Product Description:

The MDD071B-N-060-N2S-095PB1 is a synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts commanded electrical input into controlled rotary motion for positioning axes, conveyors, and other automated machine functions. In servo applications, this supports accurate acceleration, speed regulation, and repeatable positioning during continuous operation. The motor suits compact installations that need quick response and stable torque output over frequent motion cycles.

The motor uses a centering shoulder diameter of 95 mm, which helps seat the housing accurately against a mating flange or gearbox register. Power and feedback connections are routed on Side B, and the unit uses a keyed connector so cable attachment remains compact and enclosed. At standstill, the motor can deliver a continuous torque of 4.4 Nm. Under rated conditions, it reaches a nominal speed of 6000 rpm, which suits low-inertia loads that require fast cycling and short response times. The B frame length provides the active motor length for this housing size, and the standard housing helps limit vibration transfer to adjacent machine parts.

A blocking brake on the non-drive side supplies 3.0 Nm of holding torque to keep an axis in place when power is removed. Position information is provided through digital servo feedback, allowing the drive to monitor rotor location during operation and maintain closed-loop control. The output shaft has a keyway and a shaft seal, which support positive torque transmission while helping limit contamination at the bearing area. The motor also uses standard balancing for smooth mechanical operation. Its single-ended shaft layout leaves no shaft extension on side B, which reduces overhung loading on the rear of the motor.
