Product Description:

The MDD115C-N-020-N2M-130GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into rotary motion for positioning axes, gantries, and similar automated stages. The built-in blocking brake secures machine elements at rest, and the feedback system returns position data to the drive for closed-loop control. This arrangement supports accurate stopping, repeatable travel, and stable correction of load changes during operation. It is suited to machines that must start, stop, and hold position reliably without adding separate external holding hardware.

The housing seats against a centering hub of 130 mm, which helps align the motor with the machine interface. All power and feedback conductors exit on Side A and terminate through a single connector, which keeps cable routing compact and places the electrical connection in one location. This layout can simplify routing where the motor is mounted close to guards or other machine structures. At rated temperature and standstill, the electromagnetic system provides a continuous torque of 47.0 Nm. The blocking brake supplies 45.0 Nm of holding torque to keep the load in place when power is removed. The motor also uses the standard balance class and a size-115 lamination stack.

The nominal speed is 2000 rpm, which suits transfer lines and material-handling stations that use digital servo loops. The integrated multiturn absolute encoder sends Digital servo feedback (DSF) to the controller, so the drive can correct position through acceleration and deceleration without losing track over multiple turns. Absolute position retention over multiple revolutions can reduce the need for repeated homing after controlled power cycles. The motor has a plain shaft with no keyway, which supports clamping hubs and helps minimize radial runout at the coupling. A shaft seal protects the output end from contamination during normal machine use.
