Product Description:
The MRS160H-B061-NN is a rotor-stator assembly manufactured by Bosch Rexroth Indramat within the MRS Synchronous IndraDyn H Motors series. It forms the active magnetic core of a permanent-magnet servo stage and is intended for tight-tolerance positioning tasks in packaging lines, pick-and-place modules, and semiconductor tooling. When integrated with an IndraDrive amplifier, it delivers precise torque and speed control for axes that demand high dynamic response and minimal runout.
Protection against ingress is limited to the IP00 classification, meaning all conductive parts must be installed in a clean, filtered compartment. Power and feedback conductors exit through a factory-terminated connection cable, allowing direct routing to the drive cabinet. Continuous thermal performance is maintained when the unit is mounted no higher than 1000 m above sea level, because reduced air density affects heat dissipation. The assembly uses an open kit motor design, so airflow or liquid jackets supplied by the machine builder are required for temperature control. Its magnetic stack corresponds to frame length H, providing additional axial core depth for higher torque than shorter modules.
The frame size of 160 mm establishes the outer mounting envelope, and the electromagnetic layout uses a three-phase synchronous motor arrangement for smooth torque at low speed. The rotor hub leaves an internal clearance of 61 mm, which allows fixture shafts or service pipes to pass through the center without extra machining. Torque transfer to the load is achieved with a compression joint, which creates a shrink-fit interface that helps eliminate backlash between the laminated rotor core and the user-supplied hub. The assembly can be paired with a compatible encoder system required by the selected drive platform.
