Key Features
- Genuine OEM Spring Tension Spec — manufactured to the original compression and tension rating required to maintain consistent brush pressure against the motor commutator.
- Drop-In Brush Assembly Fit — engineered to seat correctly within the brush holder housing without reworking or shimming the assembly.
- Broad Collomix Mixer Compatibility — fits CX22DUO, CX22DUOE, CX44DUO, CX44DUOE, CX100HF, CX100HFE, CX300HF, CX400HFE, CX600HF, and CX600HFE models.
- Sustained Motor Contact — correct spring force keeps the carbon brush firmly seated, supporting steady electrical contact and consistent motor output during mixing operations.
- Electrical Safety Consideration — a correctly tensioned brush spring prevents arcing and uneven brush wear that can damage the motor commutator and create heat buildup in the motor housing.
The brush assembly spring in an electric mixer motor maintains constant pressure on the carbon brushes against the rotating commutator. This pressure is what allows current to transfer from the fixed brush to the spinning armature, powering the motor. When the spring weakens or breaks, brush contact becomes inconsistent, leading to arcing, accelerated brush wear, commutator pitting, and ultimately reduced motor power or complete motor failure. Replacing a worn spring promptly extends the service life of both the brushes and the commutator.
