Insulated bearings
Frame sizes 225 and 250:
For converter operation it is recommended that an "insulated
bearing cartridge NDE" – order code L51 be used.
Frame sizes 280 to 355:
For ordering with order codes B40/B41/B43/B44, the "insulated
bearing cartridge NDE" is included as standard.
Frame sizes 400 and 450:
For ordering with order codes B40/B41/B43, the "insulated
bearing cartridge NDE" is included as standard.
The data on the separate rating plate for converter operation apply
to both constant torque drives and pump/fan/compressor
drives. For a constant torque drive, the resulting thermal motor
torques in the positioning range must be taken into account.
