Russian company Ruselprom It is engaged in the production of general industrial asynchronous motors with a closed-loop rotor of the DAN series, which are designed to operate as part of a single group frequency-controlled electric drive from an alternating current network in the S1-S9 mode with a frequency of 50 Hz. The advanced manufacturing technology of the stator winding and the design of the magnetic circuit ensure reliable operation of the motors when powered by autonomous voltage inverters and the ability to control the speed in a wide range. Three-phase asynchronous electric motors Ruselprom The DAN series with a short-circuited rotor are designed to drive mechanisms that do not require speed control (pumps, fans, smoke pumps) and other mechanisms with similar characteristics at start-up. The connection of the engine to the driven mechanism must be carried out by means of elastic couplings.
The insulation of the stator winding is thermosetting of the Monolith-2 type of heat resistance class not lower than "B". The stator winding has six terminal ends attached to six busbars in the terminal box. The box is located on top of the engine and allows 180° rotation. The connection of the phases of the stator winding is a triangle/star. The motors allow right and left direction of rotation. The change in the direction of rotation is carried out only from a state of rest. The engines have grease-lubricated rolling bearings. At the customer's request, the engines can be equipped with SKF or FAG bearings.
