Abstract

Motor eléctrico con freno electromagnético, que comprende: - un árbol que gira en unos cojinetes solidario de un disco de freno, - un conjunto móvil de frenado solicitado contra el disco de freno por unos medios de retorno elásticos, - un electroimán solidario de una culata apto para generar un campo magnético que permite desplazar el conjunto móvil de frenado contra la acción de los medios de retorno elásticos, siendo la culata fija con respecto a los cojinetes del motor, - una tapa de protección que cubre la culata, - un captador de velocidad del motor que tiene un órgano móvil arrastrado en rotación por el árbol del motor, estando dicho captador de velocidad situado bajo la tapa y el órgano móvil de este captador está acoplado al árbol del motor por medio de por lo menos un órgano de transmisión cuya conductividad térmica es inferior a la del metal que constituye el árbol.Electric motor with electromagnetic brake, which comprises: - a shaft that rotates in bearings in solidarity with a brake disc, - a mobile braking assembly requested against the brake disc by elastic return means, - an electromagnet integral with a cylinder head suitable for generating a magnetic field that allows moving the mobile braking assembly against the action of the elastic return means, the cylinder head being fixed with respect to the motor bearings, - a protective cover covering the cylinder head, - a sensor for speed of the motor having a moving body driven in rotation by the motor shaft, said speed sensor being located under the cover and the moving element of this sensor is coupled to the motor shaft by means of at least one transmission member whose Thermal conductivity is lower than that of the metal that constitutes the tree.
