Abstract: A motor control system and a motor control apparatus are provided. The system includes a drive unit, a backup control unit, and a power unit. The drive unit is electrically connected to the power unit, and is configured to convert a received low-voltage drive signal into a high-voltage drive signal and output the high-voltage drive signal to the power unit. The power unit outputs, according to the high-voltage drive signal, a power supply drive signal provided by a high-voltage battery. The power supply drive signal is configured to drive a motor connected to the power unit to rotate. The backup control unit is electrically connected to the drive unit. The drive unit is configured to output a diagnosis signal indicating a running status of the drive unit to the backup control unit. If the diagnosis signal received by the backup control unit indicates that the drive unit is in a fault state, the backup control unit controls the drive unit to stop working, so that the drive unit stops outputting the high-voltage drive signal to the power unit, to control the motor to stop rotating.
