A tyre changing apparatus (1) for demounting and mounting a tyre relative to a respective rim of a vehicle wheel (2) comprises: a frame (10); a chuck (11), connected to the frame (10) to rotate about an axis of rotation (A); a working tool (12), connected to the frame (10) and movable towards and away from the chuck; an electric motor (13), connected to the chuck (11) to impart a rotation speed and a working torque to it; a controller (14), including a power unit (141) configured to supply voltage and current as a function of a drive signal (101); a processing unit (142) configured to generate the drive signal (101) and programmed to derive a control parameter (102) representing the working torque delivered to the electric motor (13) and to apply a torque-limiting function as a function of the control parameter (102). The processing unit (142) is programmed to derive an activation parameter and, as a function of the activation parameter, to switch between an activated configuration, in which the torque-limiting function is enabled, and a deactivated configuration in which the torque-limiting function is disabled.
