T series synchronous motors

T series synchronous motors

Three-phase synchronous electric motors of the T series are designed to drive fans, pumps, electric generator sets and other universal equipment. The rated voltage of the motors of this series is - 10 000 V; upon customer request, it can be manufactured with a voltage of 6 000 V. Rated power factor (cosφ) - 0,9.
The motor can be started directly at rated voltage. When starting, a starting resistor load must be connected in series to the rotor circuit, the resistance of which is 10 times greater than the resistance of the field winding.

•Three-phase electric motors of the T series have a horizontal design. Cooling methods include open self-ventilation, tubular or semi-tubular ventilation, and closed self-circulating ventilation.

•T-Series motors can be manufactured with single or double-sided output bushings. The direction of rotation when viewed from the commutator side is - counterclockwise. If necessary, the direction of rotation of the motor can be changed, but in this case the fan wheel must be adjusted accordingly.

•Bearing shield

Made in the form of a monoblock structure, welded from steel. The bearing shield and main plate are fixed to a prefabricated steel platform.

•Stator core

Assembled from overhead plates of electrical steel 0.5 mm thick, arranged in a package. Tension bolts secure the stator core to the bearing shield.

•Stator winding

An overhead winding with class F insulation and anti-corona measures is used. The ends of the winding are securely fixed and subjected to general vacuum -pressed impregnation (VPI).

•Poles

The pole core is assembled from thin steel plates on which the pole winding is mounted. All poles are mounted on the hub.

•Pole winding

Wound from flat copper wire and treated with Class F insulation after manufacture.

•Bearings

They consist of a cast iron bearing shield and a bean alloy bearing sleeve. Lubrication method - self-lubrication with a finger or combined lubrication with an external oil system.

•Brushes and commutator

The collector has a prefabricated structure. The brushes are installed in fryers with constant pressure and are connected to each other by means of conductive plates. The entire frying structure is fixed to the side of the bearing.

•Excitation method

The exciting device for the motors of this series is a thyristor exciting device, which can be supplied as a set by our company at the customer's request.
