Abstract
The utility model discloses a novel ventilation hole structure of a three-phase asynchronous motor, which comprises a rotor sheet, and each ventilation hole (1) on the rotor sheet has a trapezoidal structure. In the structure adopted by the utility model, the prior ventilation hole structure on the rotor sheet is changed into a trapezoid, so that the ventilation and heat exchange area of the rotor sheet is enlarged, consequently, the temperature rise of the motor is reduced, and the operation performance of the motor is ensured. The iron core of the motor also can be shortened under the condition of equal temperature rise, so that the production cost of the motor can be reduced and the economic benefit of the product can be increased.
Description
Technical field
The utility model relates to a kind of motor technology, especially relates to a kind of novel ventilated pore structure of threephase asynchronous.
Background technology
The rotor of motor is the critical piece of motor, constitute by parts such as armature, commutator (claiming commutator again) and rotating shafts, wherein armature is made up of armature core and armature winding two parts, armature core is built up by rotor punching, motor is in long-time operation process, can produce the problem that temperature raises, the temperature rising can have influence on the runnability of motor.At present, all be provided with the ventilation hole structure on the rotor punching of motor, the ventilation hole structure can be used for cooling motor, and owing to the circle that is shaped as of tradition ventilation pore structure, the ventilation heat exchange area is smaller, reduces temperature rise to motor and has brought inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of novel ventilated pore structure that can increase the threephase asynchronous of rotor punching ventilation heat exchange area.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises rotor punching, and the ventilation hole on the described rotor punching is a trapezium structure.
The said structure that the utility model adopts changes original ventilation hole structure into trapezoidally on rotor punching, has increased the ventilation heat exchange area of rotor punching, has reduced the temperature rise of motor, has guaranteed the runnability of motor; Also can under equal temperature rise situation, shorten the iron core of motor,, improve the economic benefit of product to reduce the production cost of motor.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model.
Embodiment
By accompanying drawing as can be known, the novel ventilated pore structure of this threephase asynchronous comprises rotor punching, and the ventilation hole 1 on the described rotor punching is a trapezium structure.The ventilation hole of rotor punching upper trapezoid structure can effectively increase the girth of rotor punching ventilation hole, increases the ventilation heat exchange area of rotor core, and the temperature rise of motor is reduced on the original basis.
Claims (1)
1, a kind of novel ventilated pore structure of threephase asynchronous comprises rotor punching, it is characterized in that: the ventilation hole on the described rotor punching is a trapezium structure.
