STMicroelectronics: Evaluation Kit ROBOT-1
Ready-to-use servo brushless solution

The EVALKIT-ROBOT-1 is an evaluation kit offering a ready-to-use servo brushless solution. It is a result of STMicroelectronics and maxon collaboration and includes a 3-phase BLDC motor from maxon, rated 100W, and a compact servo control board. Thanks to the high integration level of the STSPIN32F0A, the control board provides a versatile inverter stage, the analog circuitry implementing current sensing, power management and a full set of protections and a Cortex-M0 microcontroller performing a Field-Oriented Control with closed-loop positioning. All packed into a 40 mm x 40 mm footprint. The maxon EC-i 40 motor, thanks to the optimized magnetic design, offers a very high torque density and very low cogging torque. In combination with the maxon ENX 16 EASY 1024 pulses incremental encoder, it is an excellent choice for reliable, robust and high-precision position and speed control.
