The second output end P07 of the IO port of the single chip U outputs a high-low level to control the second triode BG2 to be turned on and off, so as to push the second P-channel MOS transistor to be turned on and off, and further control the power supply of one end of the second group of electromagnetic coils Ki (i is 1 and 2 … … 18) to be turned on and off.
The IO port signal output ends PinX (X ═ 1, 2 … … 18) of the single chip microcomputer U are respectively connected with the gates of the N-channel MOS transistors Mi (i ═ 1, 2 … … 18) in a one-to-one correspondence manner, the sources of the N-channel MOS transistors Mi (i ═ 1, 2 … … 18) are grounded, and the drains of the N-channel MOS transistors Mi (i ═ 1, 2 … … 18) are respectively connected with the other ends of the first group of electromagnetic coils Ji (i ═ 1, 2 … … 18) and the second group of electromagnetic coils Ki (i ═ 1, 2 … … 18) in a one-to-one correspondence manner.
