Abstract: The dual-channel rotary encoder decoding microsystem is primarily applied in multi-axis servo control systems for robots,drones,electric vehicles,and other applications,which can provide multi frequency and multi amplitude excitation signals for the rotary transformer, which is installed inside the motor. It can demodulate the real-time feedback sine and cosine signals of the rotary transformer,calculate the real-time angle of the current motor rotation,and transmit the angle data to the controller through serial or parallel means to complete the closed-loop control of the motor. With the continuous development of contemporary technology,the market ' s demand for product miniaturization is becoming higher,
and the trend towards integration is becoming more apparent. To meet the needs of high-integration products in terms of space adaptation,weight control, reliability enhancement, and cost optimization, the dual goals of system compactness and economy are achieved by reducing wiring and connecting components. This article introduces a microsystem that can simultaneously drive and decode two rotary transformers from three dimensions, principal design,simulation verification,and packaging process. The integration level of this system is nearly 50% higher than that of traditional discrete solutions, effectively solving the adaptation challenges faced by traditional solutions in compact space scenarios. This module not only meets the needs of users for miniaturization,but also does not need remanufacture of wafers,and has a short development cycle,and costs low relatively.
