Synchronous three-phase motors series СДЭ2 are designed to complete converter units of excavators. They may be used for drives of different mechanisms on agreement between the customer and the plant-manufacturer. Designed for operation from AC mains supply 6000 V and 10 000 V, frequency 50 Hz.

Description:

Climatic version У, ХЛ and T, location category 2.. The motors parameters of climatic version T are to be coordinated in every concrete case with the plant-manufacturer.

Rated mode of operation is continuous S1 with alternating loading.

Ambient temperature from – 45º C to + 45º C is for climatic version “U” and from – 60º C to + 45º C is for climatic version “ХЛ”
Design version of the motors as to the mode of mounting is IM1102, cooling method. – ICA21. Degree of protection of the motors is IP21, for the outlets box is IP44.
Insulation of the stator and rotor windings is of class “F”.

The motors are self-ventilated, air supply from the premises through shields, air ejection is under the assembly plate.

Excitation of the motors is performed from thyristor excitation arrangements. On customer’s requirements excitation of motors can be performed from electric machine excitation unit which is a part of the converter set as well as the motor or from separate excitation unit.
