Demolition robot with control and monitoring function to avoid thermal damage to a motor comprised in the demolition robot

A demolition robot, comprising,

• a cable for energy supply to an electric motor comprised in a demolition robot, wherein said cable is intended to be connected to an electric three-phase network on site,
• a pump that is powered by the electric motor for generating a hydraulic flow to
• each consumer comprised in or connected to the demolition robot, wherein the motor
• is activable with varying thermal load values that depend on current consumer's need for hydraulic power,
• one or a plurality of measurement means,
• a control unit arranged to receive information about the thermal load on the motor from each measurement means, determining one or a plurality of
• different partial thermal damage values that are configured to arise on the motor at different thermal loads on the motor, wherein:
• the control unit is adapted to compare one or a plurality of the partial thermal damage values with a normative partial thermal damage, and via an actuator comprised in the demolition robot adapted to limit the thermal load on the motor to a maximum allowable thermal load value, if one or a plurality of the partial thermal damage values exceed the normative partial thermal damage by a predetermined value.
