MDD093B-N-020-N2L-110PB0 by Bosch Rexroth Indramat

The MDD093B-N-020-N2L-110PB0 is a three-phase permanent-magnet servo motor engineered by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical commands from an axis drive into precise mechanical torque for coordinated motion in pick-and-place stations, packaging lines, and conveying systems. Its thermal characteristics and feedback interface support integration into multi-axis assemblies that require accurate speed, position, and torque control throughout repetitive operating cycles.

The rotor is balanced to the standard grade, and a centering pilot of 110 mm aligns the flange with a gearbox or machine frame. The output shaft has a keyway for positive torque transmission, while the fitted shaft seal helps protect the internal bearings from coolant and dust. Rated continuous torque at standstill is 14.5 Nm, allowing the motor to sustain static torque without exceeding its continuous thermal capacity. Under rated excitation, the motor reaches a nominal speed of 2000 rpm, providing low-speed torque while supporting faster indexing cycles. Power and feedback conductors exit on side B of the housing, allowing the cables to be routed according to the motor's mounting orientation. The flange, shaft, and cable exit arrangement should be considered when establishing clearances around the installed motor.

Electrical connections use a connector interface that mates with compatible motor cables and provides a secure connection for the conductors. Rotor position is reported through digital servo feedback, giving the drive the information required for high-resolution closed-loop control. The motor has frame size 093 and length code B, providing a consistent housing envelope within the MDD series. Its housing has the standard finish, and the shaft has no side-B extension, which keeps the motor within its intended overall length. The motor is supplied without a blocking brake, so drive torque or an external holding device must secure vertical loads when motor power is removed. This brake arrangement must be considered when the connected mechanism could move under gravity while the drive is disabled.
