Product Description:

The MDD025B-N-100-N2G-040ME0 is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts commanded current into precise rotary motion that can be controlled in a closed loop by the associated drive. The unit’s compact size and configuration make it suitable for positioning axes in pick-and-place modules, small spindle drives, and similar automation tasks where high-speed operation and low inertia are important. This type of motor is typically used where quick starts, short move times, and repeatable positioning are needed in a small installation space.

At stall, the rotor can generate 0.60 Nm of continuous torque, a level that provides the force available for static holding or slow-speed feed duties without overheating. When released to rated operation, the shaft reaches 10000 rpm, allowing fast indexing or high surface speed in light machining. A centering diameter of 40 mm aligns the flange with mounting fixtures and helps minimize radial runout. Electrical and feedback conductors exit on the left side because the connecting cable with coupling unit is fixed on that side. Power is transmitted through a keyway shaft end so torque can be transferred reliably to pulleys or gear sets without slip.

The rotor uses standard balancing quality, so additional field balancing is not required at rated speed. Position information is provided through resolver feedback, giving rotor angle feedback across the speed range. For applications that use external braking devices, the motor is supplied without a blocking brake. It is also supplied without a shaft seal, so clean installation conditions or an external seal are required. The coded dimensions identified by motor size 025 and length B keep overall weight low for quick dynamic response.
