Product Description:

The R45HCNA-TS-LF-NV-00 is a brushless servo motor manufactured by Pacific Scientific for the R Servomotors series. As an electromechanical actuator, it links the drive electronics to the mechanical load, delivering responsive rotation for positioning tables, conveyors, and pick-and-place axes within automated cells. Designed for seamless integration into industrial motion loops, the motor converts command signals into precise angular displacement while providing real-time velocity feedback to the drive. The overall package meets common voltage-fed servo amplifier requirements found in packaging, electronic assembly, and material-handling equipment.

Its continuous stall capability of 5.7 Nm allows the shaft to hold static loads without thermal overload, and the dynamic reserve rises to 15.1 Nm for short acceleration events such as indexing or decelerating a moving mass. The compact 4.25-inch square frame fits standard machine envelopes and keeps centerline height consistent with other NEMA 4-inch motors. A rigid NEMA Face mounting flange simplifies alignment because the pilot registers the motor directly to the gearbox or adapter plate. The embedded Tachsyn resolver supplies simultaneous speed and position signals so the drive can close the control loop without external encoders. A standard cylindrical housing promotes uniform heat dissipation during rated operation.

The rotor’s inertia of 0.31 kg·m²×10⁻³ provides a balance between rapid response and stability when the motor is paired with low-mass loads. A stack length of 5 inches extends the active iron to raise power density without changing the frame outline. Torque production is enhanced by Rare earth samarium cobalt magnets that sustain flux at elevated temperatures. Because the winding is configured for high-speed operation, the motor attains higher base speeds before field weakening. The unit is supplied without a holding brake and has no shaft seal, making it suitable for installations where back-driving is prevented mechanically and the environment is already protected.
