Electric point motor with internal locking, non-breakable, contactless, for metro systems, type SP-10BM-A.1, is used in electrical centralization systems at metro stations to organize traffic.
SP-10BM-A.1 is installed on metro switch fittings on the right or left side of the turnout.
The point motor incorporates the following upgraded components and parts:
-
a gearbox with a friction clutch mounted outside its housing;
-
a modular friction clutch with four pairs of discs and cylindrical springs;
-
metal-ceramic parts made of modern composite materials used in the friction-sliding pairs;
-
a newly designed crank switch that eliminates failures typical of a standard crank switch;
-
a removable anti-friction insert under the point blade (slide bar) that prevents wear of the point motor housing;
-
contactless sensors of improved design;
-
a new stamped-and-welded cover with air valves featuring adjustable openings.
