Comparing rated, stall, and inrush current in DC motor
I have a motor and it only says a rated current. Would it be safely larger than the other two?


For nearly all motors, the rated current is much less than stall/inrush current. Most motors are rated for continuous operation at rated current. A typical motor can withstand stall current for no more than a few seconds. DC motors that are rated in the kilowatt range typically can not withstand stall current at all. They must always be started using some external means of limiting the current. When such motors were widely used for industrial applications, the de facto standard for the controller short-term current rating was 150% of rated current for 1 minute.

There are motors called torque motors that are designed to operate an extended period of time at stall current.
