I have bought 131:1 Metal Gearmotor 37Dx57L mm with 64 CPR Encoder https://www.pololu.com/catalog/product/1447.
The specification show that its stall current is 5A.
I have project to make simple scara robot that can draw a square with 2 dc motor+encoder
when the stall current happened? Is it happen every it start moving?
Do i need h-bridge that can supply 5 amps or more per motor? what product would you recomended?
The stall current will be drawn in a few cases:
- If your motor goes from rest to full speed
- If you prevent the motor from turning while fully powered
- If you reverse directions really quickly (the motor could draw twice the stall current)
We generally recommend choosing a motor driver that has a continuous current rating greater than or equal to the stall current of your motor. We have a lot of motor drivers and controllers that can drive those motors, but a specific product recommendation depends on your application. However, the only controller we carry that can handle encoder input is the Roboclaw.
