Constant Torque 1000:1 vs. 2000:1
Constant Torque 1000:1 vs. 2000:1
(OP)
I am selecting a vector motor for an application, and one motor has a 1000:1 constant torque and the other is 2000:1. What does that ratio represent, and which one is better?

The difference represents the accuracy with which the motor is constructed, especially the laminations, air gap and bearings, plus the heat dissipation capability. By having better designs, there are less iron losses (eddy currents) and so the motor runs cooler to begin with. They they also design the heat transfer capabilities to not rely upon fans, because at those speeds you have no fans anyway. The difference between those two motors is, however, kind of like spitting hairs IMHO.

What does your application need? If your application only needs 3:1 constant torque then both motors may be overkill and overly expensive for your needs.
