Three-phase marine motors for axial-flow ventilators

Specification

The motors have not a terminal – box, but in the frame a gland is
 embodied, through this a cab - tyre cable industrial is brought in
 ( for motors size 90,100,112 from the driving side, for motors size
 132, 160,180 from the non-driving side). The frame construction
 in motors size 160 gives the possibility to screw in three arms fixing
 the motor in axis from ventilation opening.
The motors have not their own ventilator and for their cooling is
 used an air stream pressed through the main fan - propeled by motor.
Motor’s loading with full output can result only in the case when the
 cooling produced by the air stream ventilator will be so intensive,
 that the increase of winding’s temperature noted by resistance method
doesn’t exceeded the temperature of + 105C.
The motors are equiped with the gland protective earth terminal fixed
 on the frame next to and on the nut of the gland ( to neutralize supply lead ).

Protection degree

Motor’s designation with regard to frame’s protection degree.
Designation of motor’ s protection degree according to IEC 60529.
 Marine motors for axial - flow fan have a frame of protection degree IP 55.

Mounting form

Motor’s designation with regard to the mounting form.
Designation of mounting form according to
EN 60034-7. The motors are flange mounting IM 3021
