You create a magical motor at least as large as your palm, and no larger than 3 feet in any dimention. This motor has a maximum horsepower that is a percentage of the gp cost you put into it, with a 100gp motor having 22 horsepower and a 1gp motor having only 0.22 horsepower. Instead of a single motor, you can create as many as you have the materials for, following the same 1gp minimum cost and horsepower limits for each one. As a action, you can touch the motor and command it to turn at watever speed and horsepower you wish up to the maximum for the engine. If Dispell Magic is cast on the motor, it no longer functions, but can be used as the material for this spell. This spell is a vital part of any automatons you may create, and is technically cast when you create them, except without material costs.
(If you are a Artificer with a Homunculus servant or the Battle Smith subclass, you learn this spell for free when you choose those options.)
* - (several sheets of metal, magnets, and dragonshards (Materials must cost a minimum of 1gp, and cost no more than 100gp))
