    • PURPOSE: A motor for a fire alarm is provided to prevent the corrosion of an inner rotor by preventing harmful gas from being inputted to the motor. CONSTITUTION: A permanent magnet is inserted into a case(110) and includes a cover combining unit. The outer side of the case is coated with powder. A driving shaft(122) is protruded to the front center of the case. A coil is wound around the center of a rotor to rotate in the case. A brush is contacted with one side of the rotor and supplies a current. A rear cover(130) seals the inner space of the case. A finishing plate(150) seals a space of the case to which gas is inputted.
