2×(12×32×50 ) carbon brushes and Siemens brush holders for 230kw, 440V voltage, 559A current, 1500rpm rotate speed, 180V exciting voltage, 8.5A exciting current.
Background
The client needed reliable carbon brush and Siemens brush holder assemblies for a G5-280-32B DC motor, rated at 230kW, 440V, 559A, 1500 rpm, with 180V exciting voltage and 8.5A exciting current. This motor was used in a traction system that required high stability, long service life, and minimal downtime.
Solution
We supplied 2 sets of 12×32×50mm carbon brushes paired with Siemens brush holder assemblies. The components were precisely matched to the motor’s performance requirements, ensuring optimal current transmission, low electrical noise, and minimal commutator wear.
Result
The project was successfully delivered, helping the client achieve smooth operation of their traction equipment. The solution improved system reliability, reduced maintenance frequency, and extended the motor’s service life under demanding working conditions.
