Since the excitation coils of electromagnetic-levitation bearing system for the axial load of hydraulic turbine-generator are sealed inside of the system,the heat inside is difficult to be dissipated,and then over-high temperature rise would occur therein.For solving this problem,it is put forward that a few vents are respectively arranged on both the electromagnet core and the armature(thrust disc) of the system,so as to create a convection heat dissipation on the surface of coils.So far as… CONTINUE READING
