Product Description:

The F46GENA-R2-NS-NV-00 brushless servo motor is manufactured by Pacific Scientific as a member of the F Servomotors series. Designed for commanded motion in automated assembly lines, packaging equipment, and material handling stages, the unit converts controlled stator currents into precise rotary movement. Its brushless topology reduces maintenance and allows the motor to deliver repeatable performance during high-cycle positioning, speed regulation, and rapid directional changes typical of modern CNC and robotics stations.

It develops a continuous stall torque of 61 lb-in, giving it the ability to hold loads at zero speed without thermal overload, and can supply up to 155 lb-in during short acceleration bursts. The motor has a torque constant of 11.0 lb-in/A, so drive amplifiers can estimate output from phase current. It also has a voltage constant of 130 V/Krpm, which indicates back EMF at operating speed. The square frame is 4.25 inches wide, and the assembled motor weighs 27.4 lb. These values affect mounting space, support requirements, and inertia matching in motion systems.

The aluminum housing carries a protection rating of IP65, blocking dust ingress and guarding internal components against low-pressure water jets. Because the configuration is supplied with no brake, any static holding requirement must be met by external clamps or by the drive’s torque-holding mode. Magnetic excitation is provided by ferrite magnets, and the stack length code 6 produces the listed torque within the given frame size. English mounting and shaft dimensions simplify integration with legacy couplings. The standard build omits a shaft seal for lower friction, and the absence of secondary feedback channels places position sensing solely on the primary resolver or encoder selected by the user.
