Product Description:

The R24HENA-HS-EB-NV-00 is a servo motor built by Pacific Scientific within the R Servomotors series. Designed for closed-loop industrial axes, it converts drive current into regulated rotary motion for pick-and-place heads, indexing tables, and other automated stations. Its round 2-inch frame and rare-earth magnetic circuit keep the package compact for dense machine layouts, making it suitable for machines where installation space is limited. The motor is intended for responsive motion control, so it fits applications that need steady speed regulation and accurate incremental movement through the connected drive system.

During continuous duty, the motor sustains a stall torque of 1.1 Nm, so it can hold or move moderate loads without overheating at rated current. When rapid acceleration is required, the electromagnetic stack supplies a peak output of 3.07 Nm for short intervals, giving added margin for brief load changes. The rotor can spin up to 7700 rpm, which supports high-speed indexing and other fast-cycle tasks. The motor has an overall diameter of 2.0" OD (round), helping it fit into compact machine envelopes without wasting mounting space. A reflected inertia of 0.021×10⁻³ kg·m² keeps the rotor response quick and helps the amplifier maintain tight velocity control during changing load conditions.

The magnetic circuit uses rare-earth samarium-cobalt magnets, which provide strong flux in a compact motor package. A laminated stack length of 4 inches works with the motor’s high-speed winding to support fast electrical response while controlling thermal rise during operation. Assembly uses English mounting hardware, allowing direct compatibility with imperial-dimensioned couplings and gearboxes. The motor is supplied without a factory-installed holding brake or shaft seal, so load holding and contamination protection must be handled by the surrounding machine when needed. Hall sensors provide the primary feedback for commutation and low-speed position tracking, which supports stable operation during startup and controlled motion at low shaft speed.
