The Bosch Rexroth R911288396 (MHD115B-024-PP1-AA) is a synchronous motor featuring a 70Nm electrically releasing holding brake that requires proper grounding before initiation. Operational reliability of the holding brake must be checked before startup. Correct connections to its related drive controller must be established for it to function properly. Its functionality might be compromised by excessive dust or shavings. Routine cleaning of the motor cooling ribs is necessary for heat radiation. Operation at high temperatures could lead to a shortened bearing service life. Regular inspections for damaged connection lines and loose connectors are recommended; bearings should be replaced if noisy or at the end of their service life. This 4.4kW motor includes overload protection through temperature monitoring and boasts a wide range speed range, high overload capability, and optimal heat dissipation. Incorporating both electrical and electronic commutation, it also supports the direct mounting of belt pulleys and pinions with bearings that withstand high radial loads.
