Re:Motor control kits...

Dear all,

 

              I would like to know whether we can connect 12V motor and 48V motor both BLDC/PMSM to low voltage motor control kit because it's coming along with dedicated 24V DC adapter only. Also tell what hardware change we want to do, to connect 110V BLDC to high voltage motor control kit.

Will high voltage kit itself support 48V BLDC motor? That means irrespective of the kit all are based upon how much external DC voltage we are giving. is it the case?

 

Regards

Saravanakumar...

    The inverter output needs to match with the motor maximum voltage ratings to avoid insulation failures. These kits are provided for the ease of software development and should be utilized for that purpose only. In general, during software development, you will be okay to use a motor with higher voltage ratings with an inverter having a lower voltage output for example a 48V motor should be okay with a 24V inverter... I would be careful and will try to avoid using a 12V motor with a 24V inverter.  Now, for a 110V motor you will need an inveter capable of handling 110V input ... I believe TI has a high voltage motor control kit. In general you will need to select appropriately rated input rectifier, DC bus caps, IGBTS etc to handle 110V.
