Applications

Automotive
Motor Control

The STEVAL-TTM005A is a powerful tool that has been specifically designed fordeveloping and testing automotive motor control applications.
The board ensures accurate motion sensing based on rotor position estimation withresolver 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 highprecision, low-noise operational amplifiers and an optimized excitation circuit thatguarantees a reliable and accurate operation.
The excitation signal, generated by an external compatible control board (STEVALTTM004V1, STEVAL-TTM002V1, or the STM32G474RE connected with the Arduinoconnectors) 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 aTSB514 op amp and then converted into digital signals by the microcontroller on thecontrol 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 highperformance thanks to the rotary resolver and a best-in-class signal conditioning
circuitry.
