Product Description:

The MDD090A-N-040-N2M-110GR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it delivers commanded rotary motion for positioning and speed regulation tasks in automated production machinery. An integrated multi-turn absolute encoder furnishes real-time shaft position to the drive, allowing closed-loop operation and coordinated movement with adjacent axes on the line.

The motor has a nominal speed of 4000 rpm under rated voltage and load. Continuous torque at standstill is 3.7 Nm, indicating the holding capability available when the shaft is energized but stationary. A blocking brake is included, and its holding torque of 11.0 Nm secures vertical or suspended loads during power-off events. Position feedback is transmitted through Digital servo feedback (DSF), which supports high-resolution motion control. Mechanical centering is simplified by a 110 mm centering diameter, while standard dynamic balancing minimizes vibration during high-speed cycles. The housing uses a standard sealed design, and power and signal leads exit to the right side so installation suits systems with a right-hand connection direction.

The wiring interface uses a Connector type that maintains shield integrity and provides a secure electrical connection. A plain, backlash-free Plain shaft is provided for coupling hubs, and a shaft seal is fitted to limit lubricant migration while improving protection at the drive end. The rotor-stator package follows motor size 090 and the compact A length code, so the unit occupies minimal axial space yet retains adequate thermal mass for its torque rating. The shaft end is supplied in the standard pattern without a side B extension, and the assembly uses the standard housing and balancing arrangement found on this motor type.
