We have design and developed FOC control for PMSM motor using TI Sensor-ed PMSM control guide from TI.
Everything works perfect on loaded condition but when we run the motor on unloaded condition, it runs at max RPM.
We are giving the torque command via an ADC Pot. Our requirement is to control the torque of the motor but when there is no load it should run as per the ADC pot command.
Zero pot means - Zero speed , mid Pot - mid speed and full pot means full speed.
Please give me some suggestion to control motor as per above conditions.
