Slotless brushless DC motors represent a unique and compelling subset of motors within the larger category of brushless DC motors. They are called “slotless” be-cause typical slotted brushless DC motors contain a stator core of laminated steel composed of slots separated by teeth around which copper wire is wound. The windings in slotless motors are made possible by specialized winding process technology, such as the Parallex windings offered by PITTMAN. Motors featuring these windings offer several benefits such as low cogging, low vibration and low noise enabling smooth operation, as well as reduced rotational losses enabling higher speeds with reduced heating. These characteristics are especially advantageous in applications requiring high power output in an ergonomic design, such as high-power hand-held devices like surgical tools.  |
