Well I plugged in the motor data (EMF calculator) for what I have currently and what I was looking at.
It has me confused....
Current: 84oz Bi_polar, 1.8Deg, 2A, 1.4Ohm Phase resistance...
If I'm reading this correctly......and reduce the motor current to 250ma..my torque slips low at 243, high at 260..
Increase it to 850 and it gets worse....low 175, high 223
Both have peak back emf of 8.2v and 0.8 v.
With the "low current" motor.: 62oz Bi_polar, 1.8Deg, 0.85A , 6.2 Ohm Phase resistance
the motor current to 250ma..my torque slips low at 116, high at 137..
Increase it to 850 and it gets worse....low 58, high 76
Both have peak back emf of 14.4v and 0.9 v.
If I'm interpreting this correctly, the motors I have are OK, but I need to reduce the current settings to get the speed?
I must be mis-interpreting this....
