Pacific Scientific has been in the business of meeting its customers' needs through manufacturing high-quality products in pursuit of automation and intelligence solutions. Their products are not only efficient and powerful but also durable and cost-effective. The P22NRXA-LNN-NS-00 motor is one of those products and it is economical, has high performance with improved heat dissipation. We elaborate on the technical details of this motor to ensure that you can maximum benefit as you install and operate it.
The P22NRXA-LNN-NS-00 is a step motor with double rotor stacks that have standard and low inertia rotors. The low inertia produces high acceleration rates compared to the standard one. The rotor inertia for the P22NRXA-LNN-NS-00 motors is about 0.025 to 0.0036 kgm 2 X 10 -3. The estimated weight of this step motor is 1.13kg to 2.5kg and it also contains a series arrangement.
The detent torque of P22NRXA-LNN-NS-00 step motors stands at 0.049 Nm to 7Nm while the holding torque is 1.39 Nm to 197Nm. Further, the motor is operated at a rated current of 6.5A and exceeding this limit will result in demagnetization which can halt operation. Thus, you should strive to maintain that rated current at all times. The estimated value of the phase resistance is 0.21 Ω and the thermal resistance is 4.5°C/watt. Normally, this thermal resistance value is measured when P22NRXA-LNN-NS-00 is at a standstill and not yet mounted.
Finally, the phase inductance of P22NRXA-LNN-NS-00 motors’ is 0.4 mH. When measuring the motor’s signal inductance, a 1 kHz, 1A Impedance Bridge is used. When the rated current is used, with the step motor in still air, the temperature is 40 degrees Celsius without the use of heat sink while in windings it is 130 degrees Celsius.
