Abstract

La presente invenzione concerne un motorino elettrico, raffreddato con un flusso d'aria passante attraverso il rotore, comprendente un rotore recante condotti passanti longitudinali e corredato superiormente ed inferiormente di palette radiali che formano rispettivamente due giranti centrifughe, che aspirano aria, l'una al di sopra, l'altra al di sotto del rotore.
