Product Description:
The MKD112B-058-GP0-BN belongs to the MKD Synchronous Motors series from Bosch Rexroth Indramat. It is a servo motor intended for closed-loop position and speed control in automated handling, packaging, and forming lines where repeatable motion is required. The motor works with compatible digital drives to convert commanded current into controlled shaft motion. This arrangement supports smooth acceleration, deceleration, and positioning on axes that must follow changing production commands. Because it is supplied without a holding brake, external mechanical locking or drive torque must keep the load stationary during power-off conditions.
At standstill, the motor can deliver a continuous torque of 28.0 Nm, which indicates the load it can support continuously while staying within its rated temperature range. The mounting interface uses a 192 mm square flange, so machine frames need a matching bolt pattern to secure the housing. Radial alignment during installation is guided by the 130 mm centering diameter, and this seating surface helps minimize runout between the motor shaft and coupled mechanics. Electrical and thermal behavior follow winding code 058, which corresponds to the resistance and inductance values used by the matched drive. Power and feedback conductors exit on Side B, allowing cable routing toward the rear of typical cabinet layouts.
The interface to the drive controller is a single output connector that carries phase power and signal lines, reducing panel space compared with separate plugs. Using one connector also helps simplify cable routing where space around the motor is limited. Mechanical power is transferred through a shaft with keyway, giving positive engagement to pulleys or couplings without relying on friction alone. Rotor position is reported by resolver feedback, so the controller performs a reference move after power-up before absolute positioning begins. A shaft seal helps limit dust or oil ingress at the coupling interface, and the motor uses size code 112 with length code B to keep the housing compact for applications that need moderate torque in a limited installation space.
