Product Description:

The SRF5570-4483-84-82BC is a model manufactured by Pacific Scientific and assigned to the Permanent Magnet DC Motors series. Within industrial automation, the unit converts direct-current power into rotational motion that can be regulated by a closed-loop speed controller. Because its magnetic field is produced by permanent magnets rather than a wound field, no external excitation is required, simplifying wiring and reducing heat generation during continuous service. This arrangement supports stable operation in machinery that needs straightforward DC motor control and predictable speed response.

Electrically, the motor is rated for 180 VDC, a common supply level for SCR drives used in plant power systems. Its SCR-rated control designation indicates that the armature can be fed directly from a silicon-controlled rectifier converter without additional filtering, allowing straightforward speed modulation. At the rated terminal voltage, the machine delivers 3 HP of mechanical output and reaches a nominal shaft speed of 1750 rpm, a combination that suits medium-torque material-handling applications. As a permanent magnet DC motor, torque remains proportional to armature current, which helps the drive maintain a linear response as load demand changes. It is intended for Continuous duty, meaning the winding temperature rise is suitable for indefinite operation under full load without exceeding insulation limits.

Mechanical and mounting features align the motor with common NEMA installations. The totally enclosed fan-cooled enclosure is identified as TEFC, keeping airborne contaminants away from the windings while a shaft-mounted fan forces cooling air across the frame. Housing dimensions correspond to the 182TC frame code, so bolt circle and shaft height match standard reducers and pumps. For installation, a NEMA C Face flange is provided, allowing direct coupling without alignment brackets, and a Removable Base gives the option of either foot or face mounting depending on machine layout. This mounting arrangement supports compact machine assemblies where direct coupling and flexible placement are both important.
