Product Description:

The MDD093A-N-040-N2M-110PB0 is a motor for digital drive controllers manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It provides commanded torque and velocity to industrial axes that require tight position control in assembly cells, packaging lines, and metal-cutting machines. The design belongs to the 093 frame class, and its A-length stack keeps overall depth low for compact machine layouts. Its synchronous design allows the paired controller to regulate speed and position with predictable response during repeated motion cycles.

The motor delivers a continuous standstill torque of 9.2 Nm and has a nominal speed of 4000 rpm. Standard rotor balancing minimizes vibration, while the centering diameter of 110 mm supports concentric mounting against gearboxes or flange plates. Power and feedback conductors exit through a sealed connector on side B of the stator, which helps route cables away from rotating parts. A standard housing dissipates heat to ambient air, and the built-in shaft seal helps keep coolant splashes out of the bearing region. This arrangement suits machine locations where splashed fluids or airborne debris may reach the motor housing.

Closed-loop regulation is supported by digital servo feedback (DSF), which transmits position data from an integrated multi-turn absolute encoder to the drive controller. The encoder retains position information across multiple revolutions, which supports axes that need absolute reference data after restart. Because the unit is supplied without a blocking brake, any static holding duty must be managed by the drive or an external clamp. The motor uses a single keyway shaft to transmit torque to couplings. The opposite end has no auxiliary output, which helps maintain a narrow footprint while allowing simple axial sealing.
