The SIMOTICS M-1FE built-in motor comprises:

• A laminated, permanent-field rotor, which, as an option, can be designed with a sleeve for simple mounting and removal.
• A wound stator core with cooling jacket and encapsulated winding overhang
  • Free cable ends, length 0.5/1.5 m (1.64 ft/4.92 ft)
  • Two integral PTC thermistors (incl. 1 spare), optionally with full or universal protection
  • A cooling jacket into which the stator has been inserted.

Rotor with sleeve

Torque is transmitted to the spindle mechanically without back- lash by means of a cylindrical stepped press fit. The rotor is mounted on the spindle by thermal shrinking.

The rotor with sleeve is pre-balanced and can be removed and subsequently remounted. The bond can be released by pressure-oil injection without affecting the joint surfaces.

Rotor without sleeve

Torque is transmitted to the spindle mechanically without back- lash by means of a cylindrical stepped press fit. The rotor is mounted on the spindle by thermal shrinking. Removal of the rotor is not possible with this type of mounting. Rotors without sleeves are not pre-balanced.
