Abstract
The invention relates to a parallel multi-winding motor, which comprises a stator and a rotor, wherein the stator and the rotor are arranged in a casing. The parallel multi-winding motor is characterized in that a plurality of sets of functional windings are wound on the stator in parallel. When all sets of functional windings are connected with an external driver or an alternating current power supply, all the functional windings independently enable the motor to run normally. When a motor structure system is operated, if one set of the windings breaks down, the other windings can maintain normal operation of the system under the condition that the fault winding is not involved in, thereby greatly improving reliability and continuous operation ability of the system. When the parallel multi-winding motor is applied to a high-power motor, a system driving mechanism is simplified, and reliability is improved greatly.
Description
Technical field
The invention belongs to the motor application technical field, relate to a kind of parallel multiwinding machine.
Background technology
Conventional motors; Particularly, heavy-duty motor; Important composition as drive system; Two kinds of system's constituted modes are arranged in practical application, and a kind of is to adopt the direct drive motors of single big capacity driver, and another kind is to adopt a plurality of low capacity driver parallel drive motors (multichannel low capacity driver bank is combined into a big capacity driver and this method belongs to same type).First kind of mode, driver can directly be connected with motor, and is simple in structure; But because conventional motors is single cover winding construction; Big capacity driver and conventional motors are under the complicated applications environment, and both reliabilities all have reduction in various degree, in system's running winding or driver any one go wrong; Then systemic breakdown can occur, can not work fully.The second way, each low capacity driver need be connected with motor through reactance network, complex structure, reliability is not high under the complicated applications environment, and particularly motor is as going wrong, just system can not work fully.In sum, the drive system that is made up of conventional motors is under complicated applications environment, specific (special) requirements applied environment, or reliability is not high, or system can not work fully.
Summary of the invention
The objective of the invention is to solve the problem that prior art exists, a kind of rational in infrastructure, reliability is high, response is fast, the continuous service ability is strong parallel multiwinding machine is provided.
For realizing that the technical solution that the foregoing invention purpose adopts is such: the parallel multiwinding machine that is provided comprises stator and the rotor that is arranged in the casing; It is characterized in that cover function windings more than parallel being arranged with on stator; Each overlaps that function winding outside all connects corresponding driver or by ac power supply, and all can work independently motor is run well.
Technical solution of the present invention also comprises: the function winding that respectively overlaps on stator is the parallel setting of homophase.
Technical solution of the present invention also comprises: each overlaps the function winding and all adopts the Y type to connect or all adopt the △ type to connect, and wherein, when adopting the Y type to connect, the central point of each Y type function winding can adopt and connect or disconnected two kinds of patterns at each cover function winding.
Technical solution of the present invention also comprises: each overlaps the function winding all can independently make motor run well.
Compared with prior art, the continuous service ability when major advantage of the present invention is the electric system application is effectively ensured, can satisfy the problem of complicated applications environment and specific (special) requirements application demand, has improved reliability simultaneously.When motor and a plurality of driver construction system, each overlaps that the function winding is independent respectively and directly is connected with driver (structure can referring to accompanying drawing 3), by each driver provide with frequently, the homophase power supply, system configuration is simplified, the reliability height; When system moved, no matter be that motor or driver passage break down, then system can also keep normal operation under not participation of faulty channel situation.When connecting and composing system (structure can referring to accompanying drawing 4) like motor of the present invention and single driver or AC power; The parallel winding of each cover can be connected with driver or AC power in parallel connection; When system moves; Like a certain cover winding problem is arranged, system is under the situation that has the problem winding not participate in, and other winding still can be kept system and run well; The reliability and the continuous service ability of system are greatly improved equally, need increase the problem of complicated front network when also having solved simultaneously by a plurality of driver drives heavy-duty motor.

Embodiment
Below will combine accompanying drawing that content of the present invention is further specified, retouch the embodiment that shows but real protection range of structures of the present invention is not limited in accompanying drawing.
Referring to accompanying drawing; Motor according to the invention is except that stator winding; All the three phase alternating current motor with each quasi-tradition is identical for the structure of part such as rotor, support, and its difference is that the conventional motors stator winding is made up of a cover winding, and motor windings of the present invention is made up of the parallel function winding that is no less than 2 covers.Be provided with on the structure, the method for attachment of respectively overlapping the function winding among the present invention is similar with the method for attachment of conventional motors winding (connecing the winding of method like Y type, △ type etc.), and each overlaps the function winding and is homophase, concurrency relation.Each overlaps the function winding when adopting the Y type to connect, and the central point of each Y type function winding can adopt and connect and disconnected two kinds of patterns.Each overlaps the function winding and is connected with driver or AC power and can adopts dual mode: when motor was connected with a plurality of low capacity drivers, each overlaps, and the function winding is independent respectively directly to be connected with the low capacity driver, and each driver provides with frequency, homophase power supply during work; When motor was connected with single driver or AC power, each overlapped the parallel connection of function winding and is connected with driver or AC power.The application example of concrete drive system can be referring to accompanying drawing 3 and accompanying drawing 4.
