So there are two things going on:
- The motor you picked has very low torque.
- The motor current is not the same as the power supply current.
Here you can see I have added (temporarily for the screenshot) your motor to the ODrive Motor Guide
As the guide will tell you, the rated torque at full current for this motor is only 30N-cm, which is not very much. If you are looking at buying a motor, you can take a copy of the guide, and enter the data for your prospective motor to see its performance. Specifically, the motor torque is proportional to
I_max / kv, and your motor has a very high kv.
Secondary, the current in the motor is not the same as the current from the power supply. In general, when the motor is stopped, the current is significantly lower on the power supply. When the motor is spinning at top speed then they approach similar values.
