APPLICATION
The one  speed motors of 3S4 315M-4 type are motors intended for driving mining machines and
equipment, especially for driving getting units of heading machines.
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
" Induction 3-phase motors with welded squirrel-cage rotor,
" Explosion-proof construction with flame-proof casing of motor  d and heavy duty junction box  e
type - mark I M2 EExd I to 1100V, and explosion-proof construction with fire-proof casing of
motor and junction box  d type  mark I M2 EExd I to 1140V, equipment ranked as group I of
category M2 according to Directive 94/9/EC,
" The degree of protection IP 55 acc. to PN-EN 60034-5:2002U,
" The motors are cooled by water flowing through the water jacket of body,
" Forms of execution: special flanged execution  IM 3201 in two versions:
- Version A with one end of shaft for driving getting unit,
- Version B with two ends of shaft for driving hydraulic pump,
" Primary voltage executions:
500; 550; 660; 1000 and 1140V  50H.
After settlement it is possible to execute the motors for other
voltage and frequency of 50/60Hz
" Class of insulation: class H  primary execution, class H + reinforced wound insulation  execution
against order,
" Thermal protection of motors: posistor PTC sensors in winding and bearing nodes  two identical
circuits primary and stand-by and bimetal sensors (NC) in winding two circuits,
" Two-inlet terminal box equipped with one cable inlet with rubber gasket selected to the outer
diameters of conductors, type 54235.2& . or 54345.02 for main circuits and inlets 54232& -M28 or
54242& -M28 produced by GOTHE&Co.
" The motor is equipped with the final link of protection conductor continuity control circuit, mounted in
the terminal box  primary execution: the link 8SX9006-0AA00 (diode + resistor) produced by
BARTEC
" 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/EC (ATEX),
European harmonized standards and domestic norms:
- norms 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
