerky”) rotation results from the armature’s propensity to certain discrete angular positions. The interaction of the armature coils entering and leaving magnetic fields, produced by the field coils or permanent magnets, causes speed changes. The armature tends to speed up and slow down as it cuts through the fields during rotation. Cogging is very apparent at low speeds, and determines a motor’s speed range. Cogging torque: a measure of non-uniform velocity (e.g., jerkiness, momentary stalling, slipping). Cogging (Cogging torque) A term used to describe non-uniform angular velocity. Cogging appears as a jerkiness, especially at low speeds. Desbaste? Nesta frase? |
