Abstract
The utility model discloses an assembly-type stator iron core. The stator iron core is an annular stator iron core formed by connecting three pieces of 120-degree laminating sheet units formed by dividing a circle into three parts equally along the periphery in sequence. Each of the laminating sheet units is formed by laminating and punching a plurality of identical punching sheets together. Each of the punching sheets includes a plurality of stator teeth. The stator teeth are provided with tooth faces and tooth stems for receiving wire coils to wind. The utility model also discloses a stator and a motor adopting the above stator iron core. According to the utility model, by adopting the integral assembly-type stator iron core formed by connecting three 120-degree fan-ring-shaped laminating sheet units in sequence, the utilization rate of punching sheet material is improved and the installation and use are also very convenient at the same time.
Description
Technical field
The utility model relates to technical field of motors, particularly DD direct driving motor technical field.
Background technology
The DD direct driving motor also is direct drive motor because its output torque is large, so some company that this product directly is called moment is servo.Different from traditional motor, the high-torque of this product can directly be connected it with telecontrol equipment, thereby has saved such as gear box, and therefore belt etc. bindiny mechanism just can be called straight drive motors.Owing to adopt direct connected mode, reduced because the position error that mechanical structure produces, so that craft precision guaranteed, reduced in a large number on the other hand installation, the noise during use.
The routine of cylinder than impeller power consumption broken in the appearance of DD motor technology, the DD directly technology of driving has changed and uses belt as the drive manner of medium in the past, and use motor direct-drive, make motor usefulness reach 16 times of conventional motors, energy-conservation about 35%, make roller washing machine also at all inferior unlike rotary drum washing machine aspect energy consumption.The DD technology of directly driving has also solved the difficult problem that the roller washing machine vibrations are large, noise is large simultaneously.
The stator core of traditional DD motor is a drawing, and the blanking of stator core part has become waste material in stamping process, causes the silicon steel sheet utilance low.Granted publication CN201674286, the day for announcing is on December 15th, 2010, denomination of invention discloses a kind of laminate structure of stator iron core of motor of assembled piece type for the Chinese utility model patent of " Segmented motor stator iron core lamination ", by some unit structure, each unit comprises formation its I-shaped yoke section and tooth section, and a plurality of unit are combined into the stator core of finishing.This separately punching out of patent unit reduces the appearance of waste material.But owing to formed by a plurality of I shape unit splicings, when work, produce easily Noise and vibration, affect the performance of motor.On the other hand, the assembly unit between a plurality of unit has also increased the technical difficulty of assembly unit.
Summary of the invention
The purpose of this utility model is to remedy the deficiencies in the prior art, a kind of easy assembly unit is provided and can improves the DD direct driving motor of silicon steel sheet utilance.
Above-mentioned purpose of the present utility model is to realize like this, the assembling-type stator core, described stator core is served as reasons along three sequential annular stator core that are connected to form of 120 ° of stacked wafer cells of circumference trisection, each stacked wafer cells is laminated by some identical punchings and consists of, each punching contains several stator tooths, and described stator tooth has the flank of tooth and supplies the tooth stem of coil winding.
Described each punching both sides are respectively arranged with groove or projection, the projection of described groove or projection and adjacent punching or groove is adaptive is connected.
A kind of assembling-type stator, it comprises aforesaid assembling-type stator core, is wound with the aluminium enamel-covered wire coil windings on the described tooth stem, described coil windings plastic packaging is in closed shell.
Specifically, described closed shell is based on each periphery that is wound in the aluminium enamel-covered wire coil windings of stator tooth tooth stem and seals and mould and extend and the annular plastics housing that forms to the stator tooth coil windings of adjacent both sides.
Preferably, a wherein bottom surface of described closed shell is based on the connecting end surface of adaptive with it clutch and is shaped.
Another bottom surface of described closed shell is based on the connecting end surface of adaptive with it rotor and is shaped.
A kind of DD direct driving motor comprises permanent magnet rotor, also comprises as above arbitrary described assembling-type stator.
The utility model adopts the assembling-type stator core, namely by the sequential complete annular stator core that connects to form of stacked wafer cells of three 120 ° fan annulars, has improved the punching stock utilization, installs and uses simultaneously also very convenient.In addition, the utility model is the coiling aluminium enamel-covered wire on the stator core that assembles, and the aluminium enamel-covered wire coil windings is carried out plastic packaging.Because the aluminium enamel-covered wire material is lighter than copper enamelled wire; cost ratio copper enamelled wire is cheap; therefore reduced the complete machine weight of material cost and motor; make the aluminium enamel-covered wire winding by behind the seal protection by the aluminium enamel-covered wire winding being carried out plastic packaging simultaneously; solve the problem of the easy oxidized corrosion of aluminium enamel-covered wire, thereby realized the application of aluminium enamel-covered wire at the DD direct driving motor.DD direct driving motor of the present utility model can be widely used in draining pump motor of washing machine, dishwasher draining etc.
Below in conjunction with accompanying drawing the utility model is elaborated.
