Product Description:

The MDD090B-N-040-N2M-130PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive current into regulated mechanical rotation. When paired with a compatible controller, it supports precise positioning and stable speed control in automated machinery. The synchronous design also helps the drive maintain consistent motion during frequent starts, stops, and reversals on automated axes.

At standstill the motor supplies a continuous torque of 7.2 Nm, which is the load it can hold without overheating when shaft speed is zero. During normal operation it reaches a nominal speed of 4000 rpm, allowing compact axes to achieve rapid traverse rates. Accurate rotor position is returned through an integrated multiturn absolute encoder, and digital servo feedback (DSF) gives the controller the data needed for closed-loop regulation. This feedback arrangement preserves position information across multiple revolutions and supports repeatable motion after a restart. Mechanical alignment to machine frames is simplified by a centering seat of 130 mm. The rotor is balanced to the standard grade to help limit vibration at high speed, and motor length code B provides the thermal capacity needed for its output rating.

In installation areas, wiring exits the stator on the Side B through a keyed connector, which helps keep cable routing clear of adjacent modules. A blocking brake is integrated and develops 6.5 Nm of holding torque to secure vertical loads when the drive is de-energized. A shaft seal is fitted to protect internal bearings from coolant or dust, and the keyway shaft supports positive torque transmission to the driven element. Motor size 090 keeps the external diameter compact while still accommodating the specified stator stack. This arrangement suits applications that need sealed shaft protection, orderly cable entry, and holding torque when power is removed.
