Motor Armature/Rotor - Ametek Lamb 116311-01 Motor P2500 The kit connects to theThis replacement motor armature, or rotor, restores drive to the Ametek Lamb 116311 01 vacuum motor. The armature is the rotating core inside the motor that generates suction power. A damaged or worn armature causes heavy brush sparking, loss of power, or a burning smell, and it can lead to complete motor failure. Once the rotor degrades, suction never fully returns. A matched armature brings the motor back to proper output. Fits: Ametek Lamb 116311
