Product Description:
The MDD090A-N-030-N2M-110PR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, where it converts commanded currents into precise rotary motion for industrial automation tasks such as indexing tables, feeders, and gantry axes. The motor is intended for closed-loop operation in systems that require accurate speed regulation and repeatable positioning. The design integrates position feedback and mechanical holding capability so the drive can regulate speed during production cycles and hold the load when power is interrupted. This combination makes it suitable for axes that must stop accurately, restart smoothly, and maintain controlled motion across repeating machine cycles.
A nominal speed of 3000 rpm lets machine builders match the motor to standardized 50 Hz or 60 Hz drive arrangements, while a continuous standstill torque of 3.7 Nm sustains force at zero speed without additional cooling. The blocking brake develops 11.0 Nm of torque to hold vertical or offset loads after shutdown. Mounting concentricity is ensured by a 110 mm centering diameter, and power and feedback plugs exit on the right side to keep harnesses clear of moving parts. A shaft seal prevents lubricant loss and helps guard against airborne contaminants during normal operation.
Electrical terminations use a connector interface for the power and feedback leads. The drive shaft is machined with a keyway so couplings can transmit torque without slippage, and the shaft end is on side A to help keep the overall length shorter. Position data comes from an integrated multi-turn absolute encoder that provides digital servo feedback to the controller for closed-loop operation. The A length code keeps rotor mass lower, while standard balancing supports smooth rotation during normal industrial use. The motor also uses a standard cast housing in the 090 frame size, providing a rigid outer structure for machine mounting.
