An electric motor construction kit for assembling a plurality of electric motors includes at least one module and a plurality of assemblies for constructing the plurality of electric motors. At least one assembly of the plurality of assemblies includes one or more modules of the at least one module. Apart from a cooling system of an electric motor of the plurality of electric motors, each module of the at least one module is constructed from carry-over parts.

Electric motor construction kit and electric motor

An electric motor includes a stator, and a rotor which has a rotor shaft. At least one rotor position magnet is disposed on the rotor shaft, and is configured to provide a magnetic signal that can be evaluated, upon a rotation of the rotor shaft, at least for the purpose of determining a respective rotor position of the rotor. At least one carrier is disposed in a rotationally fixed manner on the rotor shaft, and is connected to the at least one rotor position magnet. The carrier includes at least one opening configured to compensate imbalance of the rotor.

Electric motor having a stator and a rotor

A power tool braking device, in particular a portable power tool braking device, for a portable power tool has at least one magnetic field braking unit. The power tool braking device comprises at least one drive unit which has at least one drive element, on which at least one braking element of the magnetic field braking unit is arranged.

Power tool braking device

The invention is based on a hand power tool having an electric motor () located in a housing (), via which an insertable tool () situated in a tool mount () is capable of being driven in a rotating manner, and having a safety device () with which a characteristic value for an occurrence of uncontrolled blockage of the insertable tool () can be detected via a sensor unit (), and the movement of the housing () can be decelerated. It is proposed that the safety device () is formed at least partially by a motor control unit (), via which the electric motor () can be actively decelerated when an occurrence of uncontrolled blockage of the insertable tool () is detected.
