MDD025C-N-100-N2G-040GF1
The MDD025C-N-100-N2G-040GF1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for operation with digital drive controllers, where commanded current is converted into precise rotary motion for compact positioning tables, pick-and-place heads, and auxiliary spindles in automated equipment. Because it is built for closed-loop servo duty, the motor can support repeated starts, stops, and direction changes with accurate control. Its compact format also suits small machine modules where available mounting area and moving mass must both be kept under control.
The motor delivers a continuous standstill torque of 0.90 Nm, which is suitable for light direct-drive loads and for holding position while the axis remains energized. At rated operation, the rotor can reach 10,000 rpm, supporting applications that demand short cycle times and rapid speed changes. A blocking brake in the end bell provides 1.0 Nm of static torque to hold a vertical load after power is removed. Motion feedback is supplied by resolver feedback, allowing the drive to monitor rotor position with analog sine-cosine signals. Mechanical alignment uses a 40 mm centering diameter, while the right-side cable exit helps in compact machine layouts. The rotor is balanced to standard quality, and the C motor length gives the unit a medium body within frame size 025. The standard housing also helps keep weight low for moving axes and supports installation in space-restricted sections of a machine.
Power and signal leads connect through a connecting cable with coupling unit, so the motor can be linked without opening a terminal box. The output uses a plain shaft, and a shaft seal helps keep coolant and dust away from the front bearing area. The drive end is supplied as a standard shaft end without a second shaft extension on side B, which keeps the output layout simple for couplings and pulleys. This single-ended arrangement leaves the rear section available for the integrated brake and feedback components, and it supports compact mounting where surrounding machine parts limit access.
