Electromagnetic decelerator with double impellers

The utility model discloses an electromagnetic decelerator with double impellers. A rotor with double impeller is composed of a left-handed impeller (1), a right-handed impeller (2) which are provided oppositely with the same structure and a shaft sleeve (3); a helical blade (4) provided with ten to sixteen vortices is positioned between a magnetic panel (5) of an impeller disk and a front panel (6) of the impeller disk; the helical blade (4) comprises a long blade (4A) and a short blade (4B) which are arranged in a long and short interphase mode and are arranged at identical distances, wherein the long blade (4A) extends out of a hole of the magnetic panel (5) to be connected with the shaft sleeve (3). The electromagnetic decelerator with double impellers solves the problems of poor air flowability and poor heat radiation property among vanes, high temperature of the impeller during operation, poor brake performance, etc. in the existing decelerator. The utility model has the advantages of simple structure, small temperature rise of the impeller, low operating and coil temperature, favorable brake performance, convenient installation and maintenance, safety, reliability, high durability, etc. The utility model is widely suitable for various automobiles, especially luxury passenger cars and medium-sized automobiles.
