Product Description:
The R43GENA-TS-M3-NV-02 is a brushless motor produced by Pacific Scientific for the R Servomotors series. Built for closed-loop positioning and velocity control, it converts electrical power from a matched drive into precise rotary motion for pick-and-place axes, indexing tables, and other automated equipment. An integrated feedback device and low-inertia rotor support consistent step-and-settle behavior in packaging lines, machine tools, and robotic fixtures that require accurate motion throughout each operating cycle.
The motor has a 4.25-inch square frame and a 3-inch active magnetic stack, allowing it to fit compactly into machines that use NEMA-like mounting footprints. Its standard housing is suitable for general-purpose enclosures, while the absence of a shaft seal simplifies installation when sealing is provided by an external coupling. The motor produces a continuous stall torque of 3.9 Nm, which it can apply continuously without exceeding its thermal limits. During short acceleration periods, the peak torque of 10.4 Nm provides additional force for changing loads. The rotor inertia of 0.22 kg·m² × 10⁻³ supports rapid changes in speed and responsive positioning. Its winding uses a standard resistance and inductance configuration for compatibility with suitable brushless motor drives.
The motor has a rated speed of 1500 rpm, keeping continuous operation within the linear back-EMF range of common brushless drives. Its rare-earth samarium-cobalt magnets provide consistent magnetic flux at elevated temperatures and reduce the risk of demagnetization during overload conditions. Position and velocity data are returned through a Tachsyn transducer, which provides tachometer output and resolver-style angular information to the controller. Mechanical attachment follows an English mounting pattern, and the motor is supplied with no brake, reducing inertia and making it suitable for systems that maintain position through drive torque or an external locking mechanism.
