Frame: Integral construction welded by steel plate. The frame and plain bearing housing are fixed on the base plate welded by steel plate respectively.
Stator coil: Laminated by 0.5mm silicon steel fan-shaped lamination. The two sides of fan-shaped lamination is painted with insulating varnish. The stator iron core is fixed on the frame by tighting screw or dovetail rib.
Stator coil: The coil is two layer lap winding. It has B class insulation and can prevent the corona. The end of the coil is wrapped tightly and be integral varnished.
Magnetic pole: Laminated by thin steel plate lamination. The iron core is covered with coil. The whole magnetic pole is fitted on the magnetic yoke.
Magnetic coil: Wound by flat copper wire and has B class insulation after be insulating treated.
Bearing: Composed of cast iron plain bearing housing and plain bearing half-liner casted with alloy. The lubricating method is oilring self-lubricating or compound lubricating with outer oil system.
Brush and collector ring: The collector ring's construction is assembling. The brush is fixed in the constant voltage brush box and connected by the conducting plate. The whole brush support if fixed on the side of bearing.
Exciting mode: T series synchronous electrical machinery are excited by thyristor exciting unit. The exciting unit can be provided by the manufactory.
