This compact resolution provides high-precision place and velocity management, integrating the superior motor controller for seamless FOC. 

The EVALKIT-ROBOT-1 is a complete reference design for a servo brushless resolution. It provides an entire bundle for these seeking to implement high-precision place and velocity management of their purposes. Central to this design is the STSPIN32F0A, a complicated 3-phase motor controller that integrates a Cortex-M0 microcontroller. This microcontroller executes Discipline-Oriented Management (FOC) with closed-loop positioning, making certain correct and responsive management of the motor. The reference design provides an entire resolution for high-precision motor management, combining a robust and built-in management board with a high-performance motor and encoder. This design is well-suited for purposes requiring dependable and correct positioning and velocity management.

The reference designs by ST Microelectronics energy stage can deal with as much as 36V and 6A peak, offering ample energy for a variety of purposes. The inclusion of STL7DN6LF3 Twin N-channel MOSFETs, rated at 60V and 35mΩ, additional enhances the design’s energy dealing with capabilities. Moreover, the board incorporates corridor sensors and implements present sensing and overcurrent safety, making certain protected and dependable operation. The motor chosen for this reference design is the Maxon EC-i 40, a 100W 3-phase brushless DC motor recognized for its excessive torque density and low cogging torque. When paired with the Maxon ENX 16 EASY 1024-pulse incremental encoder, this motor offers distinctive accuracy and robustness, making it a superb selection for demanding positioning and velocity management duties.

Communication with the management board is made straightforward by means of the RS-485 interface, utilizing the MODBUS protocol, permitting for seamless integration into quite a lot of techniques. The compact footprint of the board, measuring simply 40mm x 40mm, makes it appropriate for purposes the place house is a premium. The firmware, a key part of this design, offers an instance implementation of positioning management based mostly on the FOC library. This firmware is appropriate with a number of toolchains, together with IAR Embedded Workbench, and KEIL-ARM µVision but in addition helps MODBUS RTU communication, making certain seamless integration with current techniques, a testomony to the pliability of our design.
