Synchronous motors of СДМ(З)2 type are designed to drive ore- and coal-pulverizing, raw and cement mills, used in production lines of mining-and-processing integrated works, cement plants and TPS. The motors can be used both for new plants and for replacing the motors of old series installed before.

Description:

Motors are rated for operation from AC network, 50 Hz, with voltage 6000 V or 10000 V.
Construction of the motors:
• by mounting arrangement – IM7321 or IM7322 by GOST 2479: on foundation beams, with two plain pedestal bearings, on lifted 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 – УХЛ4(GOST 15150);
• by degree of protection of the motor case СДМ 2 – IP 21; СДМЗ 2 – IP 43.

The motors are cooled by self-ventilation by open cycle (for СДМ2), or in mode of forced ventilation by closed or open cycle (for СДМЗ 2).

Way of cooling:
• motors СДM 2 – ICA01 by GOST 20459;
• motors СДМЗ 2 – ICW37A86 by GOST 20459 (air-coolers are placed directly on the motor case), or ICW37A97 by GOST 20459 (air-coolers are placed directly in the foundation pit).
Environment is non-flammable, non-explosive, it doesn’t contain aggressive gases and steam, it meets atmosphere type II by GOST 15150.

СДМ 2 motors are designed to be installed in premises, where concentration of rock-dust is not over 0,2 mg/m3, and motors СДМЗ 2 – not over 2 mg/m3. If concentration of rock-dust is more, than 2 mg/m3, СДМЗ 2 motors must operate under excessive pressure with adding pure air with dust content not over 0,2 mg/m3.
Heat-resistance class of insulation material of the stator and rotor winding in the motor is not below class “F”.
The thyristor exciters energize the motors.

Designations of SDM2, SDMZ2 motors are decoded as follows:
СДМЗ 2- 22-41-60 УХЛ4:
СДМ – Synchronous motor (M – mill motor)
3 – Additional designations (З -closed construction)
2 – Serial number
22 – Designations of the frame
41 – Active stator length, cm
60 – Number of motor poles
УХЛ4 – Climatic version and installation category
