Product Description:

The F45HENA-R2-NS-NV-00 is a brushless servo motor produced by Pacific Scientific as part of the F Servomotors series. It serves as a torque source in automated machinery, converting controlled current from a servo amplifier into precise angular displacement for robotics, packaging stations, and general motion platforms. The unit follows the standard mechanical outline of the series, allowing direct installation on inch-based gearboxes or couplings used in production equipment.

The motor delivers a continuous stall torque of 46 lb-in, meaning it can hold this load indefinitely without overheating when the drive supplies rated current. For rapid acceleration, it reaches a peak torque of 117 lb-in, giving short-term overload capacity for starts, stops, and inertia changes. The laminated steel frame measures 4.25 inches across the mounting face, so it fits mid-frame installations while preserving space for the winding and magnetic components. With a mass of 22.0 lb, the motor remains manageable during installation and supports moderate rotor inertia for stable axis response. The motor has an IP65 rating, which keeps out dust and resists low-pressure water jets at the housing.

The magnetic circuit uses Ferrite material with a stack length of 5, supporting consistent torque production across the operating range. Because the design includes no brake, holding force must be supplied by the drive or by external mechanical hardware when the axis is powered down. The motor also has no shaft seal, so the shaft exit should be kept away from direct fluid spray. Standard internal Hall sensor feedback is provided, and no secondary feedback channel is included, which keeps cabling simple for controllers that rely on Hall-based commutation while still supporting typical closed-loop servo operation.
