Abstract
A fuse component (36) configured to provide overcurrent protection for an electric motor (20) comprises a spiral (41) of a plurality of coaxial wire loops (44) and an outer insulating sleeve (39) surrounding at least a portion of the spiral (41). The overcurrent threshold of the fuse component (36) may be adjusted by changing the number of loops in the spiral (41) or the cross-section area of the wire in the spiral (41). The fuse component (41) may also function as an inductor (35) and/or connected to a speed adjustable resistor.
