Product Description:
Pacific scientific produces the magnetic motor R43HCNA-R2-NS-NV-00 as a part of the R40 series. It has been designed as a high torque unit to deliver 135 lb-in of peak and 33 lb-in of normal turning effect. This motor has been engineered to deliver fast acceleration and deceleration with its low inertia rating of 0.0018 lb-in.-sec².
The R43HCNA-R2-NS-NV-00 motor motor has samarium magnets to give high torque-to-inertia ratios for quick dynamic response. It works with a frameless transmitter type of resolver that serves as the main feedback mechanism to provides high accuracy in positioning and accurate control. This motor lacks a secondary feedback device and its thermal resistance is rated as 0.72°C/Watt while it possesses 1140 sec of heat dissipation constant to maintain stable operations even under continuous load conditions. Its viscous damping factor stands at 0.010 lb-in/Krpm, to ensure smooth operation at low speeds and to minimize any mechanical oscillations or vibrations. The R43 motor comes without a shaft seal that makes it only suitable for safe installation environments with a maximum operating temperature of 318.15K and humidity level between 5% to 90% RH, without moisture formation nearby. It operates with a voltage constant of 0.61 V/rad/s and features a turning effect constant of 0.61 Nm/A.
The R43HCNA-R2-NS-NV-00 motor is a compact unit with a weight of 15 lbs and measures 4.25 inches in width along with height to fit into limited space machines. Its cold resistance is 2.5 Ohms and possess 3.7 Ohms in hot conditions. It is engineered for NEMA 56C mounting to offer easy integration into industrial systems. The R43 motor has applications with axis and spindle drives in robotics and automated systems, where precise control is essential.
