Product Description:
The R43HCNA-NP-RW-VS-00 is an R-series servomotor from Pacific Scientific. It has a fully enclosed industrial grade metal housing that has corrosion resistant finish for durability and its length is 21.3 cm. This motor includes a 0.75 inches keyed shaft with a Viton embedded seal and it is built with rare quality permanent magnets for high torque density.
The R43HCNA-NP-RW-VS-00 motor features low-inertia rotor construction to support dynamic acceleration and deacceleration. Its shaft is attached to sealed bearings that are lubricated for extended life expectancy. The motor uses a NEMA 56C face-mount flange for mechanical compatibility and its housing has IP65 environmental protection against dust and water spray. The R43HCNA motor maintains cooling through natural convection with no external fan and it incorporates insulation system of category H to withstand up to 180 degrees C temperature. A PTC thermistor is built into the windings for temperature sensing and the motor operates reliably in thermal range of 0 to 40 degrees C. The R43HCNA motor supports continuous operation up to 3280 ft altitude without derating. It has a torque constant of 0.7Nm/A and the EMF constant is rated at 45V per 1000 RPM. The stator resistance is 2.5 Ohms at 25 degrees C and its power input uses a 4-pin MS connector for three-phase supply.
The R43HCNA-NP-RW-VS-00 motor runs on a 240VAC nominal supply and it supports a DC bus voltage of 320V. Its rated continuous torque is 3.9Nm with peak torque of 10.4Nm. The motor has a rated speed of 3700RPM with a mechanical limit of 5300RPM and its power rating is 1.4kW. It draws 5.6A continuous current while the current draw reaches near 16.8A during full load. The R43HCNA motor's feedback system uses a frameless size 21 resolver that provides absolute position within one revolution and it connects via a multi-pin MS-style feedback connector.
Frequently Asked Questions about R43HCNA-NP-RW-VS-00:
Q: Why does the R43HCNA-NP-RW-VS-00 use a low-inertia rotor?
A: A low-inertia rotor enables rapid acceleration and deceleration, which is essential for high-speed, precision-controlled motion in automation systems.
Q: What is the advantage of the frameless size 21 resolver in the R43HCNA motor?
A: The frameless size 21 resolver allows for compact feedback integration and provides absolute position feedback without the need for external sensors.
Q: How does the Viton seal on the shaft benefit the R43HCNA-NP-RW-VS-00 motor?
A: The Viton seal enhances chemical and thermal resistance, protecting internal components against contaminants and extending motor life in harsh environments.
Q: Why is IP65 protection important for the R43HCNA-NP-RW-VS-00?
A: The IP65 ensures the motor is completely protected against dust and low-pressure water jets, making it ideal for factory or outdoor applications where exposure is common.
Q: What's the role of the PTC thermistor in the R43HCNA motor?
A: The PTC thermistor monitors the winding temperature in real-time and helps prevent overheating by signaling the drive to reduce or stop current if needed.
