VENTORN is OFFICIAL Sales representative of Elko products IN United KingDOm
The company Elko Maribor d.o.o. is the leading manufacturer in the field of development of production and sales of asynchronous electric motors, pumps for clean and dirty – fecal water and foundry products from aluminum alloys and is known both in Slovenia and around the world.
Confirmation of our commitment to the quality of products and services was obtained when we received the ISO 9001international certificate, and our focus on environmental protection was confirmed by awarding us the ISO 14001 international certificate.
Standard three-phase electric motors are built for connection to the Y 400V/50Hz or Y 460V/60Hz network, except for TZF 160 L4 electric motors which are built for connection to the D 400V/50Hz or D 460V/60Hz network. Standard single-phase electric motors are electric motors built for connection to the 230V/50Hz network. The permissible deviation from the rated voltage and frequency is ± 10%. We also make electric motors for other voltages and frequencies by special order.
The insulation of electric motors corresponds to insulation class F according to IEC Publ. 34 or Publ. 85 and DIN VDE 0530/T.1. The heating of the electric motor windings at the rated powers given in the tables corresponds to insulation class B.
In most cases, bimetallic thermal triggers are sufficient for thermal protection of motors. For more difficult motor operating conditions, such as speed control, occasionally elevated ambient air temperatures, several starts or installation in devices with poor cooling conditions, we recommend motor protection with thermal switches or thermistors which are installed in the windings only at the request of customers.

The motors are equipped as standard with a multi-core thermally resistant connection cable. They can be equipped with a terminal box on special request. The cable length (Lk) is given in the dimension table for individual types. On special request, it is possible to obtain a cable with a length that deviates from the data in the table and outlets laterally from the flange.
The rated powers given in the table are the powers emitted by the motors via the flange on the rotor at continuous load, rated voltage and frequency, with ambient temperature not exceeding 40oC and altitude of up to 1,000 m. Motors can also be loaded with increased power during intensive cooling, but only if the heating of the motor winding is measured beforehand.
All single-phase electric motors are made with a permanently connected, i.e. drive paper or metal-paper capacitor. The starting torques of these motors are relatively small and amount to 60% of the rated torque. The motors are therefore suitable for driving fans and other drives where high starting torques are not required.
