Default 12 volt motors

Hi,

As a complete novice in regards to electrical matters, maybe one of you guys
can help me with a question.

I have access to a higher hp motor than needed for a particular task and am
wondering - will it draw current relative to the load on the motor or will it
always draw more than the smaller motor independant of the task asked of it?

Regards, Leigh


Depends on what 'other' motor you mean, and the job.

Why not reveal all the details, motor types (ie series, shunt,
permanent magnet types, actual rated voltages and power ratings,
rated rpms, etc) and the job?

Can we safely assume, since you say you are a neophyte, that both
are 12 volt DC motors? I don't mean to be difficult, but you have no
idea of the suppositions some amateurs make.

If they are close in size, it might not be true, but with much
larger and smaller engines, it will always be so.

A ten horse motor will always draw more than a one horse motor.

A five horse motor starting up or under a heavy load may draw more
than a ten horse motor if the ten horse moter is not loaded down
with heavy work, just idling along.
