Product Description:
The MDD071C-N-040-N2T-095PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it receives modulated three-phase current and delivers controlled shaft rotation for indexers, pick-and-place axes, and packaging equipment. Its mechanical and feedback features allow the drive to close the velocity and position loops directly on the motor, improving dynamic accuracy in industrial automation. Because feedback is integrated into the motor, the connected drive can monitor rotor motion without separate external sensing hardware on the axis. This arrangement supports controlled starts, stops, and repeatable positioning during rapid machine cycles.
At standstill, the rotor can provide a continuous torque of 6.6 Nm, which indicates the load the axis can hold without thermal overload. Under rated excitation, the motor reaches a nominal speed of 4000 rpm, so servo drives can achieve fast traverses while maintaining field-oriented control. Accurate mechanical seating is helped by a centering diameter of 95 mm that matches standard machine mounting flanges and keeps the housing aligned during installation. Position and speed signals are returned through digital servo feedback (DSF), which comes from the integrated multi-turn absolute encoder and allows the controller to read the shaft angle after power cycles. The multi-turn encoder retains positional reference across multiple revolutions, which is useful on axes that cannot be re-homed after every power cycle. Torque is transmitted through a keyway shaft for positive coupling to pulleys or gearheads. Standard rotor balancing, housing style, length code C, and size 071 complete the electromechanical envelope, while the standard shaft end omits a side-B extension to reduce installation depth.
A blocking brake is fitted and delivers 3.0 Nm of static holding force. It secures vertical loads when the drive is de-energized. Power and feedback lines are terminated through a connector that exits to the left, simplifying cable runs in multi-axis cabinets. The shaft is protected by a shaft seal, which helps limit contamination in dirty operating areas.
