AC Servo Motor with STM32f407

[tnishanthraj]

Hello guys, I'm looking to control an AC Servo motor with STM32f407- Discovery kit. There are a lot of resources for DC motor, but i couldnt find many for AC Servo. Can anyone suggest on how to approach or share me some resources? Thanks in advance.

Hello @tnishanthraj ,

Do you have any reference of the motor you want to drive ?

Are you sure it is not a BLDC motor or a PMSM motor ?

Yes, I'm using ELM2H-0400LA60F AC Servo Motor with EL7-RS400P Servo Drive.

Hello @tnishanthraj ,

If you use a EL7-RS400P Servo Drive, what is the purpose of the STM32F407 Discovery kit ?

Your motor seems to be a PMSM (Permanent Magnet Surface Mounted), and can be driven by FOC algorithm.

We provide a Motor Control SDK downloadable here. But as stated in the name, it is a development kit providing motor control FOC algorithms and API to allow you to develop a motor control application on top of it. 

Regards

The control an AC Servo motor with the STM32f407 Discovery kit, start by understanding the motor's specifications and interface requirements. Implement a control algorithm, possibly using a Proportional-Integral-Derivative (PID) controller, tailored to the servo's characteristics. Leverage STM32's PWM capabilities for precise motor control.
