A brake device includes: a fixed member; a moving member which is movable between a retracted position in which the moving member is adjacent to the fixed member and separate from a braking member, and a braking position in which a friction plate of the moving member contacts the braking member and provides a braking force to the braking member; an elastic member connected between the moving member and the fixed member; a coil disposed in the fixed member; and a controller which provides an operating current to the coil when the elevator is in normal operation, wherein the controller is configured to implement a test mode in which the controller provides a test current less than the operating current to the coil and determines whether the moving member has been attracted to the retracted position.
