Main technological innovations The motor design of this project adopts the advanced finite element analysis magnetic circuit optimization design to optimize the electromagnetic parameters of the motor so that the motor parameters and new energy are completely matched with the servo driver. Effectively reduce product volume, reduce product cost, increase load rate and energy-saving effect.
The motor output feedback component of this project selected a high-precision new magnetoelectric encoder to achieve high-resolution (15-bit) and high-precision (14-bit, 16384-line) angular output, which meets the motor's high-precision position detection in harsh environments. The request.
In this project, the stator core of the motor adopts the design of N plug-in structure and cold extrusion shell (the surface is equipped with heat sink and heat dissipation corrugation), which makes the motor concentrated winding design, reducing the length of the winding end, and the winding coefficient is high. Less material, thus reducing the size of the motor. It is more convenient in terms of capacity planning, improving the ability of the product to adapt to the market, and its appearance is beautiful and delicate.
The motor of this project has applied for an invention patent and many utility model patents and has been authorized.
