## Questions & Answers

**Q: Will powering this motor with a 12v 2A power supply cause damage? The motor is rated for 12v at 1.68A**
A: No. The IV relation is fixed, meaning when you apply a certain voltage, a corresponding amount of current will flow. Due to the resistances of the windings, when you apply 12 V, only 1.68 A will flow by design. If you try to force 2A, then you will need a higher voltage.

With that being said, it is better to use a stepper motor controller IC instead of driving the motor directly from the power supply.

**Q: How noisy is this motor?**
A: It has been a long time since I purchased this gear motor and put it service, but do not remember it as being at all noisy.

**Q: How much torque is necessary to backdrive this gearbox? I am looking for a backdrivable gearbox.**
A: Are you refering to the gearbox alone or the gearbox plus the motor? The gearbox will simply amplify the amount of torque: if it's a 1:100 gearbox, for backdriving, you need 100 times the torque compared to backdriving the stepper motor shaft directly. As for the actual torque in the presence of the motor, it varies depending on how much current is flowing through the motor.

As a crude estimate, even without any current flowing, it is VERY difficult for an average adult male to backdrive the shaft of the gearbox.

**Q: Is this kind of motor (with planetary gearbox) necessary for the construction of a syringe pump, or can i use just a nema 17 stepper motor?**
A: I have used the nema 17 stepper motor for making a syringe pump with no gearbox using a leadscrew just fine for up to 25mL syringes. The leadscrew provides sufficient gearing itself. There is a good open source version on university of British Columbia. Possibly a larger syringe would necessitate a gearbox
