Product Description:

The JR24M4CH motor provided by Kollmorgen has an industrial-grade housing. This motor has a flat disc armature that gives it a low profile. The product has high-grade connectors. This device incorporates a square key for its output shaft. The unit ensures high profitability and productivity in incremental motor applications. Its armature has zero cogging because of the lack of iron used in its construction. This motor has a peak current that is around 10 times its continuous current rating.

The product portrays low radio frequency interference. This device has a rated terminal voltage of 138.2 V. The unit is associated with a back EMF constant of 43 V/KPM with +/-10% tolerance. It has high torsional stiffness. This motor depicts a peak torque and current based on a 1% duty cycle and a maximum 50 ms pulse duration.

The product can perform a complete move in less than 10 ms for the entire move. This device incorporates a NEMA 182ATC face mount. The unit has a weight of 50 lbs. It produces torque when the current flow via the copper conductors interacts with the fields of its permanent magnets. This motor has an excellent torque-to-inertia ratio because of the thin design of its armature. The product has a high throughput and performs more moves per second than a standard motor. This device depicts no arcing as there is no energy to be dissipated from the armature during commutation. The unit has a constant torque up to a speed of 4000 rpm. It is ideal for applications where a low profile is required. This motor features a very low armature inductance of less than 45 µH and a viscose damping constant of 12 N-cm/KRPM.
