Electric motors the VRP asynchronous series three - phase explosion - proof are intended for the drive of the stationary and mobile bottomhole cars and other mechanisms used in the coal and slate mines, rooms and external installations dangerous on gas (methane) and coal dust.
Execution of engines on the level and a type of explosion protection of PB 3B. Degree of protection of electric motors and boxes of conclusions — IP54, fans of an external obduv from an air input — IP20 and an exit of IP10.
Structure of symbol VRP (for example, XXKXPX2,5):
In — explosion - proof;
R — miner;
P — for underground works;
X — height of an axis of rotation, mm (160, 180, 200, 225);
X the adjusting size on a plant louse not of a bed (S, M or L);
To — VRP200, VRP225 electric motors quadripolar with ustanovochno connecting sizes corresponding to EDKOF engines;
X — number of poles (2, 4, 6, 8);
R — the engine with the raised moment;
X2,5 — a type of climatic modification of electric motors (U2,5, T2,5).
– height above sea level to 1000 m;
– ambient temperature from — 45 °C to + 40 °C in a temperate climate and from — 10 ° to + 45 °C in the conditions of tropical climate;
– relative humidity of air to 98% at a temperature plus 35 °C.
Design. Design on a way of installation of VRP160 electric motors, VRP180 — IM1081, and VRP200 electric motors, VRP225 — IM1001.
Electric motors are produced with one cylindrical end of a shaft with two carving openings at an end face.
Connection of phases of a winding of the stator — a star/triangle for all combinations of tension. In the absence of instructions of the customer, electric motors are issued manufacturer connected in a star.
The external fan got on a shaft and protected by a casing is intended for cooling of the electric motor.
Fastening of a box of conclusions allows turn on a corner, multiple 90 ° therefore the cable can be brought from any party.
