Product Description:

The PMB31D-10100-02 servo motor functions by continuously tracking shaft position for providing speed and direction control during operation. It is a product of Pacific Scientific and the organization has a high focus on creating innovative parts that work throughout the industrial automation domains.

The PMB31D-10100-02 servo motor is installed with flying category of leads that are terminated with AMP connectors where compatibility and cable routing are critical. The sensing system will be based upon a resolver a passive feedback device that will operate on an inductive coupled scheme. Its analog characteristics make it easy to track the position continuously even against harsh electrical conditions. It is constructed to have a factory-mounted PTC thermistor for shifting resistor used with temperature which aids the winding protection as it indicates the over-temperature conditions to external controls. This frame is of NEMA 34 type size according to the mounting and flange dimensions of the unit. The stack design is of a scalable multiple length. A major electrical current of 5.4 Amp for winding capacity helps in demonstrating the current level during a nominal operating range balanced by the thermal characteristics.

The PMB31D-10100-02 servo motor supports smoother alignment of the couplings in a shaft and keeps the friction at a low level. It has universal mounting as there are no specific or keyed interfaces. There is a predetermined factory of 0 which can be connected to internal locations of identification of set-ups needed for production uniformity. It holds a UL marking as a way to confirm compliance with the accepted certifications of safety and emission protection practices that further enhance the reliability of this unit.

Frequently Asked Questions about PMB31D-10100-02:

Q: What sensor technology is used in the PMB31D-10100-02 for positional feedback?

A: The PMB31D-10100-02 uses a resolver, providing continuous analog position data, suitable for environments with high electrical noise and temperature fluctuations.

Q: Why is the PMB31D-10100-02 equipped with a PTC thermistor?

A: The PTC thermistor inside the motor monitors winding temperature and increases resistance when overheating is detected, triggering thermal protection in connected drives.

Q: What does the stack length multiple in PMB31D-10100-02 signify?

A: It represents modularity in rotor and stator design, allowing scalable torque outputs by adjusting the lamination layers without changing housing dimensions.

Q: What is the preassigned factory value 0 in PMB31D-10100-02 used for?

A: It typically denotes a baseline motor configuration, aiding in part identification, inventory, or specific internal production settings.

Q: How do flying leads in PMB31D-10100-02 improve installation?

A: The use of flying leads with AMP connectors reduces installation time and simplifies wiring in complex or confined panel layouts.
