(3) summary of the invention
Poor in order to overcome in the prior art high resistant rate alloy strip resistance conformability, can not satisfy locomotive to requirement, the resistive band of field weakening resistance deficiency easy to crack, the utility model provide a kind of applicability strong, can satisfy the locomotive of all kinds of models to the needs of field weakening resistance, the novel resistance of high resistant rate alloy band that resistive band can not ftracture.
The technical scheme that its technical problem that solves the utility model adopts is:
The novel resistance of a kind of high resistant rate alloy band, comprise resistance alloys band, resistor cartridge, described resistance alloys band is wrapped on the described resistor cartridge, the folding winding of formula in the shape of a spiral of described resistance alloys band, and the individual pen of described resistive band is polygon in the projection of resistor cartridge longitudinal axis.
Further, form bending angle between the adjacent resistor section of described resistive band, described adjacent resistor section is distributed in respectively on the Different Plane vertical with described support longitudinal axis.
