Adaptable motor ventilator

Abstract

A machine tool comprising a first electric motor, a first shaft, a gear unit, a tool holder, a control device, a power supply, and a rotatably mounted fan. The machine tool includes a drive unit that can be connected to the fan such that the fan can be driven at least at a first and second rotational speed, wherein the drive unit is configured such that the rotational speed of the fan can optionally correspond to a rotational speed of the electric motor, or the rotational speed of the fan can be higher or lower than a rotational speed of the electric motor. A method for controlling and regulating a machine tool comprising a first electric motor, a shaft, a gear unit, a tool holder, a control device, a power supply, a storage unit, and a fan that can be driven by a drive unit.The procedure includes the following steps: - Acquiring at least one temperature value; - Comparing the temperature value with a temperature threshold; and - Adjusting the drive unit from a first to a second speed value when the temperature value corresponds to the temperature threshold.
