Product Description:

The R24HENA-HS-LB-NV-02 is a compact motor manufactured by Pacific Scientific for the R Servomotors series. Designed for closed-loop motion control in industrial automation, it converts electrical energy into controlled mechanical rotation that positions loads in conveyors, gantries, and lab automation stages. A standard housing and an English mounting face make it interchangeable with legacy installations. Rare-earth samarium cobalt magnets supply high flux density that supports rapid acceleration and stable operation across the speed range. This arrangement lets the motor respond quickly to repeated start-stop cycles and direction changes that are common in indexing and transfer tasks. Its compact size also helps where available mounting space is limited.

A continuous stall torque of 1.1 Nm allows the axis to hold position without overheating during static load conditions. The rotating assembly has an inertia of 0.021 × 10⁻³ kg·m², so the drive can use aggressive acceleration profiles without demanding excessive current from the amplifier. The shaft can reach a rated speed of 7700 rpm, supported by the optimized electromagnetic design and the compact 2.0-inch OD frame. Rotor position information is provided through Hall sensors, which support startup commutation and add redundancy in the feedback chain. Low inertia also helps the servo loop correct speed changes quickly when the load varies during normal machine operation.

During dynamic moves, the motor can deliver a peak torque of 3.07 Nm for short intervals, giving the machine extra force to overcome friction or accelerate payloads. Motion accuracy is refined by a secondary feedback channel that uses a 1000 ppr line-driver encoder, which supports tighter velocity regulation after startup. The laminated stack length measures 4 inches, and the electromagnetic design uses a high-speed winding that lowers inductance for quicker current rise. Using Hall feedback with the encoder gives the control system both commutation support and finer position tracking during closed-loop running. The motor is supplied without a holding brake or shaft seal, which reduces inertia while keeping the overall package compact.
