Trb Motor Brush Dependent upon the design of the trb motor ie GE761, GE752, GE793, GE772, and GE776 the carbon brush may differ in design. Common Grades in use are T900, T959, and T593. All materials are approved by General Electric and are application specific to the trb motor which is specified by General Electric, Trb brushes as employed in “most” General Electric trb motors are of 2 wafer reb brush designs, again aimed at providing brush contact stability over a wide range of environmentally challenging operating conditions
牵引电机电刷根据牵引电机的设计即GE761，GE752、GE793、GE772和GE776的碳刷在设计上可能有所不同。常用的牌号有T900、T959和T593。所有材料均经通用电气批准，并适用于通用电气的牵引电机。“大多数”通用电气牵引电机中采用的牵引电刷均为2片反应电刷设计，旨在在各种具有环境挑战性的操作条件下提供电刷接触稳定性。
