R911293228
The R911293228 (MHD115B-024-PP0-LA) is a synchronous motor, expertly crafted by Bosch Rexroth Indramat. During assembly, cover screws should be tightened to torques of 1Nm and 3Nm to ensure an IP 67 protection rating. The motor should not be exposed to conditions outside the stated degree of protection. Its housing provides excellent resistance against discoloration, weathering, and chalking. For continuous start-stop operations with high repeat frequencies, an additional blower may be required, purchasable separately. Surface cooling is not recommended if the motor has been shock-decoupled for use with punches or presses.
Equipped with a keyway shaft, the motor allows for keyed torque transmission in a consistent direction, ensuring minimal shaft-hub connection requirements. Its shaft sealing ring is a rubbing seal, susceptible to wear and the production of frictional heat. The motor has a C length code, a winding inductivity of 5.3mH, and a type plate with specific motor details. For transport or storage, it must be horizontally oriented. Installations should be done mechanically before establishing electrical connections. The encoder connector should be positioned correctly on the thread of its connection housing. Prior to maintenance or repair, ensure the motor is de-energized and the power switch is turned OFF. It’s shipped in robust packaging for protection.
