Abstract
The disclosure discloses a motor driving method, an apparatus, and a system, and relate to the chip field. The solution may include: When a motor control apparatus determines that a motor needs to rotate at a maximum torque, the motor control apparatus controls a driver to output a first current to drive the motor to rotate. The first current is greater than a rated peak current of the driver and is less than or equal to a maximum load current of the driver. This method can resolve a problem that a waste of costs is caused because a through-current capability improved by a redundancy design of a switching transistor of a motor driver cannot be fully utilized for most customers and application scenarios.
