stm32 motorkit: Direct Drive High Torque

Hello,

Is it possible to control a direct drive motor (ETEL TMM140-050xxx , BusVoltage 42V, continuous current 2,77Arms, E.Inductance 56 mH, E.Resistance 11,3Ohm, 11 Polepairs .......) with the STM32 EvalMotorKit ?

Next problem is: I need a controller for 2 Direct Drive motors for a telescopic mount. The minmal speed is 15arcsec/sec i.e 1 revolution/day, the maximum slew speed should be 15 degree/sec. With the FOCGUI-Tool are this extremly parameters not possible.

Who can hel me ?

Bestregards

Hello,

about your first question, no problem you can run the motor with the STM32 MC Kit.

As for your second question, may I know what kind of sensors you're using to have a such precise speed regulation? Do you have any mechanical gear? If not we need to manually edit the .h file generated by the GUI.

Regards,

Billino

Hello Billino,

thanks for your reply. For my work in progress I´ve select an programmable high resolution encoder (MicroE-Systems: MercuryII 5000) with A quadB, Index puls output, look at the attachment).

Which strategy of PID regulation is meaningful at this very low speed ?

Thanks and

best regards
