The present invention relates to a compact hoist having a high-efficient permanent magnet motor. The compact hoist having a high-efficient permanent magnet motor comprises: a hook which hooks a weight; a wire drum which allows a wire connected to the hook to be wound or unwound thereto/therefrom to vertically move the wire and is rotated around a center shaft used as a rotary shaft core; a hoist embedded motor which provides power for rotating the wire drum in forward and reverse directions and is embedded in the wire drum; and an embedded brake which is embedded in the wire drum and restricts the rotation of the wire drum when a stop signal is inputted. Therefore, the present invention reduces the whole size thereof by applying an embedded hoisting motor and an embedded motor to the hoist and improving the efficiency of the motor. |
