Product Description:

The Kollmorgen U16M4HT motor is different from standard servomotors because of its ironless disc armature with a unique internal construction. This motor has large torsional stiffness. The product has an exceptionally compact design. This device can reach a speed of 0 RPM to 3000 RPM with just 60 degrees of rotation. The unit has no arcing because there is no iron in its armature. Its small and light aperture makes it less heavy than standard servomotors. This motor portrays a short cycle time along with more moves per second.

The product is ideal for applications that require smooth and precise speed control. This device helps in meeting the increasing demand for business automation requirements. The unit has full torque from 0 to full speed. It portrays an ultra-smooth rotation at any speed. This motor has a round frame. The product faces axial and radial phases when it is in the operation phase. This device is integrated with a tachometer to support its operation. The unit weighs 8.5 kg and is only 3.03 mm long. Its magnetic field is aligned axially and parallel to its shaft.

This motor delivers the desired torque very fast with its very low electrical time constant. The product portrays a low close physical coupling. This device depicts a long brush life because of the elimination of arcing. The unit owes its flat-disc configuration to the copper conductor layers in its armature. It is ideal for deployment in robot axis drives because of the compact size and high torque combination. This motor has its magnets positioned on the end plates resulting in an axial magnetic field and a small air gap between the magnets.
