Choosing the Correct Motor Carbon Brushes

Start with the reference from the existing motor or carbon brush set. Ametek Lamb motors can use different brushes according to the motor series, voltage and commutator specification, even where the motors are a similar physical size.

Compare the listed brush dimensions and motor details with the original component before ordering. Some products are also specified by commutator bar count, commutator diameter or an auto-stop arrangement, so dimensions alone should not be used to identify a replacement.
