Synchronous electric motors of СДM4-1250, СДМ(П)4-1500, СДМЗ 4 and СДСЗ 4 types are designed to drive ore- and coal-pulverizing, raw and cement mills, which are used in production lines of mining-and-processing integrated works, cement plants and TPS. The motors can be used both for new construction projects and for replacement of earlier installed motors of old series.

Description:

The motors can be made for voltage 3 000 V or 10 000 V.

Construction of the motors:
by mounting arrangement
• IM7311 or IM7312 by GOST 2479: on base plate, with two pedestal plain bearings, on raised feet, with one or two cylindrical shaft ends;
• IM7321 or IM7322 by GOST 2479: on foundation beams, with two pedestal plain bearings, on raised feet, with one or two cylindrical shaft ends;
by degree of protection of slip rings – IP 11(GOST 17494);
by climatic version and installation category – UHL4 (GOST 15150).
by degree of protection of the case:
• СДМ 4 motors – IP 21;
• СДМП 4, СДМЗ 4, СДСЗ 4 motors – IP 44.
Way of cooling is self-ventilation by open cycle or forced ventilation (by closed or open cycle).

Way of cooling:
– СДМ 4 motors – ICA01 (GOST 20459);
– СДМП 4 motors – ICA37 or ICW37A97 by GOST 20459
– СДСЗ 4 and СДМЗ 4 motors – ICW37A86 or ICW37A81 by GOST 20459 (air coolers are installed directly on the motor case) or ICW37A97 by GOST 20459 (air cooler is installed in base pit).
Environment is not inflammable, not explosive; it is free from aggressive gases and vapours, and it meets atmosphere type II by GOST 15150.

The motors of СДМ 4 type are designed to be installed in premises where concentration of inert dust is not more than 0,2 mg/m3, and the motors of СДМП4, СДСЗ 4 and СДМЗ 4 types are designed to be installed in premises where concentration of inert dust is not more than 2 mg/m3. If concentration of inert dust is more than 2 mg/m3, СДМП4, СДСЗ 4 and СДМЗ 4 motors should operate under overpressure with supplementary clear air inlet with dustiness no more than 0,2 mg/m3.

Insulation of stator and rotor winding belongs to heat-resistance class, which is not below than “F” class.
The thyristor exciters energize the motors.
Terminals of stator winding can be located in the terminal box or can be brought downwards in a base hole. At a customer’s agreement the terminal box may be installed on the case on the right or left (it’s stipulated in the order). At a customer’s agreement, there may be three current transformers in the terminal box (type of transformers is ТОЛ 10-I-1), through which neutral outlets of stator windings (U2, V2, W2) are connected.

In designation of motors СДМ4-1250К(…), СДМ4-1500К(…) and so on, there may be additional character (СДМ4-1250КА, СДМ4-1250КВ, СДМ4-1250КМ, СДМ4-1500LА, СДМ4-1500LB, СДМ4-1500KА and so on), which indicates construction version of the electric motor with overall and mounting dimensions meeting the motors of earlier manufactured series.

The motor designations СДM4-1250, СДM4-1500 are decoded as follows:
СДM 4 – 1250КХ – 24Д УХЛ4:
СДМ – Synchronous mill motor
П – Additional designation (П – blown version)
4 – Series number
1250 – Size by classifier ESKD (1250, 1500)
К – Conventional length of the stator core
Х – Version of the motor by mounting dimensions
24 – Number of poles in the motor
Х – Additional designation (Д – supply voltage 10 000 V)
УХЛ4 – Type of climatic version and installation category

The motor designation СДМЗ 4, СДСЗ 4 is decoded as follows:
СДМЗ 4-2000-48-6 УХЛ4:
СДМ (С) – Synchronous motor (М – mill, С – special)
3 – Additional designation (З – closed version)
4 – Series number
2000 – Power, kW
48 – Number of poles in the motor
6 – Voltage of the motor (3, 6 or 10 kV)
УХЛ4 – Type of climatic version and installation category
