Product Description:
The PMB31B-20101-00 brushless motor falls under the PMB servomotor family from Pacific Scientific . It functions by converting electrical force into mechanical motion. The firm excels in industries due to its innovative parts that are widely utilized in control technology.
The PMB31B-20101-00 brushless motor works within the NEMA Size 34 frame category by ensuring a link with standard mounting systems in industrial automation platforms. It includes a stack length multiple configuration which enables it to support varied torque output based on the application. It comes with a 2.7 A winding specification by allowing it to maintain stable current levels during operation. It is equipped with a square key shaft type which is mainly applicable for sizes 2 and 3, by ensuring secure mechanical coupling in motion control assemblies. The factory default setting of this model is set at 0 meaning it is the default setting and can be set to the norm. The electrical connection is enabled with flying leads having AMP connectors which made it easier to handle the assembly.
The PMB31B-20101-00 brushless motor has an integration of a Hall sensor to convey the rotor position for the feedback and this makes it easier to smoothly control both speed and torque. The code in the customization of this unit suggests a typical configuration. This fits well in a 95 percent humidity environment and a height of installation of up to 1000 meters above the sea area. These environmental specifications are done so that the unit can be reliable in diverse working conditions in industries. The installed sensors permit the accurate positioning and add efficiency and quickness in the overall working of the unit.
