Thanks for reading and your time. The best answers are voted up and rise to the top, Not the answer you're looking for? If a voltage is applied to the motor (RL filter), the current increases with a time constant tau that is equal to L / R. In the case of PWM control, when the switch is closed, the current flowing through the motor increases and decreases during the time the switch is off. Motors with higher power have a higher inductance and thus a higher time constant than smaller motors. I apply a small amount to the pin and then tin and connect it to the wire. It's probably not what's causing your current issues, but it's a terrible idea. The choice of mode depends on the requirements of the system - if we need a large torque, the best choice is Full Step, if a lower torque is enough and maybe we power our circuit from the battery, wave drive mode is preffered. PWM is applied to a specific switch and turns the motor on and off. Always use them only in a ventilated room.
