Product Description:

The MKD090B-046-KG1-KN belongs to the MKD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a servo motor for precision positioning and velocity control in automated machinery, where closed-loop feedback supports coordinated motion between mechanical axes and the drive system. That control method helps the axis maintain commanded speed and position as load conditions change during normal machine cycles. The motor uses a plain shaft with a shaft seal, so it can connect to external couplings while helping keep lubricant inside the housing.

This model delivers a continuous standstill torque of 12.0 Nm, so it can hold or slowly index loads without overheating while the shaft is stalled. It has a flange size of 140 mm and a centering pilot of 110 mm, which helps keep the motor aligned on common mounting faces. This mounting geometry supports accurate alignment with gearboxes and machine plates and helps reduce coupling stress during operation. The housing is rated IP65, which helps protect internal parts from dust and low-pressure water jets in industrial areas. Position repeatability is supported by a system precision of ±8 angular minutes, which is the maximum deviation between the commanded and actual shaft angle under normal load.

A holding brake rated at 11 Nm maintains shaft position when power is removed, which is useful on vertical axes and during stop conditions. Rotor angle is returned to the drive through resolver feedback, and absolute multiturn tracking beyond 4096 revolutions allows operation without homing after a power cycle. Cabling enters from Side B through a sealed connection box, and this arrangement helps keep the terminals protected and away from nearby moving equipment. The motor is intended for ambient temperatures from 0–40 °C. The insulation class F winding uses code 046, and it is installed in a B-length 090-frame package that is compatible with standard industrial inverters.
