Product Description:

The MDD090A-N-020-N2M-130PB1 is manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts commanded current into precise rotary motion for packaging lines, gantry axes, and similar automated equipment. The motor uses a size 090 frame with A length, standard balancing, and a standard shaft end so it fits compact machine layouts. It is suited to closed-loop motion tasks where the drive must regulate speed and position with repeatable response under changing loads. The compact housing also helps when the motor is mounted beside guards, gearboxes, or transfer hardware with limited clearance.

At a nominal speed of 2000 rpm, the rotor tracks the commanded drive frequency while staying within thermal limits. During standstill, it can generate 3.7 Nm continuously, which supports static loads during indexing moves. Position data comes from an integrated multiturn absolute encoder, and it is transmitted through digital servo feedback so the controller receives position information after power cycles. A 130 mm centering diameter aligns the flange with gearboxes or mounting plates to limit radial runout. Because the feedback system retains absolute position over multiple revolutions, many machines can restart without a reference move, which reduces unnecessary axis travel after a shutdown.

A factory-installed blocking brake provides 6.5 Nm of holding torque to resist back-driving when the inverter is disabled. A shaft seal sits behind the flange to help keep coolant and dust out of the bearing cavity, and the keyway shaft transfers torque without relying only on clamping friction. The cable outlet on Side B keeps the connection area away from the driven end, which leaves more space for couplings and guarding. Rear cable routing can also reduce cable bend near the coupling area when the machine design places the driven element close to the motor face. The brake can hold the axis at rest when power is removed, and the protected shaft area helps support reliable operation in industrial environments.
