Product Description:

The MDD025B-N-100-N2K-040PB0 is a small-frame synchronous servomotor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series and developed for digital drive controllers in automated machinery. The unit converts commanded current into rotary motion so that axes such as pick-and-place heads or indexing tables can follow precise velocity and position profiles in real time. Its compact format is well suited to machines where low moving mass and fast axis response are important.

At standstill, the motor can deliver 0.60 Nm of continuous torque, allowing it to hold or slowly move light loads without overheating. During operation, it reaches a nominal speed of 10000 rpm, a high shaft rate intended for short-stroke movements and rapid-cycle equipment. A centering diameter of 40 mm aligns the housing on the machine flange so runout stays within tolerance. Power, feedback, and optional brake wiring exit on the rear face because the connection hardware is mounted on Side B and uses a keyed circular Connector, which leaves the front unobstructed for close-coupled installation. This rear connection layout also helps keep cabling away from the working end of the shaft.

The motor uses resolver feedback integrated with the rotor to return position signals for closed-loop control across the speed range. The size code 025 indicates the motor frame, and the length code B corresponds to the stack length used for this version. A keyed shaft transmits torque to the driven element, and a shaft seal helps protect the internal bearings from dust and oil splash. Because the unit is supplied without a holding brake, applications that need static load retention must rely on drive torque or an external mechanical lock. The design also omits a secondary shaft end, which keeps the working side mechanically simple.
