Product Description:
The R63HENA-R2-NS-NV-00 is a servo motor produced by Pacific Scientific as part of the R Servomotors series. Designed for closed-loop motion systems, it supplies regulated torque and speed to packaging lines, material-handling axes, and other industrial automation equipment that needs accurate rotary positioning. The motor fits directly to gearboxes or belt pulleys and interfaces with standard drive amplifiers through its resolver signal. This feedback arrangement allows the connected drive to compare commanded and actual rotor position during dynamic motion.
At a standstill, the rotor delivers 8.3 Nm of continuous torque, letting it hold load inertia without overheating. During acceleration, it reaches 20.5 Nm, which is suitable for short-term load surges. The rotor has an inertia of 0.81 kg·m² ×10⁻³, so drive tuning can be set for fast response. A base speed of 6000 rpm is attainable because the windings minimize inductive drop at high frequency. Flux is provided by rare-earth (samarium cobalt) magnets that maintain magnetic strength at high temperature and allow a compact frame. Resolver feedback, using a frameless transmitter-type unit in size 21, supplies rotor angle information, and no secondary transducer is fitted. The motor uses the standard housing style and is supplied without a holding brake, so static locking must come from the machinery. There is no shaft seal, so the mounting zone must stay free of coolant or dust.
Mechanical integration is supported by a 5.75" square frame that shares bolt patterns with many planetary gearheads. With a stack length of 3 inches, the motor remains short enough for tight enclosures while still providing the magnetic volume needed for this output class. The shaft end and pilot conform to the English mounting code, allowing direct coupling to inch-based transmission components without adapters. A high-speed winding option is factory installed, so full rated power is available when the drive operates at higher bus voltages. This layout suits compact machine sections where rear clearance is limited and direct coupling to inch-based hardware is preferred.
