Three-phase asynchronous crain electric motors of series MTФ--411-6, MTФ--412-6, MTН-411-6, MTН-412-6, MTF--411-8, MTФ--412-8, MTН-411-8, MTН-412-8 with a phase rotor

Engines are intended for a drive crain and other mechanisms working in short-term and is repeated-short-term modes, including with frequent start-up and electric braking.Engines can be used also for mechanisms of a long operating mode.

Engines are intended for a feed from a network 380 B, 50 Hz with three deduced ends from a winding статора, and also can be made on a pressure 220/380 and 380/660 B with six deduced ends for connection of phases in a star or a triangle.

At will of the customer enines on other pressure and frequencies are made.

Engines MTФ, MTH are made with a phase rotor.

Engines MTФ are intended for a temperate climate (execution У1), enines MTН are intended for works at the raised temperatures (execution У1), for a tropical climate (execution Т1) and for a cold climate (execution ХЛ1).

Cooling of enines — external having blown (IC 0141).

Degree of protection of enines — IP 44, a degree of protection of a box of withdrawal and the hatch of contact rings of enines — IP 54.

The dimensional and adjusting sizes

The basic design on paws with one end of a shaft (1М1001). will of the customer electric motors can be carried out with two identical ends of a shaft, and also in execution with a flange on paws with horizontal and vertical shaft.
Engines MTФ, MTН correspond to GOST and to requirements of normative documents MEK. Engines of type МТ have certificates of conformity on safety of State standart of the Russion Federation.
