Marine Low-Noise Motors of 3 DMSh Series with Increased Requirements to Vibroacoustic Characteristics 

3дмш_1000.jpgInduction motors of 3DMSh 63-180 and 3DMShOV 63-100, 3DMSh 63-180 and 3DMShOV 63-100 series  

Induction motors 3DMSh 63-180 and 3DMShOV 63-100 are manufactured in accordance with technical specifications 16-525.662-86; 3DMSh 90-112 and their modifications are manufactured in accordance with technical specifications 16-525.590-84. Motors 3DMSh 132-200 and their modifications are manufactured in accordance with technical specifications 16-525.591-84. Marine three-phase squirrel-cage motors are designed for marine machinery drives (fans, air conditioners, pumps, compressors) for operation in the unrestricted navigation area. Electric motors can be manufactured for all climate regions (including marine, cold, tropical, etc.) on a customer’s request. Motors meet the requirements of GOST 183-74, technical specifications, GOST B 23396-78 and Terms of delivery No. 01-1874-62. These motors are distinguished from the motors 2DMSh due to a more precision material machining and application of low-noise bearings. Motors are designed for three-phase AC power supply, 50Hz, 380V. Mounting arrangement corresponds to GOST 2479-79 and shall be discussed while placing an order. Rated operating mode is continuous duty (S1) according to GOST 183-74, operation in temporary duty (S2) is permitted as well. Environmental protection degree is IP55 according to GOST 14254-80. Cooling method is IC0141 according to GOST 20459-87 (with a self-blowing cooling fan), except for motors 3DMSh 63-80 (without a self-blowing cooling fan) IC00 and motors 3DMShOV 63-100 - IC19 according to GOST 20459 (which are blown with a machine fan mounted on the motor shaft). Induction motors 3DMSh 63-180, 3DMSh 63-100, 3DMSh 90-112 and 3DMSh 132-200 have a rated power range from 0.12 to 18.5 kW.    

In addition to the main version of 3DMSh, the following modifications are available:  

3DMShOV - for axial flow fan drives;

3DMShN - for pump drives;

3DMShM - low-magnetic version;

3DMSh2K - for compressor drives.


Marine Induction Motor of 3DMShR160МА4-ОМ5 Series  

Marine three-phase squirrel-cage induction motors 3DMShR 160MA4-OM5 are designed for shaft-turning gear drives and manufactured in accordance with technical specifications 16-89. Motors are designed for operation in the unrestricted navigation area. Motors meet the requirements of GOST B 23396-78 and Terms of delivery ...No. 01-1874-62.

Electric motors can be manufactured for all climate regions (including marine, cold, tropical, etc.) on a customer’s request. Mounting arrangement is IM1001 and IM3012 in accordance with GOST 2479-79. Rated operating mode of the motor is continuous duty (S1) according to GOST 183-74. Protection degree of the motor, based on the degree of internal parts protection against the intrusion of solid objects and water, is watertight according to GOST B 23396-78 (IP55 according to GOST 14254-96). Cooling method is IC0141 according to GOST 20459-87. Motor is designed for the voltage of 380V, 50Hz.
