Product Description:

The MDD090C-N-030-N2L-110GR2 synchronous servo motor is manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it uses a standard housing and standard rotor balancing, so it can be mounted in general automation equipment without special vibration compensation. In automated machinery, the motor converts controlled current commands into rotary motion for positioning and speed-regulated axes. The motor has size 090 and length code C, which place it within the series by stator stack and overall body depth. It also uses a single shaft end, because there is no extension on side B.

Its nominal operating speed is 3000 rpm. At standstill, the motor can deliver a continuous torque of 10.4 Nm, allowing it to hold a steady load without exceeding thermal limits during continuous duty. A built-in blocking brake can apply up to 11.0 Nm when power is removed, helping prevent drift on vertical or suspended axes. Position feedback is provided through digital servo feedback (DSF), which gives the drive precise rotor angle data for commutation and closed-loop control. This feedback also supports stable speed regulation and accurate positioning during repeated motion cycles. Mechanical alignment is aided by a 110 mm centering diameter that fits standard flange recesses.

Electrical and fluid connections are located on the right side of the stator, and the power interface uses a keyed connector for easier cable removal. Torque is transmitted through a plain shaft, and the output is fitted with a shaft seal to help limit lubricant escape and particle ingress at the bearing face. This arrangement suits direct-coupled pulleys and couplings in machines that use a single driven load. The connection orientation can also help when cable routing must remain on one side of the machine. These features keep the motor layout straightforward for compact installations where space around the drive end is limited.
