I am thinking of purchasing the
powering Mini Cim motors?
(Mini Cim specs)
Battery In: 12V DC
Outputs: Shaft size - 8mm (0.314in) with 2mm keyway
Free Speed: 5,840 rpm (+/- 10%)
Free Current: 3A
Maximum Power: 215 W
Stall Torque: 1.4 N-m [12.4 in-lbs]
Stall Current: 89A
Hello @bluedalek!
In order to choose a motor controller you have to consider the nominal voltage and the continuous current. As the specs of the motors you mentioned don’t include continuous operating current, a simple rule of thumb is to estimate it at about 25% of the stall current, so let’s say it’s 22A.
The Cytron 30A 5-30V Single Brushed DC Motor Driver allows controlling a DC motor with voltages between 5 and 30V, a continuous current of 30A, and a peak current up to 80A (for 1 sec). However, if the mini cim motor stalls, those 80A won’t be enough so the motor controller could get damaged.
Some safer options are:
And you can find more in the 30A+ DC Controllers section of the store.
I hope this information can help you out
Let us know if you have further questions
Thank you…Leaning towards the SyRen controller…
