Embodiment
Below in conjunction with specific embodiments and the drawings, the present invention is described further.
Shown in Figure 1, a kind of dynamic rotor Power Regulation variable-torque motor, rotor 2 with spend strong cover 27 concentric to be connected as assembly, be sleeved on the spline 18 of main shaft 20, and left and right displacement that can be axial on main shaft 20, the left side that fan 1 is sleeved on main shaft 20 is located fastening by fanning key 4, the right part cover of main shaft 20 is filled with spacing ring 23, main shaft about 20 two ends, plug-in mounting enters to be embedded among the inner ring of left bearing 3 in shell main body 29 and right bearing 19 respectively, left oil sealing 5 and right oil sealing 22 can prevent the intrusion of dust and the leakage of lubricating grease, the axial width of adjustment spacing ring 23, rotor 2 can be made and spend strong moving to right of cover 27 assembly to be located accurately, Hua Jian overlaps the 27 coaxial heart suits in right part, fastening cover bearing 24, shown in Figure 2, the outer ring suit of cover bearing 24, fastening outer sleeve 30, the axis hole dynamic link of two fork shafts 17 of fork arm 16 upper end and two levels on outer sleeve 30 and axial line position, fork arm 16 back shaft 6 is inserted into the right part of the jut be integrated with shell main body 29, the left part of hydraulic jack 9 is dynamically positioned at the bottom of left side chassis body 29 by cylinder bottom earrings axle 8, piston rod 11 right-hand member of hydraulic jack is screwed in screwed pipe 15, the right part earrings of screwed pipe 15, dynamically be connected by the bottom of lower end axle 7 with fork arm 16, adjustment piston rod 11 is screwed into the degree of depth of screwed pipe 15, the distance of adjustable rotor 2 and the axial displacement on main shaft 20 of spline housing 27 assembly, screwed in place nut 14, piston rod 11 can be made not loosen with the connection of screwed pipe 15, left oil pipe 10, right oil pipe 12 is import and export of hydraulic oil, cover the bottom of 13 spiral-locks at chassis body 29, prevent dust from entering in chassis body 29, key 21 is located at main shaft 20 right part, its function guarantees the reliable output of power, stator 28 winding is connected with the terminal 25 in terminal box 26.
The operation principle of above-mentioned dynamic rotor Power Regulation variable-torque motor is: power supply is received on the terminal 25 in terminal box 26, for dynamic rotor Power Regulation variable-torque motor is powered, if the piston rod 11 of oil cylinder 9 is in the state of retraction hydraulic jack 9, then fork arm 16 pulls rotor 2 and spends strong cover 27 assembly to move to right, spacing ring 23 is close to when spending strong cover 27 right part, rotor 2 is in completely relative position with stator 28, magnetic induction dynamics and magnetic flux density maximum, so the power that exports of dynamic rotor Power Regulation variable-torque motor now and moment of torsion maximum.When needs Power Regulation bending moment, by the proportional velocity regulating valve+PLC+ grating scale system of closed-loop control, the piston rod 11 of hydraulic control oil cylinder 9 moves to right (namely piston rod is by when stretching out in hydraulic jack), rotor 2 with spend strong cover 27 assembly to move to left, rotor 2 staggers gradually with the relative position of stator 28, magnetic induction dynamics and magnetic flux density reduce thereupon, the power that dynamic rotor Power Regulation variable-torque motor exports and moment of torsion decline thereupon, the electric current run also reduces thereupon, when rotor 2 is with when spending strong cover 27 assembly to move to left to be close to the right side to fan 1 to its rotor 2 left side, power and the moment of torsion of this dynamic rotor Power Regulation variable-torque motor output are minimum.When the piston rod 11 of hydraulic control oil cylinder 9 again moves to left (piston rod of oil cylinder is in the state of retraction hydraulic jack), rotor 2 with spend strong cover 27 assembly to move to right, the power that dynamic rotor Power Regulation variable-torque motor exports and moment of torsion increase again, so by hydraulic jack 9, the relative position of random regulation and control rotor 2 and stator 28, the innovation that just can realize motor Power Regulation bending moment rapidly, has exactly been dreamed of most.
Principle of the present invention can be expanded equally, derives, produce: dynamic rotor DC motor, dynamic Rotor Asynchronous Motor, the dynamic various dissimilar dynamic rotor Power Regulation variable-torque motor such as rotor rare-earth permanent magnet synchronous motor and rare earth permanent magnetic brushless motor.
By moving rotor Power Regulation variable-torque motor model inspection, checking to emulation, dynamic rotor electromotor design is feasible, can for the power needing the equipment of Power Regulation bending moment to provide coupling, its suitable application area is wide, particularly electrocar, electric coach adopt the present invention to drive, its economize on electricity property, the feature of environmental protection, cruise-ability, acceleration, safe manoeuvring, compared with the special drive motor of existing electric automobile, have incomparable advantage.
