High-voltage HAVING GIVEN electric motors
Electric motors the asynchronous HAVING GIVEN series, three-phase with a short-circuited rotor, are intended for the drive of the mechanisms which are not demanding regulation of frequency of rotation (pumps, fans, smoke exhausters, etc.)
Engines are intended for work from the alternating current main with a frequency of 50 Hz with a voltage of 6000 V.
Type of climatic modification – U3.
Nominal operating mode – long S1.
Design of engines – IM1001.
Way of cooling of engines – IC01.
Degree of protection – IP23.
Launch of engines of a straight line, from the full tension of network. Engines allow two start-up in a row from a cold state or one start-up from a hot state. Interval between the subsequent start-up not less than three hours. Total of start-up in a service life no more than 20000. Engines have rolling bearings with plastic lubricant. Connection of engines with the driving mechanism is carried out by means of the elastic coupling.
Insulating materials of a winding of the stator of a class of heat stability are not lower "In". Isolation of a winding of the stator thermoreactive Monolith-2 type. The winding of the stator has six output ends fixed on four insulators in a box of conclusions.
Connection of phases of a winding – a star. Engines allow the right and left direction of rotation. Change of the direction of rotation is carried out only from a condition of rest.
