The motor name for synchronous motors at Baumüller is DS. "DS" refers to the German for three-phase current synchronous motor ("Drehstrom-Synchronmotor"). Functional principle of a three-phase current synchronous motor This is a permanently excited synchronous motor, as the magnets glued onto the rotor generate a permanent magnetic field (north and south poles). If current is applied to windings U, V, and W in the stand (also referred to as the housing), this current generates a magnetic field around the windings. This magnetic field and the permanent magnetic field on the rotor cause an immediate attraction between the north and south poles and a repulsion of like poles. This in turn causes the rotary motion of the motor. As a result of this motor structure, the rotating field frequency of the housing and the rotor always remains the same. This is therefore referred to as a synchronous rotating field frequency and the motor is therefore called a synchronous motor. In contrast, the frequency of the housing and the rotor of an asynchronous motor must never be identical. This is therefore referred to as an asynchronous rotating field frequency and the motor is therefore called an asynchronous motor. Animation of a synchronous motor The animation shows a 3-phase winding system. For better clarity, the sketch shows a simple permanent magnet instead of a rotor. As soon as current flows into the windings, a rotating magnetic field is generated in the motor housing as described above. This also flows through the permanent magnets of the rotor, thereby causing a torque. The rotor executes a rotary motion and follows the rotation of the magnetic field.
