Product Description:

The MKD090B-035-GP0-KN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. As an electrically commutated unit, it supplies controlled rotary motion to axes that demand accurate speed and position regulation within automated equipment found on assembly, packaging, and machining lines.

The motor’s continuous stall capability is rated at 12.0 Nm, indicating the steady torque it can deliver without overheating when the shaft is locked. Mechanical fit-up to a machine frame is defined by a centering diameter of 110 mm and a square mounting flange that measures 140 mm across, ensuring repeatable alignment against gearboxes or direct-drive couplings. Cables are introduced through a connection box that sits on Side B of the housing, so cabinet routing can be planned around this fixed outlet. The “B” length code balances rotor inertia against thermal mass, while the “090” frame size groups the motor with other mid-range diameters in the series. Together, these geometric parameters help engineers predict load matching and envelope clearance during installation.

Feedback and mechanical linkage details complete the performance profile. Rotor position is measured by a resolver feedback (RSF) element, and its data stream supports Relative position detection routines inside the controller. Power is transferred through a shaft with keyway, giving a positive drive interface for couplings or pulleys without relying on friction alone. Winding design is identified by code 035, which pairs the stator resistance and inductance to drive inverters sized for this specific electromagnetic load. When combined with the previously noted mounting and torque parameters, these electrical and mechanical attributes allow predictable axis tuning without iteration.
