Some Introduction of Linear motor magnet
Early linear motion driving is achieved by the transformation from rotation to linear motion, by contrast, linear motor driving system has many advantages including high efficiency, control accuracy, dynamic performance, simple structure and also easy to maintain. Linear motor possess relatively higher power density and free of end winding, thus endow distinct technology advantage and promotion value in industrial automation, mechanical and military applications. As an essential component, linear motor magnets have also got a lot of attention.
linear motor can be classified to radial magnetized type, axial magnetized type and halbach type according to the internal magnet array pattern.
About Linear Motor Magnets
Halbach array in linear motor is made of radially oriented magnets and axial magnetized magnets which arranged in a certain order, then obtain much stronger sinusoidal distributed magnetic field on the working side and keeping the field to a very low value on the other side. Actually, halbach array has broad prospects in linear motor, and there is no doubt that both technical difficulty and cost of radially oriented magnets are significantly higher than regular axial magnetized magnets, therefore, the vast majority of linear motor manufacturers are all adopts axial magnetized magnet array in their products. For large-sized linear motor, Hongyu can make radially magnetized magnet by several pieces of diametrically magnetized arc magnet, in the meanwhile, fabricate ultra-small radially oriented linear motor magnets by hot-pressed and hot-pressed process to meet the requirement of motor鈥檚 miniaturization.Motor Magnet Free Sample
