They have a gear ratio of 1500:1 and operate up to 12 volts and deliver a stall torque of 1497 oz-in. and a max speed of 2 RPM. Each standard gearmotor sports a 6mm diameter D-shaft.

On any motor/gearhead unit, the motor should stall before it causes any damage to the gears. I’ve bought 4 of these and every single one of them has broken its own 30:10 internal gear. Of course you can’t buy the tiny, cheap, little gear, so you have to spend another $25 on a whole new motor. These motors need a warning : APPROACHING STALL WILL BREAK THE GEARS, DON’T EXPECT TO GET MAX TORQUE. I wish I could get my money back and put it towards a real gearmotor that meets the advertised specs. Look for a motor that stalls, not shatters. Also, this products does not have “full metal gears” as advertised; open up the gear head and you’ll find a plastic gear in there!
Sorry to hear that. I would suggest contacting our tech support team about this.
