Product Description:

The Pacific Scientific PMB31B-10116-03 is an ultra-efficient brushless servomotor designed to provide high-quality motion control in industrial applications. It has a NEMA Size 34 frame with flying leads and AMP connectors to connect easily. It has a digital encoder and the ability to work with fine 4096 PPR resolution to provide full positional feedback and to increase system responsiveness when operated in dynamic systems. Its compact footprint delivers excellent shock resistance, and with a stack length multiple of 1 compared to the Origin 2 family, it provides an efficient and space-optimized solution, ideal for applications requiring precise performance in tight installation areas.

One of the major advantages of this servomotor is a broad range of operational voltages, which is up to 240 V AC or 320 V DC. The wide maximum operating voltage range allows the motor to function with both AC and DC drive systems, making it highly adaptable for diverse industrial environments and varying power conditions. Its capacity to handle such voltage levels, whether incorporated into high-speed automation or precision tools, is crucial in maintaining constant torque and ensuring system stability, even when there are fluctuations in load conditions. This feature increases the flexibility of the motor and helps it to be used in various types of machines and control systems.

Moreover, the PMB31B-10116-03 features an IP40 protection rating, which safeguards it against solid objects larger than 1 mm, such as tools or small components, but offers no protection against water ingress. This level of protection may not be the right choice for a harsh or moist industrial environment, but it is an excellent choice for use in closed or curated environments such as manufacturing, 3D printing, or light assembly.
