Product Description:

The MDD090B-N-020-N2M-110GB1 is a synchronous motor built by Bosch Rexroth Indramat and included in the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers regulated rotation so automated axes follow velocity or position commands without transmission slack. The unit is motor size 090 and uses a standard housing that suits general industrial mounting arrangements. Standard balancing keeps residual vibration within limits normally requested for precision machining lines, and the integral blocking brake maintains shaft position once power is removed.

During operation, the motor reaches a nominal speed of 2000 rpm, which sets the synchronous electrical frequency required from the drive. At standstill, it can apply a continuous torque of 7.2 Nm, enabling stable static load support without overheating. When the integrated brake is engaged, a holding torque of 6.5 Nm prevents back-driving of vertical or indexing loads. Position information comes from the integrated multiturn absolute encoder, and this sensor lets the controller read shaft position over many revolutions without a homing routine after power cycles. Real-time state data are transmitted through digital servo feedback, giving the drive high-resolution velocity and position loops.

Mechanical interfaces follow industry dimensions. The centering flange is machined to 110 mm, which aligns the motor concentrically with the driven equipment. Power and feedback wires exit through a sealed connector on side B, allowing quick exchange during service. A shaft seal keeps lubricant inside the standard shaft end while blocking contaminants. The motor has a plain shaft, so torque is transmitted with external couplings rather than a keyed joint. The motor has motor length code B, which gives it a medium frame depth that balances torque density with cabinet clearance.
