Motor Construction and Materials
The 3RK1301-1FB00-1AA2 features a cast iron frame for maximum durability. The stator uses high-grade silicon steel laminations for reduced core losses. Copper windings provide excellent electrical conductivity and thermal performance. Consequently, this motor delivers reliable operation even under continuous heavy loads.
Electrical Characteristics and Performance
This AC motor operates on both 50 Hz and 60 Hz power systems without modifications. The 4-pole design provides a good balance between speed and torque output. Full load current at 400V measures only 1.4 amperes for energy efficiency. Therefore, this motor suits applications where power availability varies by region.
Thermal Protection and Safety
The 3RK1301-1FB00-1AA2 includes a PTC thermistor embedded in the stator windings. This sensor detects overheating before the insulation reaches dangerous temperatures. The motor connects to a thermal relay for automatic shutdown protection. Hence, the motor will not burn out due to overloading or cooling failures.
Mechanical Features and Mounting
This AC motor uses a B3 foot-mounted design for secure installation. Four mounting holes on the base attach directly to machine frames. The 19 mm output shaft includes a standard keyway for pulley or coupling attachment. A terminal box on top provides easy access for electrical connections.
Energy Storage and Components
The 3RK1301-1FB00-1AA2 contains no battery or capacitor energy storage devices. It operates as a purely inductive motor without any electronic components. The rotor uses a rugged squirrel-cage design with no brushes or slip rings. Hence, this motor requires minimal maintenance throughout its service life.
Installation and Wiring Guidelines
Mount the 3RK1301-1FB00-1AA2 on a flat, rigid surface using four M10 bolts. Connect the three-phase power wires to the terminal box U1, V1, and W1 terminals. Attach the ground wire to the dedicated PE terminal inside the box. Wire the PTC thermistor to terminals T1 and T2 for thermal monitoring. Verify the motor rotates in the correct direction before loading the shaft. Always use a properly sized motor starter with overload protection.
