The 1326AB-C4B21 is an Allen-Bradley servo motor that comes with a maximum operating speed of 1600 RPM which is also the 1326AB-C4B21’s rated speed. The 1326AB-C4B21 has a frame diameter of 194 millimeters and the motor rated output is 5.6 Kilowatts. The 1326AB-C4B21 comes with an IEC metric flange with a keyway as part of the flange and shaft series. In addition, the 1326AB-C4B21’s system continuous torque is 47.4 N-m while the system peak stall torque for the 1326AB-C4B21 being 94.8 N-m. The 1326AB-C4B21 features special flux profile permanent magnets that serve to increase the motor’s servo response. In addition, it has a 3-phase sinusoidal-wound stator that allows the 1326AB-C4B21 to operate smoothly and at low speeds. The 1326AB-C4B21 also comes in an extruded aluminum housing that allows for the improved release of excess heat.
The 1326AB-C4B21 allows the users to have flexibility when it comes to mounting the motor. This is because the 1326AB-C4B21 can be mounted vertically or horizontally. When mounted vertically, the shaft can face up or down. Another important feature that it comes with is a normally-closed thermal switch that comes in the motor winding. This provides for the thermal overload indication. The 1326AB-C4B21 is a rugged brushless resolver offering an accurate position, and it eliminates any need for onboard electronics. Further, the 1326AB-C4B21 can withstand harsh shocks and it can cope with high operating temperatures and high rates of vibration. The 1326AB-C4B21 comes with an internal holding brake. The disc type is spring set whenever the power is removed. The 1326AB-C4B21 is designed so that it can hold a load at rest and at the same time offer limited braking torque which is important when there is the need for emergency stopping. Note that the brake is not intended to be used as a positioning brake. To avoid injury, ensure that the brake is not powered on.
