what to choose from the 2 steppers
I'm starting to build a 6x12 cnc for woodcarving
I oscillate between 2 stepper motors with similar characteristics
motor A B
holding torque 8.5 8.5
detent torque 12.5 12.5
resistance 0.56 0.5
current/phase 4.2 6
step angle 1.8 1.8
inductance 3 2.1
rotor inertia 2700 1800
lead wire numbers 8 4
I know that a stepper with lower inductance is preferable in order to be supercharged, but also the option of having 8 wires with the possibility of connecting the motor in parallel bipolar mode attracts me. which is which?
what would you choose?
Re: what to choose from the 2 steppers
You can use the first motor if your power supply is providing over 50v and your drivers can handle it. But these aren't the only motors in the world; if you want a stepper with 8 wires and lower inductance, keep looking.
