Product Description:

The N31HRHL-LNK-NS-00 Stepper Motor is manufactured with rugged construction and optimized magnetic technology. This stepper motor delivers high torque and efficiency. It features NEMA compliant mounting for seamless integration with various mechanical systems.

The Pacific Scientific N31HRHL-LNK-NS-00 stepper motor is equipped with an IP44 protection rating that makes it resistant to dust and splashes. Its optimized housing design enhances cooling that allows for reliable thermal performance even in continuous operation. This motor can be configured with customized shaft and flange designs based on application specific requirements. This stepper motor delivers a holding torque of 4.6 Nm when each winding is activated. This motor features winding resistance at 0.36 ohms which lowers power loss and improves system efficiency. This motor maintains stable position during shutdowns thanks to its 0.13 Nm detent torque capability. It provides smooth performance with minimized electrical noise with an inductance per winding of 1.4 mH. Its large diameter rotor is designed for optimized torque output and acceleration. This ensures high performance motion control. The use of rare earth magnets provides superior demagnetization resistance. The long life steel bearing bore in the front bell enhances durability and enables the motor to withstand high radial and axial forces.

The N31HRHL-LNK-NS-00 stepper motor’s oversized long life bearings further contribute to mechanical stability that reduces wear and tear in continuous operation. This motor is available with an optional integrated encoder. This improves positional accuracy and feedback capabilities. Standard electrical connections include 300 mm flying leads with optional terminal box or connector configurations available for custom setups. This 2.3 kg weight stepper motor offers high performance in a minimal space package. The improved magnetic structure of this motor helps increase torque performance.
