APPLICATION

The motors of

SG4 540L-4, SG4B 540L-4, SG4 540L-4A and SG4B 540L-4A

type are intended for driving

mining machines and equipment, and especially for driving getting units of combined cutter loaders.
The motors can be used in underground parts of mines and surface installations of the mines, where there are possible
explosion conditions for methane and/ or coal dust.
There is also possible to operate the motors in the surroundings where the explosion-proof equipment is not required.

CHARACTERISTIC FEATURES OF MOTORS

• The motors are 3-phase induction motors with squirrel-cage rotors,

with power of: 150 kW – motors SG4(B) 540L-4

170 kW – motors SG4(B) 540L-4A,

•

Explosion-proof construction with flame-proof casing of motor „d” - mark

I M2 EExd I, equipment ranked as

group I of category M2 according to Directive 94/9/WE,

• Motors SG4 540L-4 and SG4 540L-4A have soild shaft with driver (moving link) with splines (Fig.2.1).
• Motors SG4B 540L-4 and SG4B 540L-4A have hollow shaft with torsional shaft (Fig.2.2). The torsional shaft gets

devastated during violent locking of the getting unit, and when damaged it can be replaced without need for
disassembly of motor from the equipment.

• The degree of protection IP 55 acc. to PN EN 60034-5:2000U,
• The motors are cooled by water – flowing through the water jacket of body,
• Form of execution – flange execution,
• Primary voltage execution: 1000, 1140V (Y) – 50Hz,

After settlement it is possible to execute the motors for other voltage up to 1140V and frequency of 60Hz,

• Class of insulation: class F – primary execution, class H – execution against order,
• Thermal protection of motors: bimetal sensors NC or posistor PTC sensors - in winding and bearing nodes – two

identical circuits – basic one and stand-by one,

• Thermometric resistors Pt100 are built in winding and bearings for temperature control,
• Two-inlet, two-chamber terminal box equipped with inlet Wk2u/d80... (product of DAMEL) with rubber gasket and

stopper Zk2u which is closing, not used as flame-proof protection, the orifice for cable inlet. The cable inlet Wk2u/d47...
(product of DAMEL) with rubber gasket can be screwed down instead of the stopper.

• Motors are equipped with the final link of protection conductor continuity control circuit, mounted in the terminal box –

primary execution: the final link CK-OA (DAMEL .

After settlement there is possible to assemble the other type of link CK... (e.g. diode + resistor, reverse polarization,
etc.) produced by DAMEL – catalogue card K4-15-121,

• Feeding and start-up: the motors are intended for feeding from power network – start-up by direct switching on the

voltage,

• The motors adapted for work in temperate climate; after settlement the adaptation for work in tropical climate TA or TH

is possible.

COMPATIBILITY WITH REQUIREMENTS OF STANDARDS

The motors meet requirements of Directive 94/9/WE (ATEX), european harmonized standards and domestic standards:
- standards for electrical equipment in areas of explosion hazard:

- EN 50014:1997+A1:1999+A2:1999 – Polish equivalent PN-EN 50014:2002U,
- EN 50018:2000+A1:2002 – Polish equivalent PN-EN 50018:2002U,
- EN 50019:2000 – Polish equivalent PN-EN 50019:2002U,

- standards for rotational electric machines:

- EN 60034-1:1998+A1:1998+A2:1999+AC:2000 – Polish equivalent PN-EN 60034-1:2001

- domestic standards for induction motors for mining machines:

- PN G-38010:1997.
