An insulation monitoring electric circuit of an electric-motor controller, includes: a first voltage sampling circuit and a second voltage sampling circuit; the first voltage sampling circuit is connected to an input anode (+VBUS) of a busbar, an input cathode (PGND) of the busbar and a busbar-voltage sampled-signal (HV_VDC) line, and a busbar-voltage sampled-signal (HV_VDC) line is connected to the electric-motor controller; the second voltage sampling circuit is connected to the input anode (+VBUS) of the busbar, the input cathode (PGND) of the busbar and an insulation-voltage sampled signal (HV_VDC) line, and an insulation-voltage sampled signal (HV_VISO) line is connected to the electric-motor controller; and the electric-motor controller is configured to compare a busbar-voltage value gathered by the first voltage sampling circuit and an insulation-voltage value gathered by the second voltage sampling circuit, and when the busbar-voltage value and the insulation-voltage value are different, emit an insulation monitoring alarming signal.
