Product Description:
The E31NRHT-LDNM3-00 is a Hybrid Stepper Motor manufactured by Kollmorgen>. It is part of the <
The E31NRHT-LDNM3-00 Hybrid Stepper Motor features a durable construction with a double-ended smooth shaft for enhanced encoder capabilities. It comprises four lead parallel windings with a rated current of 8.4A DC per phase. The motor attains a peak speed of 1500 RPM while retaining high torque performance. The power output is 88W, supplied by a 35V DC input and a 5.4A bipolar parallel current. It has a phase resistance of 0.13 Ohms and a phase inductance of 1.1 mH that allows for quick and precise response. The holding torque for stable positioning is 2.43 Nm. The rotor's inertia for responsive motion transitions is 0.0586 kg-m² x 10^-3. It has a typical round frame and is splashproof. A PG11 metric conduit connector is needed to connect it. When fixed, it has a thermal resistance of 3.9°C/Watt and can withstand temperature rise of up to 90°C. The motor is powerful due to its three rotor stacks. The shaft is compatible with BEI encoder mounting.
The Kollmorgen E31NRHT-LDNM3-00 has insulation class B which ensures safety. With a radial force capacity of 35 pounds and an axial force capacity of 180 pounds it can withstand heavy shaft loads. The NEMA mounting twin shaft make it simple to integrate into a system. This is ideal for industrial applications that require precise positioning, consistent speed, and reliable torque.
Frequently Asked Questions about E31NRHT-LDNM3-00:
Q: Why is the E31NRHT-LDNM3-00 designed with a double-ended smooth shaft?
A: The smooth, double-ended shaft allows for flexible encoder or gear mounting on either side. This supports advanced feedback control in bidirectional systems.
Q: What is the benefit of using a microstep controller with E31NRHT-LDNM3-00?
A: Microstep controllers enhance smoothness and resolution, minimizing vibration and resonance. This results in quieter operation and finer positioning accuracy.
Q: How does the 3 rotor stack configuration affect the E31NRHT-LDNM3-00?
A: The 3-stack rotor increases magnetic interaction, boosting torque without increasing motor size. This makes the motor more compact and power-dense.
Q: Why is a thermal resistance of 3.9°C/Watt important in the E31NRHT-LDNM3-00?
A: Lower thermal resistance ensures efficient heat dissipation, reducing the risk of thermal overload. It allows sustained high-power operation with better temperature control.
Q: How does the low phase inductance of 1.1 mH benefit the E31NRHT-LDNM3-00?
A: Low inductance enables rapid current changes, allowing quicker torque adjustments. This enhances the motor’s responsiveness in high-performance applications.
