Reference design drives servo motors
ST’s EVLSERVO1, a turnkey reference platform for servo motor control, enables sensorless or sensored field-oriented control (FOC) with one, two, or three shunts. It drives three-phase brushless motors up to 2 kW with the provided heatsink or 3 kW with an external fan.
The reference design features the STSPIN32G4 three-phase motor controller with an embedded STM32G4 MCU, enabling advanced position and torque control algorithms, as well as six-step control modes. It pairs with a three-phase power stage optimized for nominal bus voltages from 24 V to 48 V. The power stage, stacked with the STSPIN32G4 to maximize power density, includes six pairs of paralleled MOSFETs with low RDS(ON) of 3.2 mΩ.
With a compact 50×80×60-mm form factor, the EVLSERVO1 enables designers to develop and prototype motor control applications such as industrial and home automation, home appliances, servo drives, e-bikes, and service robots. Additionally, ST offers the X-CUBE-MCSDK for easy configuration of motor control firmware parameters.
The EVLSERVO1 reference design is available now from the eSTore and ST distributors for $168.
