Abstract
An electromagnetic active engine mount apparatus includes a sub-channel through which working fluid flows is formed in the central portion of an electromagnetic drive so as to be able to cool heat generated from the coil of a solenoid section of the electromagnetic drive by repetitive operation of a vibrating member. Thus, the electromagnetic active engine mount apparatus can inhibit the heat generated from the coil to thus prevent thermal damage to various components formed of rubber, and provide improvement of its durability, reduction of its size, and simplification of its structure.
