Product Description:
The Pacific Scientific’s R45GENA-R2-M2-NV-00 is a super brushless servo motor from R series. It is assembled in a square shaped frame with 4.25 inches width and height. This motor offers high turn effect to inertia ratio, as it utilizes rare quality cobalt magnets inside the enclosure and it produces a stationary torque of 48 lb-in along with a peak torque of 200 lb-in.
The R45GENA-R2-M2-NV-00 motor is accompanied by a primary feedback system, which provides accurate angular feedback in most control systems by employing a frameless resolver that is of transmitter type and its size is 21. The motor has no shaft seal to spin frictionless at high-speed speeds with a frictional value of 0.33 lb-in and it has a back emf constant of 96 V/Krpm. Its turning effect constant is 8.1 lb-in for every ampere of current used. The stall current of the motor is 6.7 A and its peak current is 53 A, this helps in handling high loads efficiently. The R45GENA motor possess a thermal resistance of 0.61 °C/W and 29 min of thermal time constant so that it does not overheat in extreme conditions. The motor has got a weight of about 20 lbs and it comes enclosed in a tough IP65, TENV waterproof build that is resistant to severe conditions.
The R45GENA-R2-M2-NV-00 motor supports a 72 lb-in of holding brake that operates on 100 or 24 VDC and draws 0.22 A of current while possess an inertia of 0.0005 lb·in·sec². It features MS terminal connector for electrical wiring and comes equipped with long lasting greased bearing that are front locked. The R45GENA motor has total length of 9.9 inches and it is presented with a 2 inches long shaft.
Frequently Asked Questions about R45GENA-R2-M2-NV-00:
Q: Why does the R45GENA-R2-M2-NV-00 motor use a frameless resolver instead of an encoder?
A: A frameless resolver is highly durable and resistant to vibration and temperature changes, offering reliable performance in harsh industrial environments.
Q: How does the IP65 TENV enclosure of the R45GENA motor benefit its operation?
A: This enclosure protects against dust and water jets, making it ideal for outdoor or washdown environments without needing additional housing.
Q: What is the purpose of the 0.61 °C/Watt thermal resistance in the R45GENA-R2-M2-NV-00 motor?
A: It allows for effective heat dissipation, minimizing the risk of thermal overload during prolonged high-load operation.
Q: How does the 0.33 lb-in frictional value support high-speed performance in this motor?
A: Low internal friction reduces mechanical losses and enhances overall efficiency, especially when operating at maximum RPM.
Q: What advantage does the 8.1 lb-in/A torque constant provide in the R45GENA-R2-M2-NV-00?
A: It enables high torque generation with minimal current, improving power efficiency and reducing strain on the drive electronics.
