A direct drive means a gearless mechanical connection between motor and machine. This principle can be realized with revolving and linear motors as well. The gearless design has advantages for the simplification of the system as well as for the dynamic performance of the drive. Last but not least the energy consumption is reduced. The simplification leads(More)

There are more and more demands to reduce jerks in electrical drives. This is derived from the wish to reduce mechanical stresses according to peak-torques. The consideration of the dynamic motion gives equations for way, speed, acceleration and jerk. The last one is the third deviation of way above time. The reduction of jerks demands to change the(More)

The excitation of magnetic bearings can consist of the "basic excitationldquo and of the "control excitationldquo. According to this the magnetic flux is not symmetrical to the zero-point of the magnetization diagram. Therefore calculation of the iron-losses must take into account changed loop of the used B-H curve. And on the other hand the area of the(More)
There is an increasing demand to control electrical drives- with revolving or linear motors as well- with minimized jerk during dynamic operation modes. Jerk is defined by the third deviation of way above time. To avoid- or better to decrease - jerk during acceleration and deceleration periods means a loss of acceleration which must be compensated in that(More)
