Product Description:

The MDD090A-N-020-N2M-130GB2 is an AC servo motor produced by Bosch Rexroth Indramat for use in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled stator current into precise mechanical rotation for indexing tables, packaging axes, and other automated stations that require repeatable velocity and position control. The unit belongs to the 090 frame range and is supplied in a standard housing for mounting inside protected machine enclosures.

The motor uses a centering diameter of 130 mm, which allows the flange to align concentrically with gearboxes or machine frames without additional shims. Power and feedback cables exit toward the rear because the connection hardware is located on Side B, which helps keep cables clear of moving mechanisms at the shaft end. A sealed connector set allows the motor to be disconnected without disturbing fixed machine wiring. During standstill, the stator can produce a continuous electromagnetic torque of 3.7 Nm, which helps support static loads without an external brake. Position data is provided by an integrated multiturn absolute encoder, allowing the drive to recover the rotor angle after a power cycle.

The built-in blocking brake adds 11.0 Nm of mechanical holding torque for vertical axes or other applications that require secure holding at rest. Within the MDD family, this model has the size designation 090 and length code A, giving it a compact profile that reaches up to 2000 rpm under rated bus voltage. Digital servo feedback channels the encoder data to the controller, while standard dynamic balancing helps keep vibration within normal limits. A shaft seal is fitted with the plain shaft to help limit dust ingress, and the housing is intended for cabinet-mounted installations.
