An armature is made up of many different parts which requires specialized experience in order to repair properly. The armature contains a winding, commutator bar, and an armature shaft. Below, we will walk you through how we take special care throughout the repair process. Our overview will cover how we rewind armatures, how we repair the commutator, cover machine work for armatures, and the importance of balancing armatures.
The lamination stack of an armature must be in good condition and our experienced technicians inspect the laminations before rewinding. Repairs are conducted on the laminations or simply a new lamination stack is manufactured. When the armature is ready for rewinding, our winders follow precise rewinding steps which include manufacturing of the coils and inserting of the coils.

Please note that we are not able to wind small power tools, vacuum blowers, automotive 6 or 12v, lift trucks 12, 24,36, 48v or golf cart armatures.

The commutator is vital to the longevity of our customers’ armatures. Our machinists and technicians must ensure that we create a smooth surface in order for the brushes on a DC motor to pass over the commutator smoothly and transmit electrical currents to the armature windings.

Our machinists inspect all motor shafts during our repair process. This is to ensure that the shaft meets the OEM specifications for tolerances. When an armature shaft does not meet tolerances, our machinists can repair the shaft. To understand more about our machining capabilities, click here: Complete Machine Shop

If a rotating apparatus is not balanced, the equipment will experience vibration most likely resulting in premature failure. Our trained balancers balance armatures to the tightest of tolerances to ensure the reliability of an armature repair. Check out more about balancing and our strict standards here: Dynamic Balancing
