SIMOTICS Motor Generation 1LE1 General Purpose



Motors with aluminum frame

SIEMENS 1LE1 motors with aluminum frame are suitable for a wide range of standard drive tasks in the industrial environment. As a result of their especially low weight, they are predestined for pump, fan and compressor applications. However, they are also admirably suited for conveyor technology and lifting equipment.

Customer benefits

  • Especially user-friendly
    The well-proven terminal boxes introduced for shaft heights 100 up to 160 are now also consequentially used in the complete motor series. The 2 and 4-pole motors, frame sizes 80 and 90 go even one step further: For these motors, the terminal box is only fixed using one screw, and it can be set to any angle between 0 and 360 degrees. In addition, the terminal box has a preconfigured terminal board. This makes it significantly simpler and faster to install motors in restricted spaces, as the motor connecting cable can be routed to the motor from any direction.
  • More power
    Increased output power motors can be the solution if the motor must be extremely compact as there is not sufficient space available for a standard motor. With these motors, in efficiency class IE2, power ratings of a standard motor can be realized in the next smaller shaft height.

Typical applications
