AM13E23019: Delta-Sigma Modulator Current ADC compatibility

Simon Björklund

Part Number: AM13E23019
Other Parts Discussed in Thread: AMC0106M05,

Hello TI

 

Is the AM13E23019 MCU able to utilize the AMC0106M05 Current Sensing Delta-Sigma ADC for current sensing for the InstaSPIN motor library? Or is it required to use the MCU ADCs with an current sense OPAMP as the INA241?

 

Also, Is AM13E23019 with InstaSPIN/FOC library able to do sensorless FOC at slow/zero speeds? Or is encoder required to achieve slow speed performance?

 

Thank you

Best regards

    Hi,

    AM13E23019 does not have Delta sigma filter module(SDFM) , Hence we cannot use it . I recommend going with the current sense opamp approach.

    We have achieved stable sensorless control for electrical speed of 5 Hz but, this varies with the type of motor being used and the inductance of the motor. Encoder is preferred approach for ultra low speeds close to 0Hz..

    Hope these answered your questions!!

    Best Regards,
