Bosch Rexroth Indramat's R911288396 (MHD115B-024-PP1-AA) is a state-of-the-art synchronous motor equipped with a 70Nm electrically detonating holding brake. It's essential to ground the motor correctly and ensure the holding brake's operational reliability before starting. The device must be paired with the proper drive controller after all connections have been correctly arranged. Striking a balance between performance and precaution, the unit is designed with large heat radiation to avoid overheating and potentially damaging effects of dust, dirt, or excessive shavings. Regular cleaning of the motor ribs is mandatory. However, operating at extreme temperatures could shorten its bearing service life. The R911288396 (MHD115B-024-PP1-AA) implements impressive dynamics and high overload capability across a vast speed range, along with a high torque to inertia mass ratio. Routine device checks, particularly for tightened seating connectors and damaged connection lines, must be performed to maintain the motor's performance and longevity, rated at 4.4kW. Bearing replacement is advised at the first sign of noise during operation or when their lifespan is reached. Enhanced with distinctive features like electrical and electronic commutation plus special magnetic materials ensure low inertia mass. The protection against overload is courtesy of its unique temperature monitoring function, and after obtaining this device, a one-year maintenance support is included. The model also allows direct mounting of belt pulleys and pinions.
