Focusing on brushless DC (BLDC) motors, William Huang, Senior Design Engineer at Portescap, examines six design options that can enable the designer to reduce
the overall size of the surgical hand tool without sacrificing performance.

Surgical hand tools require a minimum level of power for a given application, and higher
power requirements generally necessitate the use of larger motors, with more wires or magnets. However, this, in turn, leads to a heavier and bulkier tool
that reduces surgeon precision and increases fatigue.

Fortunately for the surgical hand tool designer, there are other options within the construction of electric motors that can
be useful in reducing the overall size and weight of the tool. Let's look at six such options in more detail...
