F(H) Series Frameless

product picture

Kollmorgen F/FH (high voltage) Series Frameless Direct Drive Rotary (DDR) motors utilize a proprietary neodymium-iron magnet rotor structure and skewed armature assembly to provide excellent levels of torque/volume. The windings are encapsulated with high temperature epoxy, which provides excellent thermal properties and mechanical protection. Their high magnetic pole count design produces exceptionally low cogging for smoother low speed operation in applications such as coating and wafer handling.Learn More >
