I am getting a 300kg-cm geared stepper motor NEMA34 at the same cost of a 300kgm-cm non geared stepper motor in NEMA42. I don't have the full spec of the 300kg-cm geared motor I mean the currrent rating but the NEMA42 one is an 8A motor.
My target rpm is around 10 to 20 rpm, the geared stepper has a gear ratio of 30:1.
Suprisingly there is not much difference in price between the 2 motors.
What would be the advantage of the geared motor vs the non-geared one?
Is the torque figures indicated are holding torque values. What is the % of holding torque that is generated by the motor when the motor is running? I believe it would be lower that the 300kg-cm value.
Thanks in advance
