Abstract
The utility model relates to a motor with a novel single-layer fractional-slot winding. The motor comprises a stator and a fractional-slot winding, wherein the fractional-slot winding is wound on the stator; the fractional-slot winding is in a single layer; and the slot quantity of each polarity and each phase of the fractional-slot winding is 3/2. The single-layer fractional-slot winding is wound on the stator of the motor, so that an application area of a space inside a motor slot is increased, and the difficulty in embedding wires can be reduced. The motor is simple and practical in structure.
Description
Technical field
The utility model relates to a kind of motor, and the motor with novel individual layer fractional slot winding that especially a kind of rule difficulty is little belongs to technical field of motors.
Background technology
Usually fractional slot winding is made two layer winding on the prior motor, the upper and lower layer in the promptly same groove is many to be made up of out of phase two phase winding limits, thereby the separated insulation mutually of palpus cushioning, motor slot space utilization area is reduced, and the rule difficulty is strengthened.
The utility model content
The utility model purpose is to have proposed the little motor with novel individual layer fractional slot winding of a kind of rule difficulty for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of motor with novel individual layer fractional slot winding comprises stator, fractional slot winding; Said fractional slot winding is wrapped on the stator; Said fractional slot winding is an individual layer.
Preferably, every extremely every phase groove number of said fractional slot winding is 3/2.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
Twine the fractional slot winding of individual layer on the stator of the described motor with novel individual layer fractional slot winding of the utility model, thereby increased the usable floor area in space in the motor slot, it is little to have reduced the rule difficulty; The utility model scenario-frame is simple, practical.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the distribution map of the novel individual layer fractional slot winding of the utility model.
Embodiment
Said a kind of motor with novel individual layer fractional slot winding of the utility model comprises stator, fractional slot winding; Said fractional slot winding is wrapped on the stator; Said fractional slot winding is an individual layer; Every extremely every phase groove number of said fractional slot winding is 3/2; Present embodiment is very routine with 36 grooves 8 with this patent:
Groove is counted z1=36
Parallel branch is counted a=1 (can also be connected into a=2 as required)
Number of poles 2P=8
Number of phases m=3
Every extremely every phase groove is counted q=36/8X3=3/2
Every groove number that occupies mutually: 12
α=8X180/36=40 ° of ele of groove electrical degree.
Connect method: Y
Every distribution in 36 grooves, and each phase winding arranges and see accompanying drawing 1, the person that has the horizontal line on the letter among the figure is current opposite in direction.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
Twine the fractional slot winding of individual layer on the stator of the described motor with novel individual layer fractional slot winding of the utility model, thereby increased the usable floor area in space in the motor slot, it is little to have reduced the rule difficulty; The utility model scenario-frame is simple, practical.
Below only be the concrete exemplary applications of the utility model, the protection range of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
Claims (2)
1. the motor with novel individual layer fractional slot winding comprises stator, fractional slot winding; Said fractional slot winding is wrapped on the stator; It is characterized in that: said fractional slot winding is an individual layer.
