Brushless motor simulation method and device

The invention provides a brushless motor simulation method and device. The method comprises the following steps: receiving instruction parameters of a motor driving control module; generating a Hall signal, a current signal and a rotating speed signal according to the instruction parameters; and the Hall signal, the current signal and the rotating speed signal are respectively sent to the motor driving control module. According to the invention, by arranging the simulation device, the simulation device generates corresponding Hall signals, current signals and rotating speed signals according to instruction parameters and transmits the signals to the motor driving control module, so that the motor driving control module can conveniently adjust the simulation device; therefore, the state of the simulation device is consistent with the state parameter given by the user to the motor driving control module; the simulation device is arranged, any state of the brushless motor can be simulated, damage to an electrode
