8.7.4 Inspection steps for EDR..71 – 315, EDRN63 – 315 brakemotors
WARNING
Risk of crushing if the drive starts up unintentionally.
Severe or fatal injuries.
• Disconnect the motor and all connected options from the power supply before
you start working.
• Secure the motor against unintended power-up.
1. With gearmotors: Remove the motor from the gear unit. Remove pinion and oil
flinger [107].
2. Remove forced cooling fan and rotary encoder, if installed. See the chapter " Motor
and brake maintenance – preliminary work" (→ 2 141).
3. Remove the fan guard with encoder mount [212] or fan guard [35] and the fan fan
impeller [36].
4. EDR..90 – 315, EDRN63 – 315 motors : Remove the brake cpl. [550] (if applica-
ble) with mounted /HR, /HF option manual brake release.
• BE03 – 11 : Remove the terminal box cover and loosen the brake cable from
the connection terminals.
• BE20 – 122 : Loosen locking screws of the brake plug connector [698] and re-
move plug connector.
• Loosen screws [13]/[19]/[900], press brake [550] off the endshield [42], and
carefully lift off the brake.
5. Remove stator:
• EDR..71 – 132, EDRN63 – 132S motors: Remove cap screws [13] from
flanged endshield [7] and B‑side endshield [42]. Remove stator [16] from
flanged endshield [7].
• EDR..160 – 180, EDRN132M – 180 motors: Loosen hex head screw [19] and
remove B-side endshield [42]. Loosen hex head screw [13]/[15] and remove
stator from flanged endshield [7].
• EDR..200 – 225, EDRN200 – 225 motors
– Loosen hex head screw [15] and remove flanged endshield [7] from stator.
– Loosen cap screws [19] and remove the complete rotor [1] together with the
B-side endshield [42].
– Loosen cap screws [25] and remove the complete rotor [1] from the B-side
endshield [42].
• EDR..250 – 280, EDRN225 – 280 motors without /ERF or /NS option
– Loosen cap screws [15] and remove the flange [7].
Push or pull the rotor [1] and take the flange [7] along evenly.
– Loosen cap screws [19] and remove the B-side endshield [42] together with
the rotor [1].
– Loosen cap screws [25] and remove the B-side endshield [42] from the rotor
[1].
• EDR..250 – 280, EDRN225 – 280 motors with /ERF or /NS option, or EDR../
EDRN315 motors
– Loosen cap screws [19] and [25] and remove the B‑side endshield [42].
