Product Description:

The R43GENA-TS-NS-VS-00 is a motor produced by Pacific Scientific within the R Servomotors series. In automated machinery, it converts regulated drive current into controlled rotary motion, allowing positioning, velocity regulation, and indexing on axes such as conveyor heads or pick-and-place joints. When integrated with a matching drive, it forms the electromechanical element that delivers commanded movement in response to process control signals. Its servo construction supports repeatable starts, stops, and reversals in coordinated motion systems.

Its continuous stall torque is 3.9 Nm, indicating the moment the shaft can hold indefinitely without thermal overload, while a peak capability of 10.4 Nm supplies short bursts for acceleration and load disturbances. The rated speed of 1500 rpm is the output velocity at nominal current, and an inertia of 0.22×10⁻³ kg·m² affects how quickly that speed can be reached or reversed. A 4.25" square frame matches common NEMA mounting footprints and fits brackets used on inch-based machines. The housing follows the standard style, the winding uses the standard temperature class, and all mechanical interfaces use the English pattern. This layout suits equipment built around inch-based hardware and standard mounting dimensions. Because it is supplied without a holding brake, vertical loads must be secured by external means when power is removed.

Flux is generated by samarium cobalt magnets that maintain high residual magnetization even at elevated temperatures. Primary motion feedback comes from a Tachsyn resolver that provides both tachometer voltage and coarse rotor position, and there is no secondary transducer fitted. A Viton shaft seal guards the bearing set against spray or dust, supporting use in washdown or particulate environments. The laminated stator uses a stack length of 3 inches to balance torque output with overall mass. This motor is suitable for medium-inertia loads in packaging, material handling, and light assembly applications.
