WebSeries-wound Brushed DC (SWDC) motors have the field coil in series with the armature. These motors are ideally suited for high-torque applications because the current in both the stator and armature increases under load. A drawback to SWDC motors is that they do not have precise speed control like PMDC and SHWDC motors have. WebSep 18, 2012 · Field controlled DC motors can only operate above the normal speed. Higher speeds can also result in less torque. Reduced stability: The field control method allows operators to obtain higher speeds than the norm. Yet its overall range can be lowered due to a lack of stability.
