Product Description:
The MDD090B-N-020-N2M-130PB0 synchronous motor is produced by Bosch Rexroth Indramat for use in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into rotary motion for positioning and process axes in industrial automation. Its synchronous design supports closed-loop motion where the controller regulates torque and speed with encoder feedback. The size 090 frame and B length code set its mechanical envelope, while the standard housing and standard rotor balancing support stable operation in machine assemblies.
The motor’s centering pilot measures 130 mm, allowing firm alignment to mounting flanges for accurate installation. Electrical and feedback conductors exit on the rear because the power and signal connectors are arranged on Side B, an orientation that keeps cable loops out of the working envelope. At standstill, it can deliver 7.2 Nm of continuous torque, so the drive can support static loads without extra cooling hardware. The nominal shaft speed of 2000 rpm works with that torque to establish the continuous operating range. Position data are produced by an integrated multi-turn absolute encoder, giving the controller immediate absolute angle information after power-up without requiring a homing cycle.
Because the unit is supplied without a blocking brake, any hold-position requirement must be met by drive torque or external clamping, which helps keep overall mass low. Motion feedback reaches the drive through digital servo feedback signals that match Indramat controllers. The motor transmits torque through a keyway shaft for standardized couplings. A shaft seal is installed to protect the internal bearings when the motor is mounted in dusty or oil-laden areas. The single-ended shaft layout and plug-in connector arrangement help keep the installation compact in multi-axis assemblies.
