Electric motor DC-12 (DS12, DS 12; dc-12; dc12; dc 12)
Electric motor DC-12 - synchronous electric machine, the speed of which is connected with a constant ratio of frequency AC power, which this machine is turned on.
DC-motors 12 are AC generators are used in all cases where needed engine running at a constant speed.
Rated voltage - 220V.
Rated supply frequency - 50Hz.
Power - 12W.
Electric motor DC-12 is designed to drive the tape drives magnetic recording devices and other devices that require a constant speed.
Symbol structure DS-12
- DS - synchronous motor;
- 12 - shaft power, W;
Engines are manufactured in climatic design UHL category 4 according to GOST 15150-69.
Technical characteristics of the DC-12
The method of protection against electric shock motor is class "0", GOST 12.2.007.0-75.
For the DS-12 can have the following deviations from the nominal values:
- Supply voltage - ± 10%;
- Chastotay Power - ± 2%;
- Capacitors - ± 5%.
The average sound level at a distance of 1m from the external circuit of the engine does not exceed 34dB.
Operating position of the DC-12 in space - is arbitrary. Engine operation - long 1 according to GOST 183-74.
For the DS-12 failure operating is not less than 3000 hours. The probability of failure of the engine is not less than 0.95 to 10,000 hours of operating time. Engine life CP-12, which is provided within the operating time of 10000 hours was 6 years.
DC-12 engines are designed for use in the following conditions:
- Height above sea level to 1,000 m;
- Ambient temperature between +1 ° C to +60 ° C;
- Relative humidity of the air - no more than 98% (at a temperature of +25 ° C).
The engine DC-12, packed for transport or in the assembled product, maintains the following effects:
- The ambient temperature range from +60 ° C to -50 ° C.
- Repeated blows to the conditions of transportation, "F" and hit the free fall according to GOST 23216-78.
For optimum performance, the DC-12 environment should be non-hazardous and free of dust, corrosive gases and vapors, which can interfere with the normal operation of the engine.
