Product Description:
The R46SENA-TS-ED-NV-03 Servo Motor of B & R Automation is constructed with a rare earth magnet based on samarium cobalt, which is chosen for its high retention of magnetic field strength. The use of this magnet material provides assured torque delivery over long cycles and at high operating temperatures.
This servo motor is provided to deliver a peak torque of 30.5 Nm to sustain quick acceleration and large transient loading. This servo motor offers a stall torque of 7.2 Nm continuously, which ensures output during static or slow-moving processes where dissipating heat is paramount. The 0.52 °C/Watt thermal resistance collaborates with this motor’s 35-minute thermal time constant to ensure it sustains a consistent thermal profile. The viscous damping coefficient of 0.019 Nm/Krpm helps this servo motor reduce torque ripple and maintain system response stability while performing high-speed rotation. The R46SENA-TS-ED-NV-03 motor has a shaft length of 40 mm that needs to be securely coupled and efficiently transfer torque to mechanical components that are connected to it. Its 110 mm flange size offers a firm mounting platform that adheres to industrial mechanical standards for the tight packaging of automation.
Its 11.3 kg motor-only weight contributes structural mass to minimize vibration and ensure stable positioning in fixed-position systems. This R46SENA-TS-ED-NV-03 Servo Motor,with an inertia rating of 0.38 kg·m² × 10⁻³, is specifically geared towards rapid directional changes and precise positioning tasks. This low inertia also improves responsiveness to control, particularly in applications that need to make frequent speed changes. This motor’s maximum static friction of 0.044 Nm provides a smooth start of motion and minimizes mechanical resistance when starting up. This motor’s NEMA MG1-1.26 compliant waterproofing provides a barrier from environmental contaminants like dust and water for safe running in industrial settings with risk exposure.
