Abstract

The invention provides a water-cooling conductor rotor, a permanent magnet eddy-current speed controller and a permanent magnet eddy-current coupler. The water-cooling conductor rotor comprises a shell (4) and a hollow shaft (3). The shell (4) and the hollow shaft (3) are coaxial, and the shell (4) is fixedly connected with one end of the hollow shaft (3). A cooling water main pipeline (31) is arranged in the hollow shaft (3). A water inlet (32) is formed in the hollow shaft (3). A cooling water branch pipeline (41) is arranged inside the side wall of the shell (4). A plurality of water jetting orifices (42) are sequentially formed in the shell (4) in the radial direction of the conductor rotor. The water inlet (32) is communicated with the water jetting orifices (42) through the cooling water main pipeline (31) and the cooling water branch pipeline (41) in sequence. The permanent magnet eddy-current speed controller with the water-cooling conductor rotor and the permanent magnet eddy-current coupler can jet cooling water to air gaps and the center of a permanent magnet, the whole permanent magnet can be cooled, and the cooling effect is good.

Description

technical field [0001] The invention relates to the technical field of permanent magnet transmission equipment, in particular to a water-cooled conductor rotor, a water-cooled permanent magnet eddy current governor containing the water-cooled conductor rotor, and a water-cooled conductor rotor. Water-cooled permanent magnet eddy current coupler. Background technique [0002] The permanent magnet eddy current governor has gradually been widely used for its safety, reliability, energy saving, environmental protection and other advantages. It uses the basic principle of electromagnetic induction, realizes power transmission through non-contact magnetic coupling, and adjusts the output shaft by changing the electromagnetic air gap. Rotating speed. [0003] The structure of the permanent magnet eddy current governor is mainly composed of three parts: the conductor rotor, the permanent magnet rotor and the controller. The conductor rotor is fixed on the motor shaft, the permanen...
