R911292021
The R911292021 (MHD112B-048-NP0-AN) is a synchronous motor, produced by Bosch Rexroth Indramat, with functionality as both a servomotor and a main drive motor. As part of the MHD series, it boasts a broad speed range, with a peak torque utilization. The unit comprises a winding code of 048 and a dual cooling method supporting natural convection and surface cooling. Furthermore, it possesses an inbuilt data memory in the encoder, ensuring a smooth and quick startup process. The AC motor may employ additional sensors and actuators for its control and supervision. It is important to avoid improper connections which can lead to high electrical voltage. Storage conditions should be maintained between -20°C and 80°C.
The device is designed for operation within the specifically defined ambient conditions outlined in the product documentation, thus it is unsuitable for use in scenarios such as hazardous goods transportation, medical or nuclear applications, and mining. It is advised to disconnect the device from the power supply before working with voltage above 50V. It is also suitable to ground the unit prior to startup. The motor should not be operated with a malfunctioning emergency stop switch. With digital servo feedback from the encoder, it operates at a maximum speed of 4,500min-1 and can theoretically generate a maximum torque of 102Nm. Specialized transport and mounting equipment are required for handling the device. Disassembly or opening the device under pressure can trigger explosions and result in injuries.
