    [0001] [01] The present invention relates to a direct drive seed distributor device and, more specifically, a seed distributor device for sowing, driven by a coaxial electric motor, which comprises a seed distributor disk to capture seeds at from a reservoir and deposit them in a controlled manner in a groove in the ground, where the coaxial electric motor is directly coupled to the distributor disk without the need for intermediate transmission elements, reducers, gears or belts, thus improving the efficiency of the device.
    [0002] [02] In preferred embodiments of the present invention, the means for capturing and releasing the seeds operate through the generation of vacuum or high pressure.
    [0003] [03] Additionally, in preferred embodiments of the present invention it comprises a toroidal electric motor with hollow shaft rotor, through which the seed capture medium is fluidly connected with the vacuum or pressure generating means. Previous art
    [0004] [04] Seeders for row planting or seed planters for single sowing have been widely used for decades. Typically, said machines include at least one rotating disk for holding and supplying the seeds to be planted and means for releasing and driving the seeds to the furrows in the soil at a certain depth and spacing.
    [0005] [05] The rotating discs normally comprise holes, pockets, wedges or teeth to retain the seeds with the help of vacuum or positive air pressure, which is interrupted at a desired point to allow the seed to fall to the conduction medium to the ground.
    [0006] [06] The most well-known sowing machines comprising a plurality of spreading discs depend on a single drive set to rotate all discs simultaneously. In the case of machines that have a large number of distributor discs, for example, 20 or more, said drive set is bulky, expensive and complicated, does not allow the individual adjustment of the rotation of each distributor disc, which is necessary on occasions where the machine is not expected to follow a straight path, where the most external seeding devices travel greater distances than the more internal ones.
    [0007] [07] These disadvantages were addressed through the use of hydraulic systems to drive each disk individually, including sophisticated electronic control means, which require constant and expensive maintenance.
    [0008] [08] Some recent developments in seeding machines replace the said hydraulic system with individual electric motors, which results in simpler and more economical equipment, especially as revealed in WO 2012/142607 A1, where the motors are connected to the disc shafts distributors.
    [0009] [09] However, there is still a need for simpler distribution devices, with lower power requirements and lower construction and maintenance costs. Brief description of the invention
    [0010] [010] The above disadvantages can be overcome and these needs can be satisfied through the use of a seed metering or distribution device driven by a brushless, high torque direct current motor with a high torque and ring or toroidal shape. comprising a hollow or ring shaft rotor, coaxially coupled to the distributor disk.
    [0011] [011] The application of a high torque motor coupled directly to the rotating working elements of the seed distributor device of the present invention reduces the need for reductions, gear transmission, belt transmission and other auxiliary transmission components as found in the transmission devices. distribution of seeds known in the art. This reduction or complete elimination of mechanical transmission elements between the power source and the load implies a substantial reduction in power loss, which in turn results in an improvement in the loss of output power, reduction of noise and vibrations and greater overall efficiency.
    [0012] [012] Additionally, the reduction or elimination of auxiliary transmission elements greatly reduces maintenance costs and complexity, while improving the operational life of the device.
    [0013] [013] In addition, the slender design of the high torque, ring motor allows the motor to be partially or completely arranged inside the seed distributor housing, reducing the overall size of the device and partially or completely protecting the motor from external elements .
