Original Kurzfassung:
A novel linear-rotary electromagnetic actuator
(LREA) intended for the application in dog clutches as a shifting
actuator is proposed in this paper. The main novelty of the LREA
is the possibility to synchronize the speeds of rotating shafts
without mechanical contact between them, which is not possible
in common clutches of this type. In rotary operation, the speeds
are synchronized magnetically, and a mechanical coupling of the
shafts is achieved in linear operation. The actuator has a very
simple construction comparing with other LREAs. The working
principle and the magnetic flux distribution are described in
detail. A 3D magnetic equivalent circuit (MEC) was built to
calculate the complex three-dimensional magnetic flux and make
stochastic optimization of the geometry possible. A mesh-based
system of equations is developed based on the MEC and the
flux linkage and torque were calculated analytically. Finally, a
3D model of the proposed actuator with the same dimensions is
simulated using 3D finite element analysis (FEA). The analytically
obtained results are very close to the FEA results. The developed
analytical model can be used for the design optimization of the
presented LREA avoiding very large time consumption required
for the optimization with 3D FEA. The results of the optimization
will be presented in a following publication.
