Product Description:
The R46GEAH-R2-NS-NV-00 is a servo motor manufactured by Pacific Scientific within the R Servomotors series. It is intended for closed-loop motion axes in industrial automation lines where repeatable positioning and moderate continuous torque are required. When paired with a servo drive, the motor converts commanded current into mechanical rotation that can be synchronized with encoders, sensors, or PLC timing signals, allowing machinery to follow velocity and torque profiles with minimal overshoot.
This model delivers a continuous stall torque of 7.6 Nm, so it can hold that load continuously without exceeding its thermal limits. Its peak torque reaches 20.2 Nm for short acceleration bursts. Rotor inertia is 0.40 kg·m² × 10⁻³, which supports fast speed changes without causing control-loop instability. The motor housing uses a compact 4.25-inch square frame, allowing it to fit equipment designed around NEMA-style footprints. A 24 V DC brake is integrated for static load holding when power is removed, avoiding the need for external clamping devices. Torque density is supported by samarium-cobalt rare-earth magnets, which maintain magnetic performance at elevated temperatures.
The motor uses inch-based mounting dimensions, simplifying alignment with inch-based gearboxes or couplings. The magnetic core extends for 6 inches, adding active length for energy conversion without increasing frame width. The motor has no shaft seal, so the coupling end must be protected from liquids or fine dust when those conditions are present. Position feedback is supplied by a frameless resolver of transmitter type, size 21. This analog device sends rotor-angle information to the drive for commutation, and there is no secondary feedback channel. The windings follow the standard thermal class pattern used across this series.
