Brushless Servo Motors


Servomotori Brushless - DT / DP
SVTM D Series


DC Torque Motors operate on the same principles as the conventional DC motors but the magnetic circuit design and consequent mechanical configuration are designed for a maximum torque output rather than the usual low torque / high speed characteristic. 

A range of unhoused units are supplied as three separate components, a permanent magnet field assembly, a wound armature with precision bore for mounting and a brush ring assembly or brush segments.

A fixed element - the stator, is equipped with rare earth permanent magnets and the rotor is equipped with a dc specific winding which is connected to an extra flat commutator - brushed system.  Low speed Torque Motors are beneficial for direct-drive applications. Position and speed feedback can be achieved via additions of DC Tachos, Resolvers or Optical Encoders.

The unhoused motors described below can be supplied in custom designed housings for specific applications.
