Product Description:

The MRS202D-1N-0096-NNNN is a synchronous motor produced by Bosch Rexroth Indramat and assigned to the MRS Synchronous IndraDyn H Motors series. Designed for high-power servo applications, the unit provides constant torque and accurate speed regulation to presses, extruders, and other industrial axes that demand tight motion control. By combining a permanent-magnet rotor with feedback electronics, the motor integrates easily with IndraDrive controllers for automated assembly and processing lines. It is also suited to direct-drive arrangements where stable torque and repeatable response are important as process loads change during operation.

Its continuous operating data show how the motor interacts with the drive during normal operation. The rated winding draws 53 A, a current level that the power stage must supply without thermal derating. At this electrical load, the shaft outputs 29 kW while turning at a nominal speed of 1700 rpm. Under these steady conditions, the electromagnetic system delivers a shaft torque of 163 Nm, providing the force needed by medium-to-heavy machinery. A bore machined as a smooth hole passes completely through the rotor, supporting shrink-fit coupling to a driven shaft or mounting mandrel without the stress concentrations associated with keyed designs.

For transient events such as rapid acceleration or impact loading, the drive may momentarily supply up to 147 A. This surge lets the magnetic circuit produce a peak torque of 407 Nm without loss of synchronization. The central opening measures 96 mm in diameter, allowing large through-shafts or fluid lines to pass through the motor. Dynamic response is influenced by a rotor inertia of 0.077 kg·m², specified with a tolerance of ±10%, so motion tuning can account for minor mass variation. The 19.6 kg rotor also adds stored rotational energy, which can help smooth short-term speed changes during demanding machine cycles.
