Product Description:

The MDD090B-N-020-N2M-110GR2 is a synchronous AC servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into controlled mechanical rotation for axes that require precise positioning or stable speed regulation in automated machinery. In typical machine service, this type of motor is used where repeatable motion, fast response, and accurate closed-loop behavior are required across changing loads. Its mechanical frame uses size 090 with length code B, and the housing and rotor balancing are standard for general-purpose mounting without added counterweights or external shrouds.

This motor delivers a continuous standstill torque of 7.2 Nm, allowing it to hold or slowly move loads without overheating during low-speed operation. The nominal speed is rated at 2000 rpm, which suits applications that need steady servo response across a typical operating range. A centering diameter of 110 mm keeps the flange aligned with machine plates or gearboxes, and connections are routed on the right side through a coded connector that carries power and signal conductors. Standard shaft sealing protects the internal bearings from airborne particles, and the motor includes an internal blocking brake for load holding when power is removed.

The holding brake develops 11.0 Nm of static torque, which exceeds the continuous output and supports secure load retention during stops or power-off conditions. Position data is supplied by an integrated multi-turn absolute encoder, and velocity feedback is handled through digital servo feedback signals that a compatible controller can process directly. A plain shaft supports coupling to standard hubs or keyless collars, which helps simplify the mechanical connection at the driven end. The encoder and brake are integrated into the motor, so position feedback and load holding are contained within the motor assembly.
