Abstract
A machine tool with a generator for generating electrical power is disclosed. The generator has a rotor and a stator. A coil and a magnet are arranged on the stator. The rotor is capable of moving relative to the stator and has a first region and a second region. The rotor is configured in such a way that, during a movement of the rotor relative to the stator, a magnetic flux in the coil is changed due to differences between the first and second regions in terms of their magnetic permeability and/or in terms of their geometric configuration, and an electrical voltage is induced.
Claims21
A machine tool, comprising:
- a motor operatively coupled to and configured to move an output drive;
- a generator separate from the motor and configured to generate electrical power, said generator including:
- a stator,
- a rotor coupled to the output drive and configured to move relative to the stator with movement of the output drive,
- a coil arranged on the stator, and
- a magnet arranged on the stator,
- wherein the rotor has at least one first region and at least one second region, and
- wherein the rotor is configured such that, during movement of the rotor relative to the stator, a magnetic flux in the coil changes due to differences between the first and second regions in terms of their magnetic permeability and/or in terms of their geometric configuration, and an electrical voltage is induced.
A machine tool, comprising:
- a motor powered by one of a mains supply and a battery and operatively coupled to and configured to move an output drive,
- a generator configured to generate electrical power separate from the power provided by one of the mains supply and a battery, said generator including a stator, a rotor coupled to the output drive and configured to move relative to the stator, a coil arranged on the stator, and a magnet arranged on the stator;
- and
- a light source electrically connected to the coil such that electrical energy is supplied to the light source during movement of the rotor,
- wherein the rotor has at least one first region and at least one second region, and
- wherein the rotor is configured such that, during movement of the rotor relative to the stator, a magnetic flux in the coil changes due to differences between the first and second regions in terms of their magnetic permeability, and an electrical voltage is induced.
A machine tool, comprising:
- a motor driven by one of a mains supply and a battery,
- a generator configured to generate electrical power separate from the power driving the motor, said generator including a stator, a rotor configured to move relative to the stator, a coil arranged on the stator, and a magnet arranged on the stator;
- and
- a light source electrically connected to the coil such that the generated electrical power is supplied to the light source during movement of the rotor,
- wherein the rotor has at least one first region and at least one second region, and
- wherein the rotor is configured such that, during movement of the rotor relative to the stator, a magnetic flux in the coil changes due to differences between the first and second regions in terms of their geometric configuration, and an electrical voltage is induced in the coil which provides the power generated by the generator.
