Product Description:

The R67AMNH-R2-NS-NV-00 comes from the industrial module manufacturers Pacific Scientific. It is designed with industrial automation in mind and what that entails - high speed, high torque, and efficiency. The Pacific Scientific R67AMNH-R2-NS-NV-00 motor has a stall torque (continuous) of 168 lb-in (19 Nm), a max torque of 555 lb-in (63 Nm) & can “guarantee reliable performance” for high-load motion control task automation.

It is designed weighing 49 lbs (22 kg) and with a thermal resistance of 0.3° C/W (Watt) and a time constant of 72 minutes, the heatsink maintains system reliability by getting rid of heat allowing for better prolonged operational stability. The voltage constant of 164 V/Krpm (1.56 V/rad/sec) allows for efficient power conversion and the precise control makes its continuous stall current of 13.8 A competitive. Its low inertia (0.015 lb-in-sec² / 1.69 kgm² x 10⁻³) enables rapid acceleration and deceleration of any specific motion, allowing it to specialize in dynamic control applications.

As this servomotor is the automation grade four, its robustness allows it to “expose” itself to harsh industrial environments - it matches the NEMA MG1-1.26, Part E, IP65 (excluding the shaft) waterproofing standard which guards against dust and low pressure water jets. An optional shaft seal enhances the sealing integrity but must be periodically lubricated to guarantee long term performance. For applications in need of static holding, an optional holding brake is available on the Pacific Scientific R67AMNH-R2-NS-NV-00 motor providing 180 lb-in (20.3 Nm) of static torque, at 100 Volts or 24 Volts DC (Direct Current).
