Synchronous СДС motors in the 17th…20th frames and СДСЗ motors in the 17th frame are designed to drive ore-pulverizing, raw or cement mills used in production lines of ore dressing or cement enterprises. Motors are rated to operate from AC network, 50 Hz, with voltage 6 000 V, in continuous S1 operating mode by GOST 183, with power factor сos φ = 0,9

Description:

Degree of protection of the case of СДС motor in the 19th, 20th frames – IP00, of СДС motors in the 17th, 18th frames – IP21, of СДСЗ motors – IP43. At a customer’s request СДС motors in the 19th, 20th frames can be also manufactured with protection degree IP21.

Climatic version and installation category – УХЛ4.

Constructive mounting arrangement:
• СДС motors in the 18th frame – IM7311 or IM7312 by GOST 2479: on foundation plate, with two plain pedestal bearings, on lifted feet, with one or two cylindrical shaft ends;
• СДС motors in the 19th frame – IM 7311 by GOST 2479, with horizontal shaft, on foundation plate, with two plain pedestal bearings, on lifted feet, with one cylindrical shaft end;
• СДС(З) motors in the 17th, 20th frame – IM7321 or IM7322 by GOST 2479: on foundation beams, with two plain pedestal bearings, on lifted feet, with one or two cylindrical shaft ends.

Constructive version by cooling way:
• СДС motors – ICA01 by GOST 20459 (self-ventilation by open cycle, with cooling air intake from the working area through holes in end shields and with heated air discharge through the side holes or shutters in the stator case jacket).;
• СДСЗ motors – ICW37A81 by GOST 20459 (air cooler is installed directly on the motor case), or ICW37A97 by GOST 20459 (air cooler is installed in the foundation pit).
Heat-resistance of insulating materials of the stator and rotor motor winding is not below class “F”.
The thyristor exciters energize the motors.

The motor has temperature control for winding and stator core, bearings.

Terminals of stator winding can be located in the terminal box or can be brought downwards, in the foundation hole (it’s agreed, when motor production is ordered).

СДС motors are designed to be installed in premises with rock-dust density not over 0,2 mg/m3, СДСЗ motors – not over 2 mg/m3; environment is non-flammable, non-explosive, it doesn’t contain aggressive gases and steam, it meets atmosphere type II by GOST 15150.

Explanation of designation:

СДС – Synchronous motor (С – special)
3 – Additional designation (З – closed version)
17 – coded designation of the frame
76 – Active length of the stator, cm
12 – Number of poles
УХЛ4 – Climatic version and installation category
