Product Description:
As a brushless servomotor from the PMB series, the Pacific Scientific PMB31D-20116-03 enables precise motion control and dependable operation in motion-intensive applications.
Built in accordance with NEMA Standard 34, this motor offers a small yet capable design that can be effortlessly incorporated into a variety of automation systems. Since flying leads are electrical connectors, they offer safe connections and facilitate installation in difficult settings. The motor uses a digital encoder and has commutation and providing a 4096 steps per revolution resolution to provide very precise feedback to control position and speed. Using a stack length of several times 1, this design provides a low-volume solution without compromising necessary torque response. PMB31D-20116-03 motor is nominally stalled at 240 VAC and has a nominal stall current of 5.4 ARMS. It provides a sustained stall torque of 2.11 Nm, which is suitable in applications that need good torque at a constant load. When continuously operated, its rated torque is 1.6 Nm, thus suitable for constant load applications.
In dynamic requirements, the motor is capable of a peak torque of 6.26 Nm and has sufficient spare capacity to accelerate and meet load change variability. Another advantage of this model is its performance speed. It is a strong choice for high-speed motion systems since it can achieve a no-load speed of 8400 rpm and be rated to 6000 rpm at 240 VAC. Approximately 0.14 × 10⁻³ kg·m², the rotor's inertia may be regulated steadily and respond quickly. Other features, such as maximum static friction of 0.09 Nm and a viscous damping coefficient of 0.0124 Nm/kRPM, are features that help identify a smooth and predictable performance. The thermal resistance is rated at 1.08 °C/W, which is useful in controlling heat when operating over long periods.
