Abstract
The utility model discloses an electric motor which has strong universality and can be conveniently mounted, and in particular, the electric motor can be mounted in a narrow, long, peculiar and limited mounting and service space, or the rated power of the motor can be conveniently increased or decreased. The electric motor comprises rotors (1), stators (2) and casings (4), and is characterized in that at least two groups of rotors (1), stators (2) and casings (4) are arranged, and the power output shaft of each rotor (1) is combined with a common rotating shaft (3) for power output. The ratio between the length of the rotating shaft of the motor and the outer diameter of the motor can be multiple times as large as the ordinary motor, so the motor can be suitably mounted in a ''narrow and long mounting and service space'', and in particular, the motor is suitable when the ordinary vehicle is altered into an oil-electricity hybrid vehicle. Compared with the ordinary motor with the same power, the universality and convenience are strong, the rated power can be conveniently increased or decreased, the surface area of the casing is large, so that heat can be more quickly dissipated, and the motor can conveniently use various parts of the corresponding ordinary motor, drives and controllers with low cost.
Description
Technical field
The utility model relates to motor machine, especially installs and uses the motor machine that locus long narrow special limited (for example, being used under the fuel and electric hybrid refitted car chassis) or rated power demanding party just increase and decrease.
Background technology
In the recent period, for with the oily energy-saving and emission-reduction of electricity generation, this paper author is when being adapted as the fuel and electric hybrid bus with the ordinary diesel oil bus, run into the difficult problem of preferred motor, owing to reduce the change to the ordinary diesel oil bus as much as possible in order to reduce cost, this car has harsh requirement to motor: install and use that the locus is long narrow specially limitedly (only to have 1.5 meters * 0.28 approximately under chassis
2The space of rice), corresponding machine shaft length is about 5 with motor external diameter ratio: the above and convenient increase and decrease of rated power 60KW.Because motor in the market has bigger gap than this requirement, so answer the new definite purpose motor of development and design.In order to reduce cost, also require this definite purpose motor to compare with common motor in the market, changing lessly has certain general interchangeability and could apply mechanically many parts and the driver and the controller of corresponding common electric machine!
Summary of the invention
The utility model provides a kind of combination motor that makes things convenient for, and has solved the problems referred to above.It is made up of rotor, stator and casing three parts, rotor, stator and casing have two groups at least, the power output shaft of each rotor has synthesized the public rotating shaft of a power output, and each rotor and casing all connect by the public rotating shaft of bearing and this, and each stator is separately fixed on the casing of this group.The utility model is actually several common motors combination motor of totally one armature spindle, also can abbreviate " coaxial composition motor " as.Such motor, its machine shaft length can be several times as much as common electric machine with motor external diameter ratio, can adapt to above-mentioned " long narrow install and use locus " and the convenient increase and decrease of rated power especially.Relatively use with the power common electric machine, the big heat radiation of casing surface area is very fast, and has reached the requirement of " compare with common motor in the market, change less ", general interchangeability is stronger, can low-cost easily many parts and driver and the controller of applying mechanically corresponding common electric machine.
Description of drawings
The utility model is by providing with next embodiment and accompanying drawing thereof.Shown in Figure 1 is the constructed profile of this embodiment, and Fig. 2 is the scheme of installation of this embodiment under above-mentioned fuel and electric hybrid repacking public transport vehicle chassis, the signal right view that this enforcement illustration among Fig. 2 is Fig. 1.Among each figure, size ratio and the position relation between the parts is near actual.
Embodiment
As shown in Figure 1, present embodiment is made up of rotor (1), stator (2) and casing (4), it is characterized in that: rotor (1), stator (2) and casing (4) have two groups at least, the power of each rotor (1) is defeated. and shaft has synthesized the public rotating shaft (3) of a power output, each rotor (1) and casing (4) all connect with this public rotating shaft (3) by bearing (7), and each stator (2) is separately fixed on the casing (4) of this group.Obviously, if the public rotating shaft of present embodiment (3) length and intensity are increased in advance, group number of its rotor (1), stator (2) and casing (4) (being called for short " sub-motor number ") or thickness just can correspondingly increase, the also corresponding increase of rated power is chosen easy to use significantly.
By shown in Figure 1, the hole (9) of each casing (4) that are connected and fixed is arranged on the casing (4), hole (9) are positioned on the lug (5) of casing (4), the axis of hole (9) and public rotating shaft (3) parallel axes.Like this, the assembled in series that can finish each casing (4) is easily fixed.
As seen from Figure 1, each bearing of present embodiment (7) is a same size, in order to fix each bearing (7), can go up in public rotating shaft (3) and adopt axle ring washer and screw thread.By shown in Figure 1, there is the axle ring washer (10) that is used for fixing each bearing (7) position public rotating shaft (3) termination; There is the screw thread (8) that is used for fixing each bearing (7) position public rotating shaft (3) termination.
By shown in Figure 1, present embodiment is brush motor group (sub-motor is identical brush motor), and commutator (6) is arranged in the casing (4).Certainly, the utility model is brushless electric machine group also, can also be the combined group of brush motor and brushless electric machine, and furtherly, except that internal diameter, the type specification of each sub-motor etc. can be inequality.Obviously, has more convenient general interchangeability.Obviously present embodiment is compared with common motor in the market, and casing (4) surface area significantly increases, and heat radiation is very fast, and motor is not easy overheated; Change less, can be easily low-cost many parts and driver and the controller of applying mechanically corresponding common electric machine.
As seen from Figure 2, when this embodiment was used in common car and is adapted as fuel and electric hybrid car, the hole (9) of each casing (4) can be passed through connecting rod (13), (15), (14) respectively and be connected with bolt with crossbeam (12) with chassis longeron (11), and was easy for installation, fixing reliable, need not change chassis.
Claims (4)
