Abstract
The utility model relates to a motor rotor assembly, comprising a rotor shaft, rotor sheets and a commutator. The rotor sheets superpose together and are sleeved on the rotor shaft. The rotor sheet is provided with trunkings. The commutator is provided with reversing hooks. The motor rotor assembly is characterized in that the number of the trunkings of the rotor sheets is twelve, and the number of the reversing hooks of the commutator is the same with the number of trunkings of the rotor sheets. In a structure of the motor rotor assembly, the number of trunkings of the rotor sheets is the same with the number of the reversing hooks of the commutator, thereby increasing a wire diameter of armature winding, so that output power of a motor is improved and whole performance of the motor is improved.
Description
Technical field
The utility model relates to a kind of motor, in particular Rotor Assembly.
Background technology
Motor generally is to be made of rotor, stator and commutator, and its rotor is comprised of armature spindle, rotor sheet, and rotor sheet is superimposed with together and is sleeved on the armature spindle, is provided with wire casing at rotor sheet, is used for coiling, and commutator segment also is installed on the armature spindle.At present, the wire casing number is provided with 8 on the rotor sheet of this motor, and commutator then is the commutator that adopts 16 commutation hooks, thereby, when coiling, need two commutation hooks are moved in the wire casing simultaneously, so just cause the copper factor of rotor sheet too high, the wire diameter of coiling is meticulous, rotor is easy to burn out, and under the condition of the identical number of turn, the power output of motor is not high.If the wire casing number is improved, too little at wire casing, the wire diameter of coiling is still meticulous, if the commutator hook is reduced, then again carbon brush can't be installed.Therefore, just need to design one so that wire casing number and the rational Rotor Assembly of commutator hook number.
Summary of the invention
In view of the deficiency that background technology exists, the technical problems to be solved in the utility model provides a kind of motor not easy burn-out and the high electronics rotor assembly of power output.
For this reason, the utility model adopts following technical scheme to realize: a kind of Rotor Assembly, comprise armature spindle, rotor sheet and commutator, described rotor sheet is superimposed and is sleeved on the described armature spindle, has wire casing on the described rotor sheet, described commutator has the commutation hook, it is characterized in that the wire casing of described rotor sheet has 12, and the commutation hook of described commutator segment is identical with the number of described rotor sheet wire casing.
Described armature spindle is provided with jump-ring slot, is provided with jump ring in the described jump-ring slot.
This structure of the present utility model, with the number of rotor sheet wire casing and commutation hook be set as identical after, thereby, during coiling, the corresponding rotor sheet wire casing of commutation hook, the copper factor of wire casing can be not too high, and simultaneously, the wire diameter of coiling can strengthen, so, the rotor of motor is easy burn-out not, and under the identical number of turn, has improved the power output of motor.
Description of drawings
The below further describes details of the present utility model more by reference to the accompanying drawings.
Fig. 1 is overall construction drawing of the present utility model;
The structure chart that Fig. 2 is the utility model coiling on the rotor sheet;
Fig. 3 is the utility model commutation hook schematic diagram corresponding with wire casing.
Embodiment
With reference to accompanying drawing, this Rotor Assembly, comprise armature spindle 1, rotor sheet 2 and commutator 5, described rotor sheet 2 is superimposed and is sleeved on the described armature spindle 1, has wire casing 6 on the described rotor sheet 2, after rotor sheet is superimposed, wire casing 6 is all on the same straight line, described commutator 5 has commutation hook 4, and the wire casing 6 of described rotor sheet 2 has 12, and the number of wire casing 6 is identical on the commutation hook 4 of described commutator 5 and the described rotor sheet 2.Like this, commutation hook 4 and wire casing 6 carry out corresponding after, coiling 7 on commutation hook 4 moves into a wire casing 6, to reduce the copper factor of wire casing 6 interior coilings, and can improve the wire diameter of coiling 7, in the situation of same number of turns, and then can improve the power output of motor, to solve the meticulous too high deficiency that causes easily rotor to burn out of copper factor that causes of coiling in the background technology.Described armature spindle is provided with the jump-ring slot (not shown), be provided with jump ring 3 in the described jump-ring slot, commutator 5 is installed on the armature spindle 1, by stopping of jump ring in the jump-ring slot 3, prevent that commutator 5 from endwisely slipping, the commutation hook 4 that keeps commutator 5 with move into 7 and stablize and are connected.This structure of the present utility model under the identical number of turn, has improved the power output of motor effectively, has improved the useful life of motor, has very good result of use.
Claims (2)
1. Rotor Assembly, comprise armature spindle, rotor sheet and commutator, described rotor sheet is superimposed and is sleeved on the described armature spindle, has wire casing on the described rotor sheet, described commutator has the commutation hook, the wire casing that it is characterized in that described rotor sheet has 12, and the commutation hook of described commutator segment is identical with the number of described rotor sheet wire casing.
