Ironless DC Motors Deserve a Second Look Design World

May 18, 2008 · Because the weight of the ironless rotor is significantly less that the weight of a comparable rotor in a cored dc motor, ironless motors accelerate and decelerate much faster. Low-inertia motors can also present a significant advantage for applications with hard stops; the rotor is less susceptible to damage.
