Abstract Based on the research of the principle of commutator motor and the
mechanism causing electromagnetic interference(EMI), its EMI characteristics have
been tested and analyzed. The EMI suppression methods by using different filters are
proposed. By comparing the two filtering methods, the result shows that the designed
filter suppresses EMI more effectively. The conducted emission and radiated emission
of commutator motor with are lower than the limits of GB 4343.1-2009.
