Embodiment Construction
[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0015] Such as Figure 1-4 : 1 is the magnetic ring segment, 2 is the magnetic gap, 3 is the external wire, and 4 is the magnetic sensor.
[0016] The present invention solves the above-mentioned technical problems by adopting the following scheme: the magnetic induction current sensor for the electric vehicle controller of the present invention is composed of a ferrite magnetic ring segment 1 and a magnetic sensor 4 to form a closed magnetic circuit, and the magnetic ring segment 1 is at least There are two, the magnetic sensor 4 is set in the magnetic gap 2 formed between the magnetic ring segments 1 , and the external wire 3 passes through the closed magnetic circuit formed by the magnetic ring segment 1 and the magnetic sensor 4 .
[0017] The technical solution of the present invention may also include: the cross section of the magnetic ri...
