Product Description:

The MKD112B-073-GP0-BN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. Designed for closed-loop drive systems, the unit converts electrical input from an inverter into controlled rotary motion for positioning, feeding, or indexing tasks on automated lines. The motor integrates with digital controllers used in packaging, material-handling, and machining cells where precise torque and speed regulation are required to synchronize multi-axis equipment.

Its centering pilot measures 130 mm, a dimension that positions the stator concentrically to the driven machine frame and minimizes radial runout. The square mounting flange spans 192 mm, establishing a standard bolt pattern used on size-112 synchronous motors. Under steady-state operation, the electromagnetic circuit delivers 28.0 Nm of continuous stall torque, allowing constant load holding without thermal overload. Power and feedback cables terminate on an output connector, reducing wiring time during installation or service. Rotor position is monitored through resolver feedback (RSF), providing noise-immune analog sine-cosine signals for the drive to calculate instantaneous angle and velocity.

All electrical interfaces are oriented toward Side B, keeping conductors clear of moving tooling when the motor is mounted on gantries or presses. The drive interprets shaft rotation in a relative reference frame, so homing routines establish an application-specific zero at startup. The motor operates without a holding brake, so static position retention must rely on controller torque or external locks. The motor uses a shaft with keyway to transmit torque without slippage under peak loads. A radial lip seal is installed at the bearing journal to keep lubricant in and contaminants out, and the Size 112 frame paired with Motor Length B offers a compact envelope suited to medium-inertia axes.
