Inside and outside dual brush group of motors of the present invention, said basic motor links to each other with shell through drive sleeve.
Inside and outside dual brush group of motors of the present invention; Said drive sleeve include one be tubular structure branch sleeve, said branch sleeve is provided with louvre, the open end of this branch sleeve is step-like structure; Said branch sleeve is connected on the shell; And openend is towards driving motor, and the bottom centre of branch sleeve is to being outside equipped with power transmission shaft simultaneously, and this power transmission shaft links to each other with the output shaft of basic motor.
Inside and outside dual brush group of motors of the present invention; Said drive sleeve include one be tubular structure branch sleeve, said branch sleeve is provided with louvre, the open end of this branch sleeve is step-like structure; Said branch sleeve is connected on the shell; And openend is towards driving motor, and the bottom centre of branch sleeve has the transmission trepanning simultaneously, and the output shaft of said basic motor inserts in this transmission trepanning and links to each other through flat key structure.
Inside and outside dual brush group of motors of the present invention, said shell is inserted in case through bracing or strutting arrangement.
Inside and outside dual brush group of motors of the present invention, said bracing or strutting arrangement is a permanent magnetic strip, said permanent magnetic strip is arranged in respectively on the inwall of outer wall and case of shell, and the opposite face of the permanent magnetic strip on the inwall of the permanent magnetic strip on the outer wall of shell and case has identical polarity.
Inside and outside dual brush group of motors of the present invention, said bracing or strutting arrangement is the case bearing, said case is contained on the shell through the case bearing holder (housing, cover).
Inside and outside dual brush group of motors of the present invention, said external insulation support and stator external insulation support all are fixed on the external support component, perhaps are fixed on the case.
Be connected with many before and after the inside and outside dual brush group of motors of the present invention, driving motor, the rotor output of previous stage driving motor links to each other with the shell of back one-level driving motor.
Workflow of the present invention is:
The present invention can start basic motor earlier and lock driving motor; After making the housing of driving motor when basic motor and finally load reaching specified maximum speed; Final load just has certain inertia and required torque reduces, release and start driving motor more afterwards, and the rotor of driving motor just begins acting; By the time after the rotor of driving motor reached specified maximum speed, the rotating speed of final load had just reached predetermined value.
Operation principle of the present invention is:
Because the rotor of each motor all has the revolving force of an acting, the mechanical energy of group of motors of the present invention can superpose, to export higher rotating speed and bigger torque.This is because the rotor of basic motor and the turning to of rotor of driving motor are identical; The rotor work of basis motor drives its rotor when the housing of driving motor is rotated and also rotates (during locking); When release and when starting driving motor; This basic motor work also has complementary energy to drive the driving motor rotor behind the reaction force that has offseted the driving motor rotor; The rotor work of this basic motor just is not left in the basket, and the merit that the rotor work of basic motor and driving motor rotor work form stack all is delivered on the final load.According to law of conservation of energy, energy neither can produce without reason, also can not wither away without reason, always from a kind of ability that can be converted into another kind of form of form.The group of motors of this cascade is exactly the mechanical energy that changes into the electric energy of basic motor and driving motor dual (multiple) stack, and dual (multiple) rotating speed and torque are provided.
Its rotating speed is an overlaying relation:
For example, when the slowspeed machine of basic motor employing 1,440 RPM, promptly 24 revolutions per seconds (its torque ratio is bigger); Driving motor uses the middle speed motor of 9,000 RPM, promptly 150 revolutions per seconds (its rotating ratio is higher); After the rotor of basic motor makes final load reach 24 revolutions per seconds of rated speeds, start driving motor and reach 150 revolutions per seconds by its rotating speed; Final output speed is superposed to 174 revolutions per seconds, and promptly 10,440 RPM become the high-speed electric expreess locomotive group.
Its torque also is an overlaying relation:
For example, adopt the common electric machine cascade of 3 1.440RPM, the group of motors of this cascade is equivalent to maximum running frequency and has improved 3 times, and not change of maximum running frequency in fact for single common electric machine.Its rotating speed through the stack can reach 4,320RPM, its torque also be 3 times to single common electric machine.
The present invention is specially adapted to make up with the circular cone motor; Also be applicable to and adopt the motor of disc brake, brake sticking brake to make up; As under the prerequisite that brake apparatus and basic motor and driving motor interlock are set on the final load, be equally applicable to make up with common electric machine.
When selecting motor for load, no longer be confined to only select a high-power motor, but can select several motors of lower-wattage to carry out cascade.If the way that not needing runs up most can adopt frequency control lets the equal low-speed running of group of motors, keep constant speed to guarantee final output.For example during 120 yards of speed limits; Also can start from purpose of energy saving, when not needing high torque (HT), let the part motor shut down.If, can use several high-speed electric expreess locomotive cascades for realizing ultrahigh speed, realize being multiple times than the ultrahigh speed output of single motor, no longer made bottleneck and perplexed.
When practice, can select the driving motor of suitable quantity as required, so that rotating speed and torque reach user's demand.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is owing to adopt a plurality of motor cascades, and the mode that housing and rotor all rotate makes motor obtain higher rotating speed, and than original single high-frequency electric machines, torque is higher, even need not to use speed increaser, decelerator or planetary gear.As cooperate all kinds of batteries, generator or sun-generated electric power to use also to need not booster and just can reach high speed, can also in hypoxemia that engine can't be worked, oxygen-free environment, use; Help to improve the deep space probing car under the oxygen-free environment, the Driving technique of the explorer vehicle (electrodynamic type) under the oxygen-free atmosphere layer; Can be used for improving Electric aircraft, hybrid power aircraft; The screw of the screw of electronic ships, hybrid power ships, electric automobile, hybrid vehicle, electric motorcycle, tricycle, bicycle; The Driving technique of hybrid power motor, light cavalry etc.; The high-speed winding that improves the textile chemical fiber industry is first-class, and the dental drill of improvement instrument industry, percussion drill, cutting machine, abrasive machine etc. improve the toy aircraft of competing for speed, compete for speed toy car and kart, the toy ships etc. of competing for speed already.
Simultaneously; Inside and outside dual brush group of motors of the present invention manufacturing is simple; Can have the rotating speed that compares favourably with single high-end motor after the logical motor cascade of several Daeporis and than the bigger torque of single high-end motor; And the expense of a few Daepori three-way motors is far below the expense of a high-end motor, thereby cheap for manufacturing cost.
