Abstract
Improvement formula synchronous machine, it includes stator, synchronous motor rotor, rectifier, improvement formula synchronous machine include 2 motors more than extremely, its characterized in that: the field power supply winding is along winding each inslot of looking at and appraising each utmost point winding at the stator. The utility model discloses improvement formula synchronous machine motor of the same kind with the conventionality compares, owing to there has been its application range of synchronous torque of self -starting just also wide.
Description
Technical field
The utility model relates to a kind of improvement opportunity of synchronous machine, particularly a kind of improvement type synchronous machine efficiently.
Background technology
At present, the nameplate of the every platform of conventional synchronous motor all indicates technical indicator and the requirement of single-phase or three-phase, particularly the power factor of generator indicates delayed 0.8, manufacturing and designing routinely, synchronous machine can only be made generator and use, because be not activated torque so can not imitate asynchronous motor AC power and directly start.
Summary of the invention
The purpose of this utility model to provide a kind of high efficiency improvement type synchronous machine, changes the structure of former field power supply with transformer principle, and implementation stator winding combines with field power supply winding and carries out Integral design, makes rotor have the synchronous torque of self-starting.
The utility model is such structure: improvement type synchronous machine, it comprises whole the accessories such as stator, synchronous electric motor rotor, winding, field power supply winding, rectifier, threephase stator iron core 24 groove 4 pole single-chain type winding is changed system into double-deck with groove single-chain type winding by transformer principle, described improvement type synchronous machine comprises single-phase or that three-phase 2 is extremely above motor, it is characterized in that: field power supply winding is along in the groove around stator each mutually each pole winding.
Described improvement type synchronous machine, is characterized in that: field power supply winding along in the groove of stator each phase N pole winding not around S pole, or field power supply winding along in the groove of stator each phase S pole winding not around N pole.
The utility model improvement type synchronous machine motor ratio similar with routine, because its scope of application of synchronous torque having self-starting is also just wide.
Accompanying drawing explanation
Fig. 1 is the three-phase 24 groove 4 pole individual layer chain type rated power winding U phase of the utility model improvement type synchronous machine and field power supply winding A phase demodulation schematic diagram (stator winding V phase, W phase are omited, and field power supply winding B phase, C phase are omited).
In Fig. 1 figure, 1 be rated power winding terminal head end U1,2 is field power supply winding terminal head end A1, and 3 are rated power winding terminal end U2,4 is field power supply winding terminal end A2.
Embodiment
According to Fig. 1 three-phase 24 groove 4 pole individual layer chain type rated power winding U phase and field power supply winding A phase demodulation schematic diagram, after first embedding rated power winding U phase by 24 groove individual layer chain type coil-inserting methods, embed field power supply winding A phase.
1, U phase 4 coils are embedded stator core 1 and 6 groove, 7 and 12 grooves, 13 and 18 grooves, 19 and 24 grooves respectively, 6 slot coils are connected with 12 slot coils, 7 slot coils are connected with 13 slot coils, 18 slot coils are connected with 24 slot coils, draw leading-out terminal head end U1 from 1 groove, draw leading-out terminal end U2 from 19 grooves.
2, embed V phase, W phase according to the rule of U phase and the method for attachment of coil successively by 120 electrical degrees of being separated by, then draw V phase leading-out terminal head end V1, end V2 and W phase leading-out terminal head end W1, end W2 respectively.
3, according to above-mentioned 1,2, the coil-inserting method of stator winding embeds stator core 1 and 6 groove, 7 and 12 grooves, 13 and 18 grooves, 19 and 24 grooves respectively excitation winding A phase 4 coils, 6 slot coils are connected with 12 slot coils, 7 slot coils are connected with 13 slot coils, 18 slot coils are connected with 24 slot coils, draw leading-out terminal head end A1 from 1 groove, draw leading-out terminal end A2 from 19 grooves.
4, successively embed B phase, C phase with the method for attachment of coil by 120 electrical degrees of being separated by according to the rule of A phase, then draw B phase leading-out terminal head end B1, end B2 and C phase leading-out terminal head end C1, end C2 respectively.
5,6 leading-out terminals extractions of three-phase stator winding U phase, V phase, W phase are connected by star or delta connection with connection box for motor.
6,6 leading-out terminals extractions of field power supply three-phase windings A phase, B phase, C phase are connected by star or delta connection.
The junction of the three-phase electricity 7, the three-phase electricity of field power supply inputted with rectifier is connected.
8, the direct current both positive and negative polarity after rectifier rectification is connected with the excitation winding of rotor, forms improvement type synchronous machine.
In sum: the technology of the utility model improvement type synchronous machine can be widely used in exploitation and the manufacture of single-phase, three-phase the two poles of the earth or multipole synchronous machine.
It is identical with the technology of existing synchronous machine and asynchronous motor that the utility model does not state part.
