Description

technical field [0001] The invention relates to a transverse flux reciprocating motor and a reciprocating compressor comprising the transverse flux reciprocating motor. Background technique [0002] A motor is a device that obtains rotational or reciprocating force by converting electrical energy into mechanical energy. According to the power applied to the motor, the motor can be classified into an alternating current motor (AC) and a direct current motor (DC). [0003] A motor includes a stator and a mover (or a rotor). The mover provided with the magnet rotates or reciprocates according to the direction of magnetic flux generated when current flows into the coil provided in the stator. [0004] According to the type of motion of the motor, the motor can be divided into a rotary motor and a reciprocating motor. In the case of a rotating electrical machine, the mover rotates relative to the stator by magnetic flux generated in the stator by electric power applied to the ...

AI Technical Summary

Problems solved by technology

If the area of ​​the core is small, the shape of some cores may be distorted and changed during the caulking process, so the size of the core cannot be reduced

Therefore, there is a limit in reducing the size of the motor

[0014] In addition, the above-mentioned conventional reciprocating motor has a problem in that the mover is supported by a mechanical resonance spring of a compressed coil spring, but due to the resonance generated by the compressed coil spring, a specific cycle cannot be used as a driving frequency (even at a certain cycle within the drive frequency)

[0015] In addition, according to the conventional reciprocating motor, when the mechanical resonance spring of the compression coil spring is installed, there are limitations in mechanical stress limit and vibration distance in view of the characteristics of the compression coil spring

So, for example, there is a limit in reducing the horizontal length of a reciprocating motor since the resonant spring should have a certain linear diameter and length

[0016] In addition, according to the conventional reciprocating motor, when the mechanical resonance spring compressing the coil spring is installed, a spring support member for fixing both ends of the compressing coil spring should be provided in each of the mover and the stator, and then there is a problem that makes the motor complex mechanical problems

In addition, since a plurality of resonance springs should be pressurized under high pressure to be installed at the front and rear sides of the mover, there arises a problem that makes the assembly process difficult

[0017] In addition, according to the conventional reciprocating motor, since the mechanical resonance spring of the compression coil spring is installed, and the mover is arranged eccentrically by the lateral force due to the characteristics of the compression coil spring, the friction loss with the stator increases

[0018] Furthermore, according to the conventional reciprocating motor, since the mover including the magnet is set to reciprocate between the outer stator and the inner stator, an air gap is formed on each side of the inner side and the outer side of the mover, thereby increasing the entire air gap, Thus, the problem of deterioration of motor efficiency has arisen

[0019] Meanwhile, according to the conventional reciprocating motor, since the thickness of the magnet frame supporting the magnet is large, and thus the total weight of the mover is increased, power consumption is increased, and the air gap between the outer stator and the inner stator is further increased, As a result, the problem of worsening the efficiency of the motor has arisen

[0020] Finally, the reciprocating compressor using the above-mentioned reciprocating motor still has the above-mentioned problems of the reciprocating motor

Therefore, there are limitations in downsizing reciprocating compressors
