Product Description

We are a professional commutator manufacturer based in Ningbo, China, supplying various types of DC motor commutators, also named motor armature collectors.

Our commutators adopt high-conductivity silver copper segments, matched with high temperature resistant bakelite and mica insulation materials. Strict precision turning and molding process ensures stable dimensional tolerance, low spark, low noise and long service life during high-speed motor operation.

Main types we supply include hook type, riser type, planar type and shell commutators, outer diameter ranges from 4mm to 150mm, customizable segment numbers, inner hole size, height and copper thickness to match different motor rotors.

This component works together with carbon brushes to reverse current direction inside DC armature windings, maintaining continuous stable rotation of micro DC motors, universal motors and starter motors.

Widely applied in power tools (angle grinders, drills, sanders), household appliances (hair dryers, vacuum cleaners, blenders), automobile starter motors, treadmill motors, small industrial DC motors, electric toys and garden tools.

We support OEM & ODM customization, free drawing development according to customer samples or technical drawings, ISO9001 certified production workshop, stable monthly output over 1 million pieces.
