Abstract: Disclosed herein are a motor safety control method that can efficiently detect an abnormality of a motor sensor configured to sense a rotational motion of a motor and control a safety operation of the motor based thereon, and a robot for implementing the method. The motor safety control method for a robot may include receiving a first motor value from a high-resolution sensor of a motor, receiving a second motor value from a low-resolution sensor of the motor, and comparing a threshold with a difference between the first motor value and the second motor value, and transmitting an operation signal to a motor driver for the motor to continue or stop operation of the motor.

Abstract: An inductively electrically excited synchronous machine is disclosed. The synchronous machine includes a rotor including at least one rotor coil for generating a magnetic rotor field, a stator including at least one stator coil for generating a magnetic stator field, a rotary transformer including at least one transformer primary coil fixed to the stator and at least one transformer secondary coil arranged fixed to the rotor for supplying the at least one rotor coil with electrical energy. A machine control is connected to the stator coil and the transformer primary coil. A demagnetisation circuit is electrically interconnected with the stator coil and includes a switching device. The switching device is configured so that during a normal operation the switching device deactivates the demagnetisation circuit and that upon a machine fault the switching device activates the demagnetisation circuit.

Abstract: A method for manufacturing a rotor includes filling magnet housing holes, which accommodate magnets, with plastic that has been heated to a specified temperature to be molten, thereby heating a rotor core with heat of the plastic, arranging an end plate on one end face in the axial direction of the rotor core, thereby heating the end plate with heat of the heated rotor core, and welding the end plate to the rotor core. The welding the end plate includes welding the end plate to the rotor core in a state in which, during decrease of temperatures of the rotor core and the end plate, the temperatures of the rotor core and the end plate are lower than the specified temperature and within an operational temperature range for use of the rotor.

Abstract: Please substitute the new Abstract submitted herewith for the original Abstract: A rotor shaft has a shaft part extending along the axis of rotation of the rotor and which has a rotor body region for arrangement in the rotor body. The shaft part has a carrier element that follows in the axial direction. The shaft part has grooves extending in the axial direction from an attachment region of the shaft part to the carrier element. The rotor shaft includes a slip ring module having a base element with slip rings arranged on the carrier element of the shaft part. The slip ring module electrically conductive module lines extending from the corresponding slip rings inside the corresponding grooves to the attachment region of the shaft part. The rotor shaft also includes a bearing surface, on the shaft part and/or on the slip ring module, for mounting of the rotor shaft.

Abstract: A vibrating plate compactor for compacting earth, soil or substrate, for example on a construction site, wherein the vibrating plate compactor has an electric motor which can be operated in a speed range of more than 12,000 revolutions per minute. A method for operating such a vibrating plate compactor, and to a system including such a vibrating plate compactor and a power tool powered by a rechargeable battery. Both the vibrating plate compactor and the power tool can be supplied with electrical power using the same type of power supply device. Using the invention, different devices on a construction site can be supplied with electrical power more easily, and a vibrating plate compactor with a compact drive unit and small transport size can be provided, in which the compaction result can be improved by an ingenious arrangement of the components and the propulsion can be made faster.

Abstract: An electromagnetic transport system includes a stator and at least one transport unit movable along the stator. The stator includes at least one drive module with an airtight housing where a plurality of drive coils are arranged. A supply cable connects the stator or the at least one drive module to a supply voltage for energizing the drive coils. An empty conduit is integrated into the supply cable and is arranged inside an outer sheath of the supply cable. The empty conduit is provided with an opening at a supply-side end of the supply cable. An end of the supply cable is connected to the at least one drive module such that an exchange of a medium between an interior of the at least one drive module, formed by the airtight housing, and an environment in the area of the supply voltage only takes place via the empty conduit.
