Product Description:

The R24HENA-HS-LB-NV-00 is a servo motor manufactured by Pacific Scientific as part of the R Servomotors series. With its compact round frame and speed-focused winding, the unit converts electrical commands from a digital drive into controlled mechanical rotation in industrial automation axes such as pick-and-place actuators and light conveyor stations. The motor’s permanent-magnet rotor, electronic commutation, and integrated feedback devices permit closed-loop velocity and position regulation, and the part number identifies the mechanical, electrical, and feedback options installed at the factory.

At stall, the motor delivers a continuous torque of 1.1 Nm while remaining within its thermal limits. During rapid acceleration, the electromagnetic system can reach a peak capability of 3.07 Nm, giving short bursts of torque for indexing or rapid starts. The rotor can spin up to 7700 rpm because the stator uses a high-speed winding with low inductance, enabling quick current changes. Dynamic response is helped by the rotor’s mass moment of 0.021 × 10⁻³ kg·m², so less energy is required to change speed. The motor is supplied without a holding brake, so an external locking method or drive torque must hold the axis when power is removed.

Magnetic flux is produced by rare-earth samarium cobalt magnets, which maintain field strength at elevated temperatures and support the motor’s high-speed operation. Commutation is referenced by Hall sensors, while position feedback is supplied through a 1000 ppr line-driver encoder for the drive controller. The cylindrical housing fits the 2.0-inch outside-diameter frame, follows the English mounting interface, and uses the standard housing style. There is no shaft seal, so the motor is best suited for clean environments or for use with an external seal. A 4-inch stack length provides the active iron volume that supports the motor’s torque output.
