DC reciprocating motor

Abstract

The invention relates to the technical field of motors, in particular to a motor capable of achieving reciprocating vibration or outputting power outwards through reciprocating motion by being connected with a direct current. The direct current reciprocating motor comprises a casing, an electromagnet pair, a lead, a conversion mechanism, a permanent magnet (30), a buffer mechanism and an output mechanism. The electromagnet pair generates a magnetic field after being electrified, so that the permanent magnet (30) slides between the electromagnet pair; the permanent magnet (30) pushes the conversion mechanism to slide between the electromagnet pair together after sliding for a certain distance, and the sliding of the conversion mechanism can change the direction of the current of the electromagnet pair, so that the magnetic poles of the electromagnet pair are changed, the stress direction of the permanent magnet (30) is changed, and the reciprocating motion of the permanent magnet (30) is realized. The direct-current reciprocating motor is simple in structure and low in cost, and can be applied to various fields, such as electric tools, electric toys, vibration elements, etc.

Description

technical field [0001] The patent of the present invention relates to the technical field of motors, in particular to a motor that can realize reciprocating vibration or output power through linear reciprocating motion when connected to direct current Background technique [0002] The currently used DC motors are all rotated by the rotor installed in them under the action of the magnetic field lines. The traditional DC motors are widely used, have high efficiency and good reliability, but there are still some problems to be solved. [0003] One: The rotor winding of the currently used DC motor is difficult to manufacture, and the production cost is high. [0004] Second: the current DC motors generate vibration by driving the eccentric block to rotate. This kind of vibration is irregular and the vibration is not strong. At the same time, due to the large inertia of the eccentric block, the start and stop of the vibration are very slow, which cannot be done. Very delicate vi...

AI Technical Summary

Problems solved by technology

[0003] One: the rotor windings of the currently used DC motors are relatively difficult to manufacture and the production cost is relatively high

[0004] Second: the current DC motors generate vibration by driving the eccentric block to rotate. This vibration is irregular and the vibration feeling is not strong. At the same time, due to the large inertia of the eccentric block, the start and stop of the vibration are very slow, which cannot be done. Very delicate vibration feedback

Therefore, linear motors in today's mobile phone industry came into being, but the driving current of linear motors requires strong AC characteristics, and generally requires a special driver chip to drive, so the cost is relatively expensive

[0005] Third: the current DC motors need to install additional parts to convert the rotary motion into linear reciprocating motion, such as the common crank linkage mechanism, which increases the volume and energy loss of the entire device in a specific device
