A direct current reciprocating thruster

Abstract

The invention relates to a DC reciprocating thruster comprising a magnet group and a movable coil frame. The magnet group comprises an outer and an inner magnet which are concentrically arranged. The outer magnet and the inner magnet have the same cross section in a closed shape. The movable coil frame is arranged axially between the outer magnet and the inner magnet in a sliding way. The two ends of the magnet group are provided with a forward current switch frame and a reverse current switch frame respectively. Linked power swing switches are arranged symmetrically on both ends of the magnet group. Linked position swing switches are installed between the power swing switches and the forward current switch frame or between the power swing switches and the reverse current switch frame. The side surfaces, opposite to the forward current switch frame or the reverse current switch frame, of the position swing switches are provided with corresponding contacts. The DC reciprocating thruster enables the movable coil frame to perform horizontal reciprocating motion by switching current directions by means of an electromagnetic principle, can generate mechanical energy by efficiently utilizing direct current, and solves a technical problem that cannot be solved by a motor.

Description

technical field [0001] The invention relates to the field of direct current motion actuators, in particular to a direct current reciprocating thruster. Background technique [0002] As the main power source now, the motor is widely used. The motor uses alternating current. In many occasions, there is often no alternating current. For example, when directly using a battery to supply power to the motor, a current converter must be used to convert the direct current into alternating current before it can be used. Now There are also DC motors, but the efficiency of DC motors in converting electrical energy into mechanical energy is not high, resulting in relatively large energy waste, so now there is a need for a device that can efficiently convert DC electrical energy into mechanical kinetic energy.
