The invention relates to a flat plated three-phase linear permanent-magnet synchronous motor, belonging to the motor field. The invention overcomes the problems in the prior flat plated three-phase linear permanent-magnet synchronous motor that the designs of a pitch tau t and a polar distance tau p are not easy considerate, the winding end parts are long and mutual cross, the insulation of the windings is complex, and the production cost is high and so on. The flat plated three-phase linear permanent-magnet synchronous motor comprises an armature part and a permanent-magnet excitation part, wherein, these two parts have gas gap therebetween; the armature part is composed of an armature winding and an armature iron core; the permanent excitation part is composed of a permanent-magnet part and a permanent-magnet yoke; the armature iron core pitch tau t and the permanent-magnet polar distance tau p satisfy the following formula as 3ntau t=(3n+-1)tau p, wherein n is a natural number. The invention not only can be used as the linear motor with high performance, but also can be used as the linear generator with high performance, thereby having wide application prospect.

The invention relates to a recombination current driven nine-phase plane motor, a linear-rotating motor and a driver thereof, which belong to the field of motors and motor control. The invention solves the problems that the prior plane motor and the linear-rotating motor have complex structures, low system efficiency, difficult control and the like. The armature coils of the plane motor and the linear-rotating motor are divided into nine groups, each group of the coils are connected in series to form nine phase armature windings which are in star connections, permanent magnets of the motors have array structures, the opposite angles of permanent magnet units are adjacent to each other, parallel with each other, and vertical but not adjacent to each other, and the permanent magnets at the same line or row have same polarities while the permanent magnets at adjacent lines or rows have opposite polarities. The plane motor and the linear-rotating motor have the advantages of small volume, simple insulation between winding phases, large thrust output of unit volume, quick dynamic response, small positioning force and large active cell motion range. The recombination current driven nine-phase plane motor, the linear-rotating motor and the driver are applicable to driving plane two-dimensional movements and linear-rotating two-dimensional movements, and are particularly applicable in the field of precise driving.

A thermally insulated component comprising a structure having a heated interior and an exterior, and a thermal insulating structure for thermally insulating at least a portion of the exterior of the component structure. The thermal insulating structure comprises an aqueous mixture comprising an inorganic binder and inorganic filler particles, and a fabric comprising inorganic fibers. The fabric is impregnated with the aqueous mixture so as to form a pliable binder structure. The pliable binder structure is disposed completely around at least a portion of the component structure. It can be desirable for the component to further comprise at least one thermal insulator comprising inorganic fibers, where the thermal insulator is disposed between the pliable binder structure and the exterior of the component structure.
