1MR376A-B225

The Bosch Rexroth Indramat 1MR376A-B225 is a high-performance motor in the 1MB High-Speed Asynchronous Motors series. Designed for demanding motion-control applications, it features an inner rotor diameter of 225 mm and a compact motor length of A, with a robust motor size of 376 for handling high-speed tasks. Its primary function is to drive precision equipment such as grinding machines, machine tools, and printing presses, delivering reliable torque and acceleration in industrial environments.

This model integrates advanced features to ensure precise operation and system protection. The rotor assembly incorporates a built-in position encoder to provide accurate feedback on shaft position, while a dedicated temperature tracking sensor monitors winding temperature in real time. The rotor has an IP00 protection rating, requiring careful handling, and is designed to operate within a recommended ambient temperature range of 0 to +40 °C at altitudes up to 1000 m MSL. To manage thermal loads effectively, the stator employs a liquid cooling system and can accept an optional aluminum cooling jacket for enhanced heat dissipation.

Additional design elements contribute to the motor’s durability and efficiency. The American-specification rotor and matched stator configuration ensure consistent performance and ease of integration with compatible drive controllers. The liquid cooling arrangement minimizes power loss and heat buildup, extending the service life of the winding insulation and reducing maintenance intervals. Operating within its specified thermal and altitude limits, the 1MR376A-B225 delivers stable, long-term performance in continuous-duty industrial applications. Its precise control capabilities and robust construction make it an ideal choice for high-speed automation systems, enhancing productivity and reducing total cost of ownership.
