Product Description:

The MDD093C-N-020-N2M-130GA2 synchronous motor is produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical power from the servo amplifier into controlled rotary motion for positioning, conveying, and tooling axes in automated systems. Its design uses a permanent-magnet rotor and stator windings sized for medium-frame applications, helping the motor deliver accurate speed and torque response. It is intended for motion tasks that require repeatable positioning and stable servo behavior through changing load conditions. The motor is suited to automated equipment that depends on smooth acceleration and controlled stopping.

An internal blocking brake delivers 22 Nm of static torque, letting the axis stay fixed when power is removed or an emergency stop is issued. During operation, the rotor reaches a nominal speed of 2000 rpm, which suits many industrial servo axes that need a steady base speed for regular production cycles. Position and velocity loops are closed through digital servo feedback (DSF), while the motor's integrated multi-turn absolute encoder reports the shaft angle over multiple revolutions without battery backup. Power and feedback conductors exit on side A of the housing, which can simplify cable routing when the flange faces the machine frame.

Mechanical alignment is aided by a centering pilot of 130 mm, which helps the motor seat accurately against the mounting surface. A keyed industrial connector carries phase current, brake supply, and signal leads to the drive, reducing the need for separate connection points at the housing. Contaminant ingress at the front bearing is limited by a shaft seal, and the smooth plain shaft end avoids the stress concentration that can come with a keyed shaft. This arrangement also keeps the output end suitable for couplings that clamp directly to the shaft surface. The C-length housing and size 093 frame give the motor a moderate installation envelope for general machine layouts where compact mounting and direct coupling are important.
