“…It has been shown that exterior Halbach magnetization offers the highest output force within the volume constraints given by the BMW 530i. Equivalent conclusions were drawn for the slotted topology in [22]; however, a higher force density is obtained than in [7]. …”

“…To have an indication of the particular roll forces during high-speed cornering, a test drive with a BMW 530i is performed on the Nürburgring in Germany. The vertical acceleration of the sprung mass is measured, and the resulting roll forces are calculated; an extensive analysis is given in [7]. A time interval of the calculated forces deducted from the measurements, together with the steering angle, is shown in Fig.…”

Abstract-This paper offers motivations for an electromagnetic active suspension system that provides both additional stability and maneuverability by performing active roll and pitch control during cornering and braking, as well as eliminating road irregularities, hence increasing both vehicle and passenger safety and drive comfort. Various technologies are compared with the proposed electromagnetic suspension system that uses a tubular permanent-magnet actuator (TPMA) with a passive spring. Based on on-road measurements and results from the literature, several specifications for the design of an electromagnetic suspension system are derived. The measured on-road movement of the passive suspension system is reproduced by electromagnetic actuation on a quarter car setup, proving the dynamic capabilities of an electromagnetic suspension system.

“…The developed model gives exact magnetic field distribution due to permanent magnets and armature currents with taking into account stator slotting in surface-mounted flat and tubular linear machines. Compared to finite element method, the analytical model is less time consuming and is more convenient to use in a design optimisation process (1) (2) . It is important to note that the proposed model has to be used in the first stage of the design process (pre-design stage).…”

An exact 2D analytical model for predicting the magnetic field in idealized structures of flat and tubular linear permanent magnet machines with surface-mounted magnets and semi-closed slots is described. The open-circuit and armature reaction magnetic field distributions are analytically derived and compared to those obtianed by finite elements analyses. The analytical model is then used for studying the effect of the slot-opening dimensions on the performance of linear machines. The developed analytical model can be advantageously used for the analysis and design of a class of linear machines.
