Embodiment Construction

[0038] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0039] Figure 4 A schematic diagram showing a cross-section of the moving coil motor of the present invention. The moving coil linear motor comprises an open cylindrical housing 1 of ferromagnetic material. Such ferromagnetic materials can be cold rolled steel, vanadium iron cobalt magnetic alloy or 400 series stainless steel. When the second end of the cylindrical housing is closed, the first end is open. The dead end is constructed of a non-ferromagnetic material, such as aluminum, which has good mechanical properties but has a low density. The closed end of the cylindrical housing 1 plays the role of the base end cap of the linear motor. A series of magnetized arc permanent magnets (radial magnetized permanent magnets) 3 are a...

Abstract

The invention relates to a composite double-coil motor with axial and radial magnets, which is an improved double-moving coil motor. A cylindrical shell of the motor is provided with a closed end and an open end. An inner core is arranged in the center of the cylindrical shell. An annular air gap is formed between the inner core and the cylindrical shell. A permanent magnet consists of a ferromagnet core, is arranged along a vertical axis and terminated at a position close to the closed end of the shell, and comprises an axial magnetized permanent magnet with a first magnetized direction. A coil group can move in the annular air gap, is connected to a power supply, and comprises a first coil winding and a second coil winding, and the first and second coil windings are wound in series in opposite directions. The double-moving coil motor adopts different constructions of the axial magnetized permanent magnets, and two magnetic circuits are provided by one or more radial magnets, so the two coil windings of the double-moving coil motor are allowed to more effectively perform magnetic flux cutting motion in the air gap.

Description

technical field [0001] The invention relates to a moving-coil motor, in particular to a composite double-coil motor with axial and radial magnets. Background technique [0002] A moving coil motor is an electromagnetic device that provides linear mechanical motion on a coil based on the interaction of electric and magnetic circuits. Such as figure 1 As shown in FIG. 2 , a conventional type of moving coil motor consists of a cylindrical inner core and an outer shell surrounding the inner core to define an annular space between the two. One ring magnet is mounted on the inner wall of the housing, while the other is mounted on the outer wall of the inner core. This combination provides a single closed magnetic circuit. A circular coil winding is placed in the middle of the air gap. When current is passed through the coil windings, a linear force is generated by the interaction of the current and the magnetic flux density across the air gap. [0003] figure 2 Another conv...
