Embodiments of the present application comprise a multi-motor drive circuit. The multi-motor drive circuit comprises at least three motors and at least three drive bridge arms. The at least three drive bridge arms are connected in parallel, and the at least three drive bridge arms and a direct-current power supply are connected in parallel. Each of the at least three motors comprises at least two power interfaces, and the at least three drive bridge arms have a connection relationship with the at least three motors, wherein the connection relationship satisfies: there is at least one different drive bridge arm between at least two drive bridge arms respectively connected to at least two power interfaces of a motor i and at least two drive bridge arms respectively connected to at least two power interfaces of a motor j, and the motor i and the motor j are any two of the at least three motors. The embodiments of the present application can be applied to intelligent vehicles, connected vehicles, and new energy vehicles, and the volume and cost of a drive unit are reduced.
