Segmented combined relay type magnetic drive speed reducer and speed reduction method thereof

The invention discloses a segmented combined relay type magnetic drive speed reducer, which comprises a magnetizer and a plurality of coils sequentially arranged in the axial direction. The coils arecoaxially arranged in parallel; the number of coils is not less than three; an initial distance exists between the head of the magnetizer and the tail end of the first coil; in two adjacent coils, thetail end of the former coil is opposite to the starting end of the latter coil, the magnetizer moves in a movement channel in the axis direction of the movement channel, and the length of the magnetizer is larger than or equal to the length of the coil. In application, the magnetizer continuously decelerates by conducting segmented and relay type power-on and power-off on the multiple coils arranged in sequence. By means of the design, the magnetizer can continuously decelerate, the energy conversion efficiency is high, and adjustability is high. 一种分段组合接力式磁驱动减速器，包括一个导磁体以及沿轴向依次排列的多个线圈，各个线圈同轴并列布置，线圈的数量大于等于三，导磁体的头部与第一个线圈
