Problems solved by technology

Although the fuselage is light and light, the drilling rate is low and the battery life is low, so it is only suitable for household users. At the same time, the existing rechargeable electric hammer has a lot of noise when the hammer is empty, and the casing is prone to damage. Defects such as oil leakage affect the actual experience of the product

Abstract

The invention discloses a novel brushless motor. The novel brushless motor comprises a rotor mandrel, a rotor punching piece, a rotor spacing sleeve, blades, magnetic steel and a balance ring; the rotor punching piece is tightly connected with the rotor mandrel; the blades are connected with the end, near an output shaft, of the rotor punching piece; the magnetic steel is placed in magnetic steelgroove of the rotor punching piece according to the polarity sequence; the rotor spacing sleeve is arranged on the part, higher than the rotor punching piece, of the magnetic steel; and the balance ring is arranged at one end of an open ring of the rotor punching piece. The novel brushless motor is simple and reasonable in structure, can improve the product positioning precision and save the costin the operating work, and can improve the magnetic steel convenience and the working efficiency.

Description

technical field [0001] The invention relates to the field of electric tools, more specifically, it relates to a novel electric hammer. Background technique [0002] The existing rechargeable electric hammer is basically 12V, and it is a Harvard-style structure. The motor is basically a brush motor, the swing rod bearing is 16.5 degrees, the cylinder diameter is basically 17mm, and the battery pack is basically 3 series single-parallel. Although the fuselage is light and light, the drilling rate is low and the battery life is low, so it is only suitable for household users. At the same time, the existing rechargeable electric hammer has a lot of noise when the hammer is empty, and the casing is prone to damage. Defects such as oil leakage affect the actual experience of the product. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and provides a new type of electric hammer with simple and reasonable structure, significantly incr...
