N-4220-2-K00AA

The N-4220-2-K00AA is a brushless servo motor from Rockwell Automation/Allen-Bradley. The motor has a size 42 NEMA frame, a torque rating of 20 pounds on an inch and a 230 Volts designator. The N-4220-2-K00AA has a 5000 encoder line count and a standard flange. The MPN-4220-N motor can be used to replace the N-4220-2-K00AA servo motor. The N-4220-2-K00AA, as with other N-4220 series servo motors, has a 0.00035 kg-m2 rotor moment of inertia, a 0.19 N-m per krpm damping rate, and a maximum rated operating speed of 5000 revolutions per minute.

The N-4220-2-K00AA has 4 poles, and a phase-to-phase winding resistance of 0.77 ohms at 25 degrees Celsius. The phase-to-phase winding inductance rating for the N-4220-2-K00AA is 2.9 millihenrys. The motor has power leads to a ground dielectric rating of 1800 Volts AC RMS for 1 minute at a frequency range of between 50 and 60 hertz. The shaft for the N-4220-2-K00AA is made from 416 stainless steel. The motor operates best in an environment with a relative humidity ranging between 5 and 95% without condensation. The minimum and maximum storage temperature range for the N-4220-2-K00AA is 0 and 50 degrees Celsius.

When user-built cables are used to connect the N-4220-2-K00AA with the power and feedback modules, the 2090-NPC-S (straight power connector kit) and the 2090-NFC-S (straight feedback connector kit) should be used. Note that the external surfaces of the N-4220-2-K00AA are capable of reaching a temperature of 100 degrees Celsius when the motor is in operation. Therefore, the operating environments should be ventilated and the mating connections should use cables that can withstand such a high temperature. The N-4220-2-K00AA motor should be mounted with connections pointing downwards.
