Abstract: A motor control method for coupled an electronic vehicle is provided. The motor controller controls a motor and is powered by a battery. The motor control method includes: when a main relay of the motor controller suddenly breaks contact, in a first phase, feeding back a surge current into the battery to suppress the surge current by a diode and a first current limit resistor of a first protecting circuit of the motor controller; and, in a second phase, conducting a discharge switch of a second protecting circuit of the motor controller by a control unit of the motor controller, and releasing the surge current to a reference voltage range by the discharge switch and a second current limit resistor of the second protecting circuit.

Abstract: A motor controller and a cooling method thereof are provided. The motor controller includes: a first power module; a second power module; a first heat sink having first fins; a second heat sink having second fins; a first partition board; a second partition board; a housing disposed at external sides of the first and second partition boards, with a first channel formed between the housing and the first partition board; a conduit connected to a rear end of the first heat sink and extending to an outlet of the housing; a first flow channel; and a second flow channel passing through the first channel and the gaps of the second fins, for second cold air to be introduced, and processed by a heat exchange process performed by the second power module to generate second hot air that is expelled to the outlet of the housing through the second flow channel.
