Abstract
The utility model relates to the technical field of gearless permanent magnet synchronous outer rotor traction machines for elevators and discloses a rotor for an outer rotor traction machine. The rotor comprises a rotor cylinder, a permanent magnet and a rotor core, and is characterized in that the rotor cylinder is made into a cylinder by employing cast iron; the rotor core is formed by laminating the quartered fan-shaped silicon steel sheet punches and is arranged in the rotor cylinder; a plurality of square holes are formed in the rotor core along the circumference; the permanent magnet is embedded into the square holes; and an outer edges of the inner side of the permanent magnet is arc. The rotor is reasonable in design, simple in structure, easy to manufacture and low in cost, the mounting performance of the magnet is reliable, and the electrical properties of the traction machine are improved.
Description
Technical field
The utility model relates to the technical field of elevator with gearless permanent-magnet synchronization external-rotor traction machine, specifically a kind of rotor of external rotor traction machine.
Background technology
Externally, stator is in inside for the rotor of external rotor traction machine.During work " the shell rotating shaft does not turn ", traditional outer rotor designs is that rotor design is become to tubbiness, and material adopts cast iron or cast steel, and permanent magnet is arranged on inwall and sticks with glue and connect along garden week distribution, and each magnet is isolated with copper bar and compressed.Because the housing magnetic property is bad, reduce the traction machine electrical characteristic, magnet is installed inconvenient, and poor reliability, easily cause magnet to come off and cause quality accident during rotor.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, provides a kind of reasonable in design, simple in structure, easy to manufacture, and cost is low, and permanent magnet is easy for installation, steady quality, the rotor of the external rotor traction machine that reliability is high.
The technical scheme that the utility model adopts is: a kind of rotor of external rotor traction machine, comprise rotor cylinder, permanent magnet, rotor core, it is characterized in that the rotor cylinder adopts cast iron to make cylindrical shape, rotor core adopts the fan-shaped silicon steel punched chip of the quartering to be overrided to form, rotor core is in the rotor cylinder, in rotor core, along being provided with a plurality of square holes on circumference, permanent magnet is embedded in square hole, and the inboard outer rim of permanent magnet is circular arc.
Adopt silicon steel sheet can increase the electric property that magnetic permeability is conducive to traction machine, magnet steel is embedded to core interior and can eliminate the magnet steel hidden danger that comes off.Rotor core is made quartering fanning strip, can improve the stamping-out rate; The inboard outer rim of permanent magnet is the waveform that circular arc can be improved breath magnetic field, makes its more approaching sine wave.Permanent magnet embeds rotor core inside, the permanent magnet hidden danger that comes off while eliminating rotor.The utility model is reasonable in design, simple in structure, easy to manufacture, and cost is low, and the magnet installation capability is reliable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Mark in figure: 1, rotor cylinder, 2, permanent magnet, 3, rotor core.
Embodiment
From Fig. 1,2, a kind of rotor of external rotor traction machine, comprise rotor cylinder 1, permanent magnet 2, rotor core 3, rotor cylinder 1 is to adopt cast iron to make cylindrical shape, rotor core 3 adopts the fan-shaped silicon steel punched chip of the quarterings to be overrided to form, rotor core 3 in rotor cylinder 1, in rotor core along being provided with a plurality of square holes on circumference, permanent magnet 2 is embedded in square hole, and the inboard outer rim of permanent magnet is circular arc.The utility model is reasonable in design, simple in structure, easy to manufacture, and cost is low, and the magnet installation capability is reliable.
