Product Description:

The MDD025B-N-100-N2K-040MD1 is a compact synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for integration with digital drive controllers, the unit delivers precise shaft rotation for pick-and-place heads, small rotary tables, and other high-speed axes found in automated assembly lines.

During continuous stall, the rotor sustains 0.60 Nm so position loops can hold load without overheating, while the winding design allows the shaft to reach a nominal speed of 10000 min⁻¹ for rapid indexing cycles. Electrical terminations face Side B, simplifying cable routing in tight cabinets, and the flange presents a centering diameter of 40 mm that mates directly to precision gearboxes. A blocking brake rated at 1.0 Nm secures vertical axes whenever power is removed, eliminating the need for external locking devices.

Standard dynamic balancing minimizes vibration across the 025 frame, and power enters through a connecting cable fitted with a coupling unit that matches the controller’s resolver interface. Position feedback is handled by Resolver feedback for real-time commutation, while an Integrated absolute encoder supplies multiturn position data to the PLC. The motor is built to length code B and incorporates a keyway shaft for positive drive coupling. A standard shaft end on the drive side is complemented by a rear that carries no secondary shaft, and the housing is produced in the series’ normal finish. For applications requiring low friction, the output comes without shaft seal, reducing drag in high-speed duty.
