Product Description:

Pacific Scientific manufactures the P22NRXE-LNN-NS-00 Stepper motor, which is designed for high-performance industrial automation applications. It is known for consistently putting out torque and using energy efficiently. It also has exact control for tough jobs. Positioning systems and motion control are two examples of uses that need this motor to work consistently.

The P22NRXE-LNN-NS-00 stepper motor has a steady torque of about 1.39 Nm (197 oz-in), which means it will work reliably even in tough situations. It has a rated current of 6.5A when wired in parallel and 3.3A when wired in series, which means that the motor can be used in a number of different setups. It's possible to control how much power is lost because the phase resistance is 0.21Ω in parallel and 0.84Ω in series. 0.8 mH of inductance in series and 3.2 mH of inductance in parallel help the motor work well while losing as little power as possible. Also, the thermal resistance of 4.5°C/W shows that the motor can effectively remove heat during operation, which keeps it from getting too hot and extends its life.

With a rotor inertia of 0.0036 kgm², the P22NRXE-LNN-NS-00 stepper motor is designed to move quickly and precisely when turning. The motor can quickly speed up and slow down while staying under control, thanks to the rotor's friction. Because of these specs, the motor can be used for precise tasks in areas like robotics and automated machines. This stepper motor's design makes sure that it works reliably and consistently, which is especially important in systems where precise placement is needed. The motor is built so that it always gives the same amount of power at all speeds.

Frequently Asked Questions about P22NRXE-LNN-NS-00:

Q: Why is holding torque important in P22NRXE-LNN-NS-00?

A: The holding torque of 1.39 Nm ensures the motor maintains its position under load. This prevents unwanted movement during operation.

Q: Does P22NRXE-LNN-NS-00 use parallel or series wiring?

A: P22NRXE-LNN-NS-00 can be wired both in parallel and series. It provides flexibility depending on the application’s current requirements.

Q: Do phase resistance values affect motor efficiency in P22NRXE-LNN-NS-00?

A: Yes, the phase resistance of 0.21Ω (parallel) minimizes energy loss. This improves the overall efficiency of the motor system.

Q: How does P22NRXE-LNN-NS-00 manage heat dissipation?

A: With a thermal resistance of 4.5°C/W, the motor effectively manages heat. This keeps the motor running efficiently under load.

Q: Why is rotor inertia low in P22NRXE-LNN-NS-00?

A: The low rotor inertia (0.0036 kgm²) allows for rapid acceleration and deceleration. This enhances the motor’s precision and control.
