MDD025B-N-100-N2G-040GR1
The MDD025B-N-100-N2G-040GR1 is a small-frame synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, the unit converts commanded current into rotary motion for light-duty positioning axes and high-speed spindles in automated machinery. The motor fits installations where limited mass and high base speed are important, and its blocking brake lets the load remain fixed when power is removed. This compact format helps reduce moving mass on small slides and rotary units where motor weight affects response and settling time.
In continuous operation, the motor delivers 0.60 Nm of torque at standstill, giving steady torque for static tensioning or slow-speed creep without overheating. Once energized, its rotor can reach a rated speed of 10000 rpm, allowing short cycle times on compact pick-and-place heads or miniature grinders. A blocking brake integrated at the non-drive end supplies 1.0 Nm of holding torque so vertical loads remain locked during power loss. Position data is returned through resolver feedback, which provides analog sine-cosine signals suitable for commutation and stable operation across changing temperatures. All power and feedback conductors exit on the right side, which simplifies cable routing when multiple motors share the same wiring plane.
Mechanical alignment is centered by a 40 mm pilot diameter, and the winding end bell carries a keyed connector that accepts standard MDD cabling for a secure electrical connection. The drive shaft is a plain shaft without secondary machining, reducing runout when coupled through collets or clamp hubs, and a dedicated shaft seal surrounds the journal to limit lubricant migration into the stator. Standard balancing limits residual vibration, while the B-length stator core and size-025 frame keep overall inertia low so the motor can respond quickly to drive commands without excessive torsional overshoot.
