Product Description:

The U16M4H motor launched by Kollmorgen is a DC motor with an ironless disc armature. This motor has a lightweight armature with many copper conductor layers. The product features a minimum air gap between its magnets. This device can complete an entire move in less than 10 ms for most applications. The unit portrays a smooth torque output. It produces a magnetic field in an axial orientation. This motor is best known for its high-speed capacity.

The product poses no risk of arcing. The device features an increased throughput that makes it the right choice for applications where accuracy and performance are critical. This unit is operated in smoke generators, document readers, and biomedical equipment to mention just a few. It is easier to design than a conventional motor because of its high power output as well as flat profile. This motor makes more moves than usual as a result of its fast acceleration. The product is used in both motion-control and continuous-speed applications. This device has no commutation limits. The unit should be mounted and installed on a clean surface. Its peak current is 10 times higher than the continuous current.

This motor operation must be done only with compatible amplifiers. The product-related technical details for its service can be found on its type plate. This device may cause burns if it is touched with bare hands when its surface is hot. The unit does not come with any tachometer integrated into it. It has a continuous stall torque of 501 oz.-in. This motor has high torsional stiffness and zero cogging a low inertia for its armature to deliver high performance combined with high productivity at the same time.
