Product Description:

The MKD112B-073-GP0-AN is an AC servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Within an automated cell, the unit works with a drive controller to generate precise rotary motion so tooling heads, gantries, or transfer stations can follow programmed speed and position profiles. The synchronous design allows the drive to regulate speed and position with low lag during indexing, contouring, and point-to-point moves. By converting commanded current into proportional electromagnetic torque, it supports stable motion control for repeatable industrial processes in handling, packaging, and transfer applications.

This model supplies a continuous standstill torque of 28.0 Nm, allowing it to hold static loads without overheating when axis movement is paused. Installation uses a 130 mm centering diameter that aligns the stator housing in a register bore, while the square mounting face has a 192 mm flange size for standardized machine interfaces. Power and feedback cabling exit on Side A, and both circuits share a single output connector to simplify routing through crowded equipment layouts. That one-sided connection arrangement can help keep cable bends predictable near moving assemblies. The motor uses frame size 112 and length code B, which gives it a longer active stack for its housing size.

The motor is delivered without a holding brake, so an external locking device or drive torque must secure a vertical axis when power is removed. Rotor position is measured by resolver feedback (RSF), and the drive uses this analog signal for closed-loop control after startup. Because this feedback is relative, machine position is established by the control system during initialization. Drive torque is transmitted through a shaft with keyway, which supports keyed couplings used with pumps or gearboxes and helps resist slip during reversing loads. A positive shaft seal helps keep lubricants inside and contaminants out during operation.
