The short mechanical time
constant makes it ideal for control operations.
An extremely short electrical constant provides high peak
torque at high speed.
A high "theoretical" acceleration gives an extremely
fast response time.
High stall torque due to the absence of commutator bars.
Low thermal resistance provides low working temperatures.
High power to weight ratio, ideal for manipulator mounted
Air gap design, small diameter and short length.
For many applications a separate position sensor is not required,
the resolver can be used for deriving a position feed back signal
as well as speed/current information.
