Hi again,
I need advice as to which way to connect up the motors please.
The motors are 1.89 NM 8 wire units and can be connected as either Bipolar series or parallel.
In series the current requirement is 2.1A per phase with an inductance of 6.4 mH and resistance of 2 Ohms, if connected in parallel it will draw 4.2 Amps but with an inductance of 1.6 mH and resistance of 0.5 Ohms. I have limited the current of the TB6560 driver board to 75% of its nominal max of 3 Amps for safety ie: 2.125 Amps.
Could I just connect the motors in parallel even though there is not enough current flowing through the board or just opt for a series connection and let driver deal with the high inductance.
I know it is easier to drive the motors if connected in parallel due to very low inductance but could the lack of current reduce the performance unacceptably or drive the board in to melt down ?
Any help is welcome.
Best regards,
A.G
