Refer in Fig. 1, Fig. 4, Fig. 5 and Fig. 7, the present embodiment, the drive mechanism 21 of stator 20 covers more for, in the present embodiment
Three sets are depicted, each set drive mechanism 21 includes three groups of excitation components 22, corresponding each 231 points of the magnetic conduction sheet of three groups of excitation components 22
Wei not A1, B1, C1, A2, B2, C2, A3, B3, C3；The wherein corresponding excitation components 22 of tri- groups of A1, B1, C1 form a set of driving machine
Structure 21, the corresponding excitation components 22 of tri- groups of A2, B2, C2 form a set of drive mechanism 21, the corresponding excitation groups of tri- groups of A3, B3, C3
Part 22 forms a set of drive mechanism 21.Mover 30 is shown in Fig. 7 in movement, each magnetic conduction sheet 231 of three sets of drive mechanisms 21
With the relative position of mover 30.In Fig. 7, when A1 magnetic conduction sheets 231 are just to a magnetic conductive board 31, B1 magnetic conduction sheets 231 are located at (d1+
D2 at)/3, C1 magnetic conduction sheets 231 are located at 2* (d1+d2)/3；Meanwhile, A2 magnetic conduction sheets 231 are just to next magnetic conductive board 31, and A3 is led
Magnetic sheet 231 is just to next one magnetic conductive board 31, and B2 magnetic conduction sheets 231 are at (d1+d2)/3 of next magnetic conductive board 31, and B3 is led
Magnetic sheet 231 is at (d1+d2)/3 of next one magnetic conductive board 31, and C2 magnetic conduction sheets 231 are apart from next magnetic conductive board 31
At 2* (d1+d2)/3, C3 magnetic conduction sheets 231 are at the 2* (d1+d2)/3 of next one magnetic conductive board 31.When each B groups excitation group
When the control coil 24 of part 22 is powered, i.e., when B1 groups, B2 groups, the control coil 24 of B3 groups excitation component 22 are powered, magnetic mover
30 magnetic conductive board 31 moves the distance of (d1+d2)/3；Then each C groups excitation component 22 control coil 24 be powered when, i.e., C1 groups,
C2 groups, the control coil 24 of C3 groups excitation component 22 are powered, the magnetic conductive board 31 of magnetic mover 30 move again (d1+d2)/3 away from
From；When the control coil 24 of each A groups excitation component 22 is powered afterwards, i.e. A1 groups, A2 groups, the control coil of A3 groups excitation component 22
24 are powered, and the magnetic conductive board 31 of magnetic mover 30 moves the distance of (d1+d2)/3 again, so that (A, B, C group are encouraged in a power cycles
Magnetic assembly 22 is powered successively), mover 30 advances the distance of (d1+d2).Then energization SECO is BCABCABCA ..., can be with
Control mover 30 advances；And energization SECO is CBACBACBA ..., then mover 30 can be controlled to retreat, the simple side of control
Just.And when the control coil 24 of each group excitation component 22 is powered every time, mover 30 can advance the distance of (d1+d2)/3, then lead to
The thickness of control magnetic conductive board 31, magnetic isolation plate 32, magnetic conduction sheet 231 and antifreeze plate 232 is crossed, can be accurately controlled for intelligent machine
The displacement and precision of the linear electric motors 100 of free degree control, and without accumulated error.
Make and be wrapped on magnetic conduction sheet 231 referring to Fig. 4, control coil 24 can lead to overetched mode, this mode
The precision of the position of 20 magnetic conduction arm of stator 23 can be ensured, volume is reduced, also relatively good processing radiating.Furthermore it is possible to by each set
The control coil 24 of corresponding excitation component 22 carries out (serial or parallel connection) and linked together in drive component, each to control simultaneously
Cover corresponding excitation component 22 in drive component, specifically such as by A1 groups in Fig. 7, A2 groups, A3 groups excitation component 22 control coil
Larger tandem-in-space or parallel connection between 24 progress serial or parallel connections, the stator magnetic conduction arm of motor, although around each magnetic conduction arm
Coil current it is smaller, but the operating current of motor is larger after the coil connection in series-parallel of magnetic conduction arm, can produce larger magnetic
Field and work torque.Further, it can also place axle sleeve 11 between the magnetic conduction arm 23 of stator 20 to reduce friction and reduction stator
Space between 20 movers 30.It is further possible to place detection mover 30 absolute position between the magnetic conduction arm 23 of stator 20
Device or place quick, temperature sensor of power etc..
Further, this is used in the linear electric motors 100 of intelligent machine free degree control, and permanent magnet can be produced in itself first
Raw stronger magnetic field, and this structure of motor makes that the contact area between stator mover magnetic conduction sheet is big, and magnetic field can be produced
Larger work torque.When stator 20 and the axial location of mover 30 skew very little apart from when, stator 20 be laminated structure make partially
The distance for moving very little generates very big torque accumulation, and the linear electric motors 100 that thus be accordingly used in the control of the intelligent machine free degree are relative
Larger work torque can be produced under the volume of very little in the existing linear electric motors controlled for the intelligent machine free degree,
And three sets of drive mechanisms 21 can work, raising work torque further.And magnetic conduction sheet can process very thin, use
The linear electric motors motion smoothing controlled in the intelligent machine free degree, improves control accuracy.Moreover, coil is made in spacer,
The volume of motor is reduced, the power-mass ratio of motor is improved.
It is possible to further select the light reflectance factor of mover magnetic conduction sheet and insulating trip, motor internal increase detection electricity
The device of machine relative position, so as to measure the relative displacement of stator mover and the direction of motion, reduces whole control system
The volume of system.Because the part for being used for the motion of linear electric motors 100 that the intelligent machine free degree is controlled only has mover 30, mover 30
Quality simple in construction is small, and the movement inertia for being used in the linear electric motors 100 of intelligent machine free degree control is small.Work is more stablized
Reliably.
Further, stator can be in ellipticity or frame-shaped, and mover can also coordinate stator for oval or frame-shaped.
Further, the current driving circuit of motor control coil can add sub-driver circuit, so that motor movement
Smoother, position control is more accurate.
Typically, since intelligent machine requires that small volume, multiaxis multi-joint multiple degrees of freedom, motor imagination speed are fast, held
By load is big and load variations fast, the control accuracy requirement of locus is high.Having inside intelligent machine largely needs straight line to drive
Dynamic joint or the free degree.The driving of the intelligent machine free degree requires that motor has maximum power-mass ratio, moment of torsion inertia
Than, broader smooth speed adjustable range, particularly machine people end effector (paw) should be as small as possible using volume, quality
Motor, when especially requiring quick response, servomotor must have higher reliability, and have larger mistake in short-term
Loading capability.Thus the linear electric motors 100 for being used for the control of the intelligent machine free degree can be applied in various intelligent machines, including
Various bionic mechanicals, Digit Control Machine Tool, automatic production line and can substitute mankind's manual labor or complete difference in functionality dress
Put, for example manipulator, operating robot, service robot etc..
