Product Description:

The MDD065B-N-040-N2M-095PR0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers in closed-loop motion systems. The motor converts commanded current from the inverter into mechanical rotation for positioning and speed-regulated tasks on packaging lines, pick-and-place gantries, and small conveyor axes in industrial automation. Its operating role suits machines that require repeatable motion and responsive speed control during short-cycle production.

The motor body belongs to size code 065 and length code B, creating a compact profile that seats against a centering flange of 95 mm diameter. At its rated electrical frequency, the rotor can maintain a nominal speed of 4000 rpm, while a continuous standstill torque of 1.5 Nm is available for static holding or slow-speed feed motions. Positional data is returned through an integrated multiturn absolute encoder that works with the drive’s digital servo feedback channel, allowing closed-loop control without external resolvers. Standard dynamic balancing limits vibration transmitted to adjacent machine parts, and the cast housing uses the standard version for normal protection and heat dissipation.

Electrical and feedback terminations exit on the right side through a keyed connector, which can simplify cable routing inside tight cabinets. The shaft has a ground keyway for direct coupling, and a factory-installed shaft seal helps protect the front bearing from lubricant washout and airborne particles. Because the unit is supplied without a blocking brake, holding force must come from the drive or an external clamp when power is removed. The motor uses a single-ended shaft without a side-B extension, which helps keep inertia low for fast directional changes.
