Product Description:
The R24HENA-HS-NS-NV-00 is a brushless motor from Pacific Scientific's R series. It is designed for precise motion control and it operates with a nominal voltage of 240V AC along with 320V DC bus voltage. The motor features a low-inertia samarium-cobalt rotor to ensure quick response during acceleration and deceleration.
The R24HENA-HS-NS-NV-00 motor is equipped with Hall sensors for primary feedback and it offers a continuous stationary torque of 1.1 Nm along with a peak torque of 3.07 Nm. The motor has a thermal protection thermistor to prevent overheating during operation and it comes with an IP65 washdown construction to make it dust and water resistant. The R24HENA motor operates efficiently at a maximum speed of 7700 spins/min and it possess a maximum static friction of 0.04 Nm. It weighs 1.5 kg and its shaft is built to support extra configurations as per need. This motor has a viscous damping coefficient of 0.008 Nm/krpm and its thermal resistance is 1.27 degrees C/Watt. It takes 17 minutes to cool down on its own during continuous operating scenarios and the R24HENA motor is designed for high torque-to-inertia ratios without demagnetization, that provides smooth and reliable performance in dynamic applications. It is composed of 4 pole pair structure for exact synchronization and steady performance. The R24HENA motor features a class H electrical insulation to bear high internal temperatures and it possess built-in thermistors inside the winding for overheat protection.
The R24HENA-HS-NS-NV-00 motor's construction is totally enclosed, non-ventilated and it achieves cooling through natural radiation/convection process, without the need for external blower. Its moment of angular inertia is 0.000021 kgxm^2 and the winding resistance is 5.5 Ohms. The R24HENA motor comes with MS-type connectors for electrical wiring and its stator has an anti-cog design.
Frequently Asked Questions about R24HENA-HS-NS-NV-00:
Q: Why is a samarium-cobalt rotor used in the R24HENA-HS-NS-NV-00 motor?
A: Samarium-cobalt rotors provide higher thermal stability and resistance to demagnetization. This allows the motor to maintain performance under extreme operational conditions.
Q: Why are Hall sensors used in the R24HENA-HS-NS-NV-00 motor?
A: Hall sensors provide precise rotor position feedback, which is crucial for smooth commutation and accurate motion control in servo systems.
Q: What role does the anti-cog stator design play in the R24HENA motor?
A: The anti-cog design minimizes torque ripple, improving motor smoothness and enhancing positioning accuracy in precision applications like CNC machinery.
Q: How does the thermistor-based thermal protection system work?
A: Built-in thermistors detect temperature rises in the motor windings, allowing for automatic shut-off or throttle-down to prevent damage due to overheating.
Q: What applications benefit from the 0.008 Nm/krpm damping coefficient in the R24HENA-HS-NS-NV-00?
A: This damping value helps suppress mechanical resonances, improving stability in high-speed automation tasks and laser positioning systems.
