Product Description:
The R43GCNA-R2-NS-VS-00 is a brushless servomotor designed by Pacific Scientific as a member of the R40 series, with a 4.25" square frame design. It includes a resolver feedback system for precise control of speed and position. This motor is built to withstand harsh installation sites with its IP65 rating, as its shaft comes with an imposed Viton seal.
The R43GCNA-R2-NS-VS-00 motor features cobalt permanent magnets of stack length 3 inches for high torque and low rotor inertia of 0.00020 kg·m², to ensure rapid speeding. It provides continuous stationary rotor torque of 3.7 Nm and it can provide a peak turn effect of 15.2 Nm. The motor’s G winding offers 1.22 Nm of constant torque against the usage of every 1 A of current while it also features a high voltage constant rated at 128 V/Krpm. In stationary condition the R43GC motor draws 3.5 A of current and this current can reach up to a maximum value of 27 A in full load scenario for a short time. It stays in ambient thermal range during continuous duty operations through natural convection and radiation process, as it is accompanied by an aluminum heat sink to dissipated heat efficiently in about 19 minutes of time.
The R43GCNA-R2-NS-VS-00 motor’s thermal impedance is at 0.52 °C/Watt and it functions up to a maximum of 113°F temperature without derating. It comes with a NEMA design of shaft and mounting positioning, while it has a total length of 8.4 inches and the shaft measures 2 inches in length as well as 0.6245 inches in width. The R43GC motor does not includes a braking system and as a brakeless unit it carries a mass of 6.8 kg on its own.
Frequently Asked Questions about R43GCNA-R2-NS-VS-00:
Q: Why is a thermal impedance of 0.52 °C/Watt important for the R43GCNA-R2-NS-VS-00?
A: The low thermal impedance helps in efficient heat dissipation, preventing overheating and improving the motor's reliability during continuous duty. It is crucial for maintaining optimal performance under load.
Q: How does the Viton seal contribute to the motor's performance?
A: The Viton seal on the shaft prevents contaminants from entering, ensuring long-lasting durability in harsh environments. It allows the motor to maintain its IP65 rating.
Q: What is the significance of the resolver feedback system in the R43GCNA-R2-NS-VS-00 motor?
A: The resolver feedback system ensures precise speed and position control, enhancing overall motor accuracy. It contributes to maintaining stability during high-torque operations.
Q: What advantages does the motor’s 128 V/Krpm voltage constant offer?
A: The high voltage constant allows for better efficiency at higher speeds, ensuring the motor can perform well across a wide range of RPM. It also minimizes power loss at varying speeds.
Q: What is the significance of the aluminum heat sink in the R43GCNA-R2-NS-VS-00 motor?
A: The aluminum heat sink helps to dissipate heat efficiently, reducing the motor’s thermal load. This extends the lifespan of the motor under continuous operation by maintaining safe temperatures.
