Product Description:
The MDD093B-N-020-N2M-130GA1 synchronous motor is built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed as a drive element for digital servo controllers, it converts controlled current into rotary motion for medium-inertia machine axes in printing, material handling, and general automation. This operating role supports accurate acceleration, deceleration, and speed regulation in equipment that must repeat the same motion profile over long production runs. The motor uses the B length code and a size 093 frame, has a standard housing, and keeps the side-B shaft end closed. Internal dynamic balancing keeps vibration within normal limits for direct coupling to precision gearboxes or belt transmissions.
A centering diameter of 130 mm positions the flange concentrically, and the power and feedback plugs are located on side A so cable routing stays on one machine face. The electrical interface uses a keyed connector, which allows secure attachment of the mating cables. At standstill, the motor can supply 14.5 Nm of continuous torque while remaining within its thermal limits, and its rotor is optimized for a nominal speed of 2000 rpm. This combination suits moderate-speed axes that need steady torque without excessive heating during normal operation. A standard shaft seal protects the front bearing against coolant or dust ingress.
The built-in integrated multi-turn absolute encoder reports absolute rotor angle over multiple revolutions, while the drive reads it through digital servo feedback (DSF) lines for closed-loop control. Because position data remains available across revolutions, the controller can identify shaft position immediately after power-up. For holding loads when power is off, a blocking brake delivers 11 Nm of static torque and is released through the controller's 24 V circuit. The motor uses a plain shaft, so torque is transmitted by friction couplings or clamp-style hubs rather than a keyway.
