Problems solved by technology

This method has the following disadvantages: 1. Using the iron core stator structure, there is a certain iron loss and magnetic damping. When the driving power is increased, the iron loss and copper loss will increase and the motor efficiency will be reduced; 2. There is copper loss in the coil winding; 3. The traditional radial magnetic field structure design, the power density and torque volume are relatively small, and the magnetic circuit loss is large
At present, a large number of electronic information products have put forward higher and higher technical requirements for self-generation and self-storage technologies. However, due to the limitations of traditional technical solutions and process design, traditional self-generation (that is, iron-core generators) has Unable to meet market demand, so there is an urgent need for a new generation of self-generation technology to meet market demand

Description

technical field [0001] The invention relates to a power generation device, in particular to a miniature coreless generator applied in the field of high-precision self-power generation. Background technique [0002] Most of the micro-generator technologies used in the industry at this stage still use traditional silicon steel sheets and wound stator structures as core materials, and generate electrical energy output through the transmission structure of motors and gears. This method has the following disadvantages: 1. Using the iron core stator structure, there is a certain iron loss and magnetic damping. When the driving power is increased, the iron loss and copper loss will increase and the motor efficiency will be reduced; 2. There is copper loss in the coil winding; 3. With the traditional radial magnetic field structure design, the power density and torque volume are relatively small, and the magnetic circuit loss is relatively large. At present, a large number of elect...
