Change in supplier of external fans for SIMOTICS M-1PH8 main motors – shaft heights 180 and 225

  • Entry
  • Associated product(s)
There has been a change in supplier of the single-phase EC external fans for the SIMOTICS M-1PH8 main motors in shaft heights 180 and 225 to ebmpapst. The new EC external fans are functionally equivalent and installation-compatible with the previous EC external fans from Ziehl-Abegg.

The change in external fans was concluded in December 2017 and is only valid for SIMOTICS M-1PH8 main motors in shaft heights 180 and 225.

The following SIMOTICS M-1PH8 main motors are affected by this change:

11th position of the article number (for 1PH8)

180

0, 1 or 3, 4

225

0, 1 or 3, 4

The new external fan has new Article No. and Siemens No. designations on the rating plate, making a targeted approach possible.

Configuring and specification

Due to mechanical compatibility and the negligible difference in current consumption (see table), the existing sales documentation and configuration manual remain valid. The operating instructions,  109738144, have been updated and are available in electronic form . 
The dimensions and/or the dimensional disturbing contour of the motor are not changed by the new external fans.

The supply values for the new external fans are specified in the following table, but they can also be taken from the operating instructions:

Note: For EC fans, the current drawn can briefly reach four times the specified current as a result of the electronic input circuitry.
