![]() ![]() ![]() Due to the material structure, SMC is isotropic and 3D magnetic flux, compared to electrical steel, lower iron losses at higher frequency(>200HZ).Ībstract Permanent magnet motors with transverse flux structure have been developed for application in direct drive systems featuring high torque at low speed. each of SMC particle is covered with an insulating layer, after pressed by PM technology and heat-treated, low electrical conductivity and thus very low eddy current losses can display. Soft Magnetic Composite (SMC) material is the solution. In machines with three-dimensional flow control, such as transversal or axial flux machines however, this property is highly disadvantages. In electrical machines with 2D flow, such as asynchronous, synchronous and switched reluctance machines, this is fine. Within the sheet plane, electrical steel has a very high magnetic conductivity but a very low magnetic conductivity perpendicular at the same time. there is a bigselection of electrical steel with different properties in all price ranges. ![]() To reduce eddy current losses in the stator or rotor, these are usually designed as a stack of laminations. ![]()
