MDD071B-N-030-N2G-095PB0
The MDD071B-N-030-N2G-095PB0 is a motor for digital drive controllers manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. This permanent-magnet synchronous motor converts regulated output from a matching drive into precise rotary motion for packaging, conveyor, and machining axes. It is suited for closed-loop positioning and speed control where smooth response and repeatable movement are required. Because the drive regulates commutation and current in real time, the motor can support synchronized axis motion in machines that require accurate starts, stops, and speed changes. Its compact frame supports direct installation in multi-axis assemblies without the need for intermediate transmission stages.
A centering pilot of 95 mm aligns the motor accurately with the machine flange. Power and feedback conductors exit on side B through a keyed connector, which keeps cable routing on the non-drive end of the axis and helps reduce interference with couplings or tooling. That layout also simplifies access around the rear of the motor when the face is mounted directly to a machine plate. The motor provides a continuous torque rating of 4.4 Nm and reaches a nominal speed of 3000 rpm during normal operation. The motor uses the standard housing and motor length B, and it is supplied without a blocking brake so the shaft turns without brake drag when power is removed. Standard rotor balancing helps limit vibration during repeated high-speed cycles.
Position information is returned to the drive through resolver feedback, allowing stable current regulation during acceleration and load changes. Resolver-based feedback also remains practical in applications that experience electrical noise or frequent speed changes. The output shaft uses a keyway for secure torque transmission, and it is equipped with a shaft seal to help keep lubricant and contaminants away from the bearing area. Motor geometry follows size code 071, which keeps the frame compatible with related components in the same size class. The shaft end on side B is omitted, leaving more clearance near the rear of the housing for compact machine layouts. This arrangement is useful where guards, cable bends, or adjacent drive elements must fit close to the motor.
