STMicroelectronics STEVAL-TTM005A Resolver Board

STMicroelectronics STEVAL-TTM005A Resolver Board is specifically designed for developing and testing automotive motor control applications. The board ensures accurate motion sensing based on rotor position estimation with resolver feedback. This rotor position estimation allows excellent control with zero speed, with the most advanced FOC algorithms reducing any torque and speed ripple on the motor. A 12V_DC input and 5V supply the board and include ST’s latest high-precision, low-noise operational amplifiers and an optimized excitation circuit that guarantees a reliable and accurate operation.

The excitation signal, generated by an external compatible control board (STEVALTTM004V1, STEVAL-TTM002V1, or the STM32G474RE connected with the Arduino connectors), is amplified by the TSB582 and able to excite the resolver coil. The two-phase shifted resolver outputs for sine and cosine waves are treated by a TSB514 op-amp and then converted into digital signals by the microcontroller on the control board. With high accuracy and extended compatibility, the board is an essential tool for validating and testing any high-precision system for motion control sensing with high performance thanks to the rotary resolver and best-in-class signal conditioning circuitry.
