The invention belongs to the technical field of linear motors, and provides a DC reciprocating linear motor. The motor comprises a stator, a rotor, an end cover and a rotor guide rod; the stator comprises an inner shell made of a non-magnetic material, a stator winding arranged on the periphery of the inner shell and an outer shell arranged on the periphery of the stator winding. The rotor is arranged in the inner shell in a sliding manner, and the rotor comprises a non-magnetic rotor body and two permanent magnet rotor bodies arranged on the left side and the right side of the non-magnetic rotor body. The non-magnetic rotor body is made of a magnetic conductive material; the two permanent magnet rotor bodies are fixedly connected with the non-magnetic rotor body, the ends, connected withthe non-magnetic rotor body, of the two permanent magnet rotor bodies are the same in magnetism, the two end covers are arranged at the left end and the right end of the stator respectively, rotor guide rod through holes are formed in the mover in the axis direction of the rotor, and the left end and the right end of the rotor guide rod are connected with the end covers. The DC reciprocating linear motor provided by the invention is simple in structure and high in efficiency.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a DC reciprocating linear motor and an integrated application device thereof. Background technique [0002] A reluctance type linear oscillating motor disclosed in Chinese patent CN101136576A, such as Figure 7 As shown, the reluctance linear oscillating motor includes a hollow mover made of non-magnetic material, two electromagnetic coils with outer iron core yokes and a cylinder with an air gap support ring arranged on the periphery of the hollow mover Shape mover. When working, the pulsed direct current with different phases is used to supply power to the two electromagnetic coils in turn through the unipolar drive circuit, so that the working magnetic field generated by them forms a back and forth displacement at both ends of the motor, and the mover relies on the principle of "minimum reluctance". "The generated magnetic resistance pull to achieve linear motion. The disadva...
