Product Description:
The Bosch Rexroth Indramat MRS202D-2N-0085-M240 belongs to the MRS Synchronous IndraDyn H Motors series and functions as a direct-drive component for precision servo axes in industrial automation. By generating synchronous torque without mechanical transmission stages, the motor supports positioning, contouring, and cyclic motion tasks in packaging, printing, and material-handling systems. Because the load is driven directly, the arrangement reduces backlash associated with intermediate drive components and supports accurate motion response. Its design also supports integration with compatible Rexroth drive controllers and machine frames that require tight dimensional tolerances and predictable thermal behavior.
The motor uses frame size 202 with frame length D, so the mounting structure must provide enough room for its diameter and axial length. These dimensions also affect the surrounding clearance needed for nearby machine components and the available installation space on the mounting surface. The electromagnetic layout uses 5 pole pairs, which sets the electrical frequency in relation to shaft speed and influences running smoothness across the operating range. The rotor has an 85 mm rotor bore, providing clearance for through-shafts, cooling passages, or clamping elements inside the motor body. Final seating on the machine shaft is achieved with a step interference fit, so the hub is pressed onto a machined step for secure torque transmission without keys or external couplings.
The rotor has a 0.084 kg·m² rotor inertia, which affects how quickly the axis can accelerate or decelerate when drive current changes. It also has a 23.0 kg rotor mass, which contributes to the moving mass supported by the surrounding mechanical system during operation. Radial sealing between the rotor hub and mating hardware is handled by an 85 × 4 O-ring installed in a dedicated groove, helping maintain a controlled interface at the hub. The seal uses 75FKM, a material selected for resistance to hydraulic oils and elevated temperatures found in enclosed servo modules.
