Product Description:

The JR16M4CH motor delivered by Kollmorgen has a unique internal construction and shape. This motor has an armature designed using multiple layers of copper conductors. The product is very light and small compared to a motor with an iron core. This device operates at any speed without any cogging. The unit is associated with low inertia. It features a high peak torque capability that results in high throughput. This motor depicts more moves per second.

The product portrays full torque at a high speed. This device features low inductance. The unit does not feature any cogging. Its aluminum heatsink has a size of 16 x 16 x 3/8 inches. This motor has a moment of inertia of 5.93 kgcm² for its rotor. The product also depicts a continuous stall torque of 31 lb-in. This device is associated with a large torsional stiffness for accurate speed and acceleration control. The unit can be used in combination with a KXA Plus amplifier. It has no holding brake. This motor features a very low mechanical time constant.

The product is highlighted by a circular frame with a diameter of 7.38 inches. This device is suitable for use in areas where space is a problem. The unit can be fitted with a tachometer featuring a peak-to-peak residual ripple of 4%. Its heatsink is made of aluminum. This motor has a torque constant of 37.28 N-cm/Amp with a tolerance of +/-10%. The product uses an encoder with a resolution of up to 2540 cycles per revolution for feedback. This device has 165 commutation bars. The unit has a horsepower rating of 1.39 HP. It has a high surface immediately after and during the operation period and should not be touched to avoid burns.
