They conduct electricity to the rotating armature, allowing the motor to run. As the motor operates, the brushes gradually wear down from friction against the commutator. When brushes become too worn, the motor will lose power, run erratically, or stop working entirely. Regular replacement of carbon brushes is essential preventive maintenance for your Bernina machine.\u003c\/p\u003e\u003ch3\u003eNew Style vs. Old Style Motor Brushes\u003c\/h3\u003e\u003cp\u003eBernina has used different motor brush sizes over the years:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew Style (Part #323.658.03):\u003c\/strong\u003e 4.8mm x 5.8mm x 13mm - this product\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOld Style (Part #324.250.080):\u003c\/strong\u003e 3.8mm x 4.3mm - for vintage 700\/800 series models\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAlways verify which size your motor requires before ordering.
