Product Description:

The Bosch Rexroth Indramat MDD093B-N-040-N5M-110GA1 is a synchronous motor in the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts command signals from drive electronics into precise rotary motion for positioning, packaging, and material-handling axes. This type of motor is suited for closed-loop motion tasks that require accurate speed control and repeatable positioning during frequent starts and stops. Because it works with digital drive controllers, commanded motion can be corrected in real time as load conditions change. The unit ships in a standard housing with standard rotor balance, so it can be mounted directly on machinery frames without extra vibration isolation.

At standstill, the motor sustains 14.5 Nm of continuous torque, so it can support steady load demand over long duty cycles. The rotor reaches a nominal speed of 4000 rpm, making it suitable for high-speed pick-and-place or spindle work. A centering shoulder of 110 mm aligns the flange with gearboxes and couplings. Position and velocity data reach the drive through digital servo feedback (DSF), enabling closed-loop regulation. This feedback arrangement helps the controller maintain commanded speed and position during acceleration, deceleration, and load changes. Power, signal, and brake leads exit toward Side A, which helps keep cable routing consistent when multiple motors share a common tray. The rotor and fan use standard balancing, and a factory shaft seal helps keep dust and spray out of the interior.

An integrated blocking brake delivers 11 Nm of holding torque to prevent back-driving when the amplifier is disabled. All electrical terminations are made through a keyed connector, allowing secure connection without disturbing adjacent circuits. Torque is transmitted by a plain shaft, which avoids keyway-related stress concentrations in servo gear trains. An integrated multiturn absolute encoder preserves the position reference across power cycles, so homing moves are not required after startup. The motor length code B and size 093 provide a compact footprint, and natural convection cooling is supported by the standard housing for repetitive motion sequences.
