A pump includes a cylinder having a working chamber which contains a fluid. A drive system including at least two linear motors which are connected electrically and/or mechanically in parallel moves a piston in the working chamber to bound the working chamber in the cylinder and to pressurize the fluid in the working chamber. A piston rod is connected to the piston and bundles a force applied by the drive system.

Drive of a pump

A multi-pole component for an electric machine includes an upper side, a lower side, a first magnetic pole having a surface on the upper side, a second magnetic pole having a surface in a tangential direction adjacent to the first magnetic pole on the upper side and a soft-magnetic device. The soft-magnetic device has a recess between the first magnetic pole and the second magnetic pole. A vertical direction is directed from the upper side to the lower side at right angle to a tangential direction. The first magnetic pole has a permanent magnet with a magnetization in one direction, and the second magnetic pole does not have a permanent magnet.
