Product Description:
The R24HENT-TS-EC-NV-00 is a brushless servo motor produced by Pacific Scientific within the R Servomotors series. In motion-control assemblies, it converts commanded electric current into rotational motion for indexing tables, pick-and-place heads, and other precision axes. When paired with a compatible drive, the motor supplies rapid acceleration, repeatable velocity, and accurate positioning for automated manufacturing cells and semiconductor tools. The servo motor is designed for closed-loop operation, allowing the connected drive to regulate its torque, speed, and position in response to feedback signals.
It delivers a continuous stall torque of 1.1 Nm, which is the steady output it can hold indefinitely without exceeding thermal limits. During rapid acceleration, the electromagnetic structure supports a peak torque of 3.07 Nm, allowing short bursts of additional force to overcome load inertia. The rotor has a reflected inertia of 0.021 kg·m² × 10⁻³; this low value reduces settling time and simplifies servo tuning. A high-speed winding lowers back EMF so the drive can sustain higher current at elevated rotational speeds. Torque density is enhanced through the use of rare-earth samarium-cobalt magnets, whose high coercivity helps maintain magnetic flux at elevated temperatures.
The mechanical envelope has a round frame with a 2.0-inch outer diameter and a stack length of 4 inches, providing a compact profile for inch-pattern mounting arrangements. The nominal operating speed reaches 7700 rpm, supporting high-throughput motion in pick-and-place and spindle applications. Rotor position and speed feedback are generated by a Tachsyn transducer, which provides tachometer and resolver signals to compatible legacy amplifiers. The motor is supplied without an internal holding brake, so the drive or an external clamp must retain static loads when the axis is stopped. No shaft seal is fitted, so the installation area should remain free of fluid spray and abrasive dust that could reach the shaft opening or bearings.
