Have a nice day,
Thank you in advance

a motor draws as much current as it needs.
The current is low when the motor has no load and is high when the motor starts and when it is stalled by a load that is too mnuch.

If your motor is made by a half-decent manufacturer then look at it datasheet that will tell all about it.

If the motor is a cheap one then guess its spec's. Compare its size to one that has spec's.

Get the number from the chip that drives the motor. Then google for the datasheet for the chip, it will list a spec for the coil current. That will give you a ball park figure. Generally they are a few hundred mA or less.
