The utility model type selecting motor technology explanation

It is further described for many motors series connection stepless variable engine that the utility model is designed：From drag cup The advantage of motor：One is energy-efficient.Motor power factor is high, no iron loss, without magnetic damping, and efficiency is greatly improved：

1st, drag cup motor low pressure can start：Small drag cup motor 1V just starts, and 3-5V voltage and currents reach 0.5mA；

2nd, high-low temperature resistant：All can normal work under the low temperature condition of 40 degrees below zero；

3rd, energy conversion efficiency is very high：Its maximal efficiency is general more than 80%, and portioned product can reach more than 95%（Iron core Motor is general in 50-80%）The equal iron core motor ratio of this parameter just can save energy 10% -30%；

4th, control sensitive：Start, braking it is rapid, response is exceedingly fast, and mechanical time constant is less than 28 milliseconds, and portioned product can be with Reach within 10 milliseconds（Iron core motors are general more than 100 milliseconds）Easily rotating speed is sensitively adjusted；

5th, dragging is stable, very reliably, the fluctuation very little of rotating speed, and as micromotor, its fluctuation of speed can be light Easy control is within 2%；

6th, small volume, the energy density of drag cup motor significantly improves, compared with the iron core motors of Same Efficieney, Iron-core-free, its weight, volume mitigate half.80% steel, 100% silicon steel sheet, 50% copper material can be saved；

7th, energy efficiency is improved, in the application with storage battery power supply, hollow-cup motor design can be with extension device Service life is by about one time；

8th, the two type selecting parameter of electric machine is contrasted：

A, efficient core motor, 10KW, 6000 revs/min, specified torsion 16.99Nm outputs, diameter 110MM is long 220MM, the KG of volume weight 10, the 3 motors gross weight after assembly that is together in series maintain an equal level compared with petrol engine weight；

B, efficient switch magnetic group motor, 10KW, 6000 revs/min, specified torsion 31Nm, volume diameter 220MM are long 331MM, volume weight 40KG；

9 but drag cup motor is defective, exactly it is difficult to do bigger power requirements, it is outer straight typically at 10 to 110 millimeters Footpath, power is not big enough, and middle low speed does not have advantage, is presently used only on unmanned plane and Medical Devices, too small to be applied to automobile Deng on large-sized power equipment.

This variable speed box technology solves the problem of high-performance small machine is applied to automobile power, and hollow-cup motor is had Have efficiently, low noise, sensitivity be good, long lifespan, the advantages of small volume, equipped planetary structure series connection case is coupled, and realizes true Many motors series connection stepless variable engine of positive meaning.

The utility model energy saving condition：

1st, 10% -30% energy is saved than iron core motor known to the performance data of hollow motor；

2nd, variable speed box technology such as is coupled with 3 motors, using the most efficient part of many motor overall travel speeds, removes efficiency not High velocity shooting, then 15% -20% energy can be saved；

3rd, motor branch condition, point order, point power, isloation state start and stop use and save 10% or so energy again；

If the 4, also to count the reduction of volume and weight after engine and battery pack diminution in, then save 2% or so energy；

Car external circumstances, are also saved 5% by the 5th, the big data computing of advanced software again with in-car situation together operation control Left and right energy.

Comprehensive this several key technologies can realize made in China automobile as combined domestic Electronic Manufacturing complete sets of Techniques Technology, in the advantage in the whole world, can be social creativity enormous benefits and wide influence power.

Although the utility model is shown and described by reference to preferred embodiment, this area is common Technical staff is it is to be appreciated that the description of the present embodiment can be not limited to, in the range of claims, can make form and thin Various change on section.
