Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-020-N2M-130GB1 as part of the MDD Synchronous Motors series. The unit is a permanent-magnet synchronous motor intended for digital drive controllers in automated machinery. It converts regulated current into mechanical rotation for positioning slides, index tables, or moderate-speed tool drives. Its permanent-magnet design supports responsive servo operation in applications that require accurate starts, stops, and controlled holding at low speed. A standard housing and rotor balance allow straightforward frame mounting, and the integrated blocking brake safeguards stationary axes during power loss or service.

The motor sustains a continuous standstill torque of 7.2 Nm, so it can support steady load at zero speed without thermal overload. Its nominal speed of 2000 rpm suits applications that need controlled yet energetic rotation, such as palletizers or pick-and-place gantries. Precise alignment is achieved through a 130 mm centering diameter that mates with standard mounting flanges. All power and feedback conductors emerge through a connector, and the connection is located on side B, so cables route toward the rear of the motor. Standard rotor balancing helps reduce vibration during repeated acceleration and deceleration. The housing also dissipates heat through its aluminum ribs during extended duty periods.

An internal brake provides 6.5 Nm of holding torque, locking the shaft when drive power is absent. Position data come from an integrated multi-turn absolute encoder, and the signals return to the controller through digital servo feedback (DSF) for closed-loop motion. A shaft seal helps block coolant or oil ingress, while the plain shaft accepts clamp or compression couplings without keyways. This feedback arrangement allows the drive to monitor shaft position through repeated indexing and stop-hold cycles.
