The EVALKIT-ROBOT-1 is a plug-and-play solution aimed to help users easily approach the world of precise positioning and high-end motion in servo drives and robotics. A maxon 100-Watt BLDC motor with built-on 1024-pulse incremental encoder is included in the kit, embodying the company’s expertise in magnetic design in motors that ensures smoothness and balance to allow fine control even at low rotor speeds.
The servo control board supplied with the kit contains ST’s STSPIN32F0A intelligent 3-phase motor controller and a complete inverter stage built with ST power transistors ready to connect to the motor. Motor-control firmware is also included, making it easy for users to start the motor and begin sending commands.
ST’s STSPIN32F0A system-in package contains critical circuitry for motor control, including an STM32F031C6* microcontroller and three-phase inverter driver in a compact 7mm x 7mm VFQFPN package. The microcontroller comes loaded with plug-and-play firmware for MODBUS communication and field-oriented control (FOC) with precise positioning capabilities. Power management and current sensing circuitry are also embedded in the device making it more flexible and versatile.
The maxon EC-i 40, 40mm-diameter, 100-Watt brushless (BLDC) motor embeds a maxon ENX 16 EASY 1024-pulse incremental encoder for precision control. Hall sensors for detecting rotor position are included. The motor features an optimized design for high output torque with low cogging torque, which permits smooth motion across the speed range and enhances positioning precision.
