摘要： A lifter with electro-permanent magnets is provided. It has an external bearing structure closed at the bottom by a plate, provided with a heat shield, and pole pieces secured under the respective poles and protruding from the bottom plate. Each of the electro-permanent magnets has a reversible magnet arranged on top of one of the poles, of a fixed polarization magnet formed by a plurality of blocks placed along the lateral faces of the pole and of a coil arranged around the reversible magnet to cause the reversal of the polarization of the latter by means of an electrical pulse. An airtight air gap between 1 and 4 mm high is formed between each pole piece and the respective pole through the interposition of a plate of thermal insulation material that resists high temperatures provided at each pole with a rectangular window slightly smaller in size than the pole itself, with the top sides of the pole pieces and/or the bottom sides of the poles being provided with peripheral recesses suitable to act as seats for the positioning of the plate.

摘要： Simplification of a device configuration and control is realized, which enables attraction and release by a magnet without using a battery. A magnet work machine includes a generator motor (8) driven by an engine (7); and an inverter (10) which controls a magnet (6) and the generator motor (8) such that the magnet (6) is energized by electric power from the generator motor (8) to attract metal scraps or the like, and during demagnetization for releasing metal scraps or the like, electric power applied to the magnet (6) is transmitted to the generator motor (8) as regenerative power so as to be consumed. The inverter (10) determines a torque of the generator motor (8) as a motor according to a voltage change of a main circuit based on a detected main circuit voltage so as to suppress the voltage change, and gives the torque as a command.
