Product Description:
Pacific Scientific’s synchronous motors are extremely popular amongst factory owners for their high torque motors that are able to turn at slower speeds. These high torque frame size motors are increasingly used due to their cost-effective and easy to use properties. Only requiring a resistor-capacitor (RC) network to operate, Pacific Scientific motors run from a single-phase 240vAC power. Compared to other synchronous motors available in the market, Pacific Scientific promises that their motors are able to run smoother, quitter and cooler, making them much more effective to use in high-end applications. The P2 models from POWERMAX II P Series by Pacific Scientific are characterized by their NEMA 23 size and the availability of 3 stack lengths with torque ratings ranging from 0.30 to 1.51 Nm.
The P21NRXC-LDN-NS-00 is a P Series POWERMAX II Hybrid Step Motor designed by Pacific Scientific. This motor features NEMA mounting as well as an impressive size of NEMA 23. When comparing motors, holding torque and rated current is often used as a measure of merit. These two specifications reveal the maximum external torque that can be applied to a stepper motor with rated current applied as well, without causing the motor to rotate indefinitely.
Pacific Scientific’s P21NRXC-LDN-NS-00 motor can be used with a variety of drive controllers from different manufacturers as it is compatible with a broad range of voltage and current ratings. The P21NRXC-LDN-NS-00 stepper motor has a standard encoder option and regular construction, similar to many other motors from the POWERMAX II P Series. Pacific Scientific’s P21NRXC-LDN-NS-00 motor has receptacle termination and a standard rotor type. Additionally, the P21NRXC-LDN-NS-00 motor is equipped with an assigned letter winding type and a double shaft configuration.
