Electric Motors 1LA9

Electric Motors 1LA9

Three-phase, low-voltage, asynchronous squirrel-cage motors with an aluminum frame.

The three-phase asynchronous motors are designed to drive industrial devices such as fans, pumps, machine tools, presses, etc.

They can be used in a mild climate. Unusual climatic conditions require motors with special manufacturing. Modified motors and special-type motors have been derived from the low-voltage asynchronous motors with a short-circuit armature to serve a wider range of industrial applications and to find more applications in the electric drives of working machines.
