Product Description:

Bosch Rexroth Indramat builds the MDD090B-N-020-N2M-130PL1 as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it supplies closed-loop torque and speed to automated machinery such as tool changers, indexing tables, and handling modules. By combining a permanent-magnet rotor with internal position sensing, it enables the drive to issue precise current commands for repeatable motion sequences in industrial cells. This arrangement supports accurate axis movement during repeated start, stop, and positioning cycles in compact machine stations.

In operation, the motor reaches a nominal speed of 2000 rpm, allowing standard drives to keep mechanical transmission ratios modest. A continuous standstill capability of 7.2 Nm supplies holding torque during dwell periods without thermal overload. Alignment during mounting is aided by a centering diameter of 130 mm, while standard balancing helps limit residual vibration for smooth rotation at maximum operating speed. Position data originate from an integrated multi-turn absolute encoder, and its signals are transmitted as digital servo feedback (DSF) to the controller, removing the need for external converters. The motor body uses a standard housing, its cabling exits to the left side for layouts that favor that orientation, and a connector interface on the stator mates power, brake, and feedback lines. The shaft is supplied without a second extension so accessory pulleys or couplings can be mounted directly.

The blocking brake provides 6.5 Nm of static torque once power is removed, and it is wired through the same connector that serves the windings. Drive torque is transmitted by a keyway machined on the output shaft, and a shaft seal helps prevent lubricant ingress. The motor has length code B and frame size code 090, which keeps the package compact for multi-axis modules where footprint is limited. The standard housing also supports installation in machine sections where surrounding space must be used efficiently.
