Product Description:

The MDD115C-N-020-N2L-130GB2 is a synchronous motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for use with digital drive controllers in factory automation, where it converts electrical energy from a servo amplifier into precise mechanical rotation. This allows the motor to support coordinated positioning and speed control across linked axes in automated machinery. The motor is built with a plain shaft, a standard housing, and standard dynamic balancing, so it can be installed in gantries, press feeders, and packaging stations without added counterweights or external damping hardware.

The stator and rotor are sized for a continuous standstill torque of 47.0 Nm, so the axis can hold static loads while the drive supplies constant current. During motion, the motor reaches a nominal speed of 2000 rpm. A blocking brake supplies 60.0 Nm of holding torque to keep the load secure after power is removed. The motor uses the MDD 115 frame, with an active diameter of 115 mm, and the length code C indicates the stack height used for this torque class. All conductors terminate through a circular connector, which keeps the power and feedback connections compact and helps maintain the motor enclosure seal.

The centering shoulder measures 130 mm, allowing accurate seating in pilot bores for precise alignment. Power and feedback plugs are located on side B of the housing, so cable runs exit opposite the load side and stay clear of moving parts. Position and velocity signals are transmitted through Digital servo feedback (DSF), allowing closed-loop regulation without additional sensors. This feedback method gives the drive direct rotor position and speed information during operation. The shaft is supplied with a shaft seal, which helps protect the internal bearings from coolant spray and airborne dust.
