Product Description:
The MDD090A-N-040-N2M-110PB1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built for digital drive controllers, it converts regulated DC bus energy into precise rotary motion for positioning, feed, and auxiliary axes in automated production cells, packaging equipment, and material-handling lines. Its compact dimensions, integrated feedback devices, and standardized mounting pattern allow direct installation in multi-axis systems without intermediate transmission stages. This motor is suited to applications that require repeatable starts, stops, and speed changes under closed-loop control.
Mechanical alignment uses a centering pilot of 110 mm, and cables exit on side B to suit panel-mounted drives. The rotor delivers 3.7 Nm of continuous standstill torque, and closed-loop operation is supported up to 4000 rpm. An integrated multi-turn absolute encoder tracks shaft position over multiple revolutions, and the controller receives this information as digital servo feedback (DSF) signals for precise speed and torque regulation. Standard dynamic balancing reduces residual vibration during operation. The motor uses a standard housing finish for typical shop environments, carries frame size 090 with length code A, and omits a non-drive-end shaft extension to keep the overall depth short.
When motion stops, the built-in blocking brake holds the rotor with 6.5 Nm of static torque to help prevent drift on vertical axes. All power, brake, and feedback conductors are routed through a single industrial connector, which keeps cabling consolidated at the motor. Using one connection point also helps keep cable routing compact in confined machine layouts. A factory-installed shaft seal helps protect the bearings from process fluids. The drive end uses a keyway so torque can be transferred to couplings without slip.
