Motor position estimation with resolver board reading - STEVAL-TTM005A
Introduction
The
STEVAL-TTM005A
is a powerful tool that has been 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 to obtain an excellent control since zero speed, with the most advanced F.O.C. algorithms
reducing any torque and speed ripple on the motor.
The board is supplied by a 12 V dc input and 5 V and includes 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 (STEVAL-TTM004V1, STEVAL-TTM002V1, or the
STM32G474RE
connected with the Arduino connectors) is amplified by the
TSB582
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 its 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 a best-in-class signal conditioning
circuitry.
