Two stepper motors: RHT23-260 and FL57STH76. Both NEMA23 both rated at 260 oz/in holding torque. Both physically the same dimensions or therabouts.

The RHT23-260 is 3.2V @ 2.8A/phase and inductance 3.6mH
The FL57STH76 is 4V @ 2A/phase and inductance 6.4mH.

Can anyone compare and contrast these for me please?
