Description
Technical field
The utility model is a kind of motor, and particularly a kind of nothing starts the no electric capacity series excited machine of bag.
Background technology
DC motor is different with the mode of armature circuit binding because of field circuit, can be divided into separate excited motor, compound motor and series-wound motor.Each type electric tool adopts the power source of series excited machine as it mostly both at home and abroad at present, the service condition of this motor is very harsh, its no-load speed is generally all about 20000r.p.m, have up to 30000r.p.m or more than, starting is frequent, vibration is violent, and the bit freezing phenomenon often takes place, this moment, stalling current was bigger 6～7 times than rated current, cause the hurried rising of electric machine temperature rise, evidence, its transient heat impact temperature can reach 200 ℃ even higher.Under the comprehensive function of factors such as high centrifugal force that high temperature, high rotating speed produced and vibration, impel this motor premature damage.Fact proved that electric tool fault 70～80% is caused by the series excited machine damage.The damage of series excited machine generally has the reason of two aspects, and the one, the insulation system defectiveness, but the comprehensive function of high mechanical stress is lacked the ability of resisting.Existing series excited machine does not reach requirement just because of insulation property and anti-high mechanical stress performance, so cause the electric tool fault higher.
Summary of the invention
The purpose of this utility model is in order to overcome the existing higher defective of series excited machine fault, to invent the no electric capacity series excited machine of nothing startup bag of the big good insulation preformance of a kind of starting torque.
The purpose of this utility model realizes as follows: described nothing starts the no electric capacity series excited machine of bag, comprise output bracket, input rack, stator core, stator support, rotor core and rotating shaft, output bracket, input rack is connected the back with stator by screw and forms a cavity, being provided with stator support in the cavity plays a supportive role to stator, rotating shaft is located on output bracket and the input rack, it is characterized in that: rotor core is fixed in the rotating shaft by double insulating layer, the two ends of rotor core are respectively equipped with the cured plate of insulation, rotor core is provided with rotor, is provided with rotor paper in the rotor; In the rotating shaft symmetry be provided with two commutators, in the input rack symmetry be provided with two brush boards, brush board is provided with carbon brush component and wire assembly, wire assembly is electrically connected with commutator by carbon brush component.
Good effect of the present utility model is as follows: the utlity model has good startup and speed adjusting performance, the rotating speed height, starting torque is big, power is big; Owing to be not activated bag, do not need electric capacity yet, so simple in structure, volume is little, in light weight.
