概要

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.

  • 特徴

    • Compatible with automotive control board STEVAL-TTM004V1 and STEVAL-TTM002V1
    • Supported by the SPC5STUDIO MC tool
    • 12V input voltage for a wide sinusoidal excitation signal
    • Arduino connector for a full compatibility with the STM32G474RE
    • Different outputs for a better noisy immunity (Sine and cosine signals generated by the resolver on motor)
    • Suitable to manage field oriented control (FOC) algorithms
