Product Description:

The N12M4 motor by Kollmorgen incorporates neodymium magnet technology. This motor is characterized by low RFI and zero cogging. The product is enclosed in a round frame. This device has a peak torque of 1128 N-cm. The unit delivers full torque at a speed ranging from 0 to 4000 RPM. Its large torsional stiffness results in enhanced performance. This motor has no commutation limits because of speed as there is no arcing.

The product portrays a small air gap that is separated by the thickness of its armature. This device performs one complete move in less than 10 milliseconds when it is deployed for some applications. The unit has smooth rotation at any speed because there is no cogging. Its peak current is rated for ten times the continuous current rating. This motor can be deployed in various industrial sectors. The product surface tends to become very hot when it is operated. This device is characterized by accurate tracking and fast moves because it produces full torque almost as soon as it is started. The unit performs rapid acceleration and deceleration. Its high responsiveness makes it a preferred choice for process control applications.

This motor can make several moves in a span of one second. The product has made a name for itself in various medical life-support applications. This device has several advantages such as long life, excellent accuracy, increased throughput, and enhanced packaging. The unit can be used for handling continuous materials because of its high smoothness. Its armature is supported by a flat disc. This motor is distinguished from standard servomotors by its ultrathin compact size and is designed to support operation at up to 6000 RPM speed.
