Hitachi Circular Saw Parts

Product Details
Brand: Hitachi
Part Number: 990112U


The armature is one of two main components of a motor (along with the field). It has copper windings around it and has a commutator where the brushes make contact to complete the circuit. If large gaps appear between the copper commutator sections, it must be replaced. If burnt, the commutator can sometimes be “dressed” and cleaned. Check for burnt or damage winding and wires when diagnosing.
