R22HENA-R1-NS-NV-01 Image 1


The R22HENA-R1-NS-NV-01 is a high-performance servo motor in the R Motor Series by Pacific Scientific. This brushless motor boasts unique features such as anti-cog design and compact size, making it perfect for high acceleration and torque control applications. Outfitted to function reliably even under stringent conditions, it is virtually maintenance-free. Part of the distinguished R series, the motor benefits from the series' identified magnet type, rare-earth samarium-cobalt, ensuring a superior torque-to-inertia ratio while guarding against demagnetization. With an Outside Diameter (OD) and magnet length of 2 inches each, the code 'R22' signifies these two dimensions. Additionally, 'H' signifies the motor’s windings code and 'E' indicates that the motor’s shaft and mounting conform to English standards. The term 'NA' is factory preassigned. This mechanical marvel beautifully mirrors Pacific Scientific’s commitment to quality and innovation. The primary feedback mechanism of this motor is denoted by 'R1', indicating a frameless resolver, transmitter type, size 15. 'NS' suggests the absence of secondary feedback. The detail 'NV' illustrates that the R22HENA-R1-NS-NV-01 lacks shaft sealing, offering a unique selling proposition. Lastly, the '01' in the code implies that the motor comes with standard freestanding MS connectors on the end of the 18-inch leads.
