Abstract

The invention discloses a linear power machine and a power tool. The linear power machine enables the stator component to be installed on the first end and the second end. The mover component is guided and supported by the first end and the second end. No extra guide rail or guide structure is needed to be matched with the mover component. The whole structure is simplified, the size chain of the motor is reduced, the problem that the rotor component and the stator component are damaged by collision due to tolerance is avoided, the requirement for the precision of the components is lowered accordingly, the manufacturing difficulty is lowered, the precision of the motor is improved, and under the condition of the same size, the driving force of the scheme is larger, and the effect is better.Meanwhile, the stator component is partially exposed, heat exchange with external air can be effectively carried out through the exposed area of the stator component to achieve heat dissipation, andthe heat dissipation efficiency is improved.

Description

technical field [0001] The invention relates to the field of motors, in particular to linear power machines and power tools, more specifically to electric-driven tools, especially hand-held electric tools. Background technique [0002] At present, most of the reciprocating motions in the power tool market are realized by rotary motors and conversion mechanisms. There are several problems in this way. low, the cost becomes high. [0003] Linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. Various linear motors commonly used in the market adopt the structure disclosed by the application numbers 201711454263.X and 201820182974.X. This structure has high cost, relatively large size and low power. For power tools with small installation space, especially Cannot be used effectively by hand. Therefore, it is urgently needed for the field of power tools, especially for v...
