Product Description:

The MDD071B-N-040-N2S-095PB0 synchronous servo motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts inverter output into controlled rotary motion for positioning tasks in automated machinery. Its compact build suits mid-range axes that require repeatable movement and stable response during frequent start-stop cycles. Used with a compatible drive, the motor supports controlled acceleration, deceleration, and holding behavior during normal servo operation. This makes it suitable for equipment such as indexing systems, transfer units, and automated handling machines.

The mechanical interface includes a centering diameter of 95 mm, which helps locate the housing accurately in a machine flange, and the motor uses standard balancing for general industrial service. Continuous torque at standstill reaches 4.4 Nm, providing holding force until the axis is commanded to move. The rotor can run at up to 4000 rpm, giving the drive a wide operating speed range for positioning and feed applications. Position and velocity are closed through digital servo feedback (DSF), so the controller receives encoder data with low delay. This arrangement helps the drive maintain accurate speed and position regulation during repetitive motion. Power and feedback conductors connect through a top-mounted connector, which helps keep cable routing orderly above the motor. The motor uses length code B, which corresponds to the stack length used for this torque class.

Cables exit on side B, which keeps the connection point on one face of the motor housing. The size code 071 identifies the frame used for this model within the MDD range. The motor is supplied without a blocking brake, so any holding function during power-off conditions must come from the drive or an external device. The shaft uses a keyway for positive torque transfer and includes a shaft seal to limit the entry of dust or fluid at the bearing area. The housing and shaft end use standard forms, and the motor operates without auxiliary cooling hardware.
