Abstract: The electrical machine has a stator, which comprises thirty-six slots and thirty-six teeth with an alternating sequence and a winding system (10) which is arranged at least partially in the slots and has three winding phases (34, 35, 36). The winding system (10) contains in total eighteen coil elements (11-28), which are laid in in each case two slots, with the result that a slot associated with another of the coil elements (11, 12, 16, 17, 18, 22, 23, 24, 28) is located between the two slots associated with one of the coil elements (13, 14, 15, 19, 20, 21, 25, 26, 27). In each case two of the coil elements (11-28) form one of nine interwound groups of coil elements (29), wherein, of the four adjacent slots belonging to a group of coil elements (29), the first and the third slot are associated with one coil element (13, 14, 15, 19, 20, 21, 25, 26, 27), and the second and the fourth slot are associated with the other coil element (11, 12, 16, 17, 18, 22, 23, 24, 28) in this group of coil elements (29). The two coil elements (11-28) of each group of coil elements (29) are associated with in each case two different winding phases (34, 35, 36). In each case one substantially unwound tooth (30) is provided between two adjacent groups of coil elements (29).

Abstract: A drive system includes a rotary drive unit for rotating a shaft and a linear drive unit for moving the shaft in a linear direction. To improve efficiency and shelf life, an energy storage is mechanically connected to the shaft for biasing the shaft to seek a linear movement in opposition to the linear direction. The energy storage absorbs the kinetic energy of the shaft and releases it again subsequently.
