EVALKIT-ROBOT-1: 100 W, 12 ~ 45 VDC BLDC Driver with RS-485

EVALKIT-ROBOT-1 is an evaluation kit offering a ready-to-use servo brushless solution.

Thanks to the high integration level of the STSPIN32F0A, the control board provides a powerful power stage, the analog circuitry implementing current sensing and overcurrent protection 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 circuit, 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.

The following material is required to make the system operative:

• One 36 V / 120 W DC power supply

• A RS485 2-wire serial port

• A communication software based on MODBUS protocol
