Abstract
In order to improve a machine tool with a motor spindle, including a main motor integrated into a work spindle coaxially with the spindle axis, the main motor, for its part, comprising a rotor and a stator, and with a cooling device for supplying cooling surfaces of the main motor with a gaseous coolant, so that simple and effective cooling of the main motors of the motor spindles is possible, it is proposed that the stator be comprised of stator plates which, for their part, form cooling surfaces, and that the gaseous coolant be conducted directly along the cooling surfaces of the stator plates.
