Product Description:
The MKD025B-144-GP1-KN servo motor is produced by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. Industrial automation platforms use this motor to generate controlled rotary motion for positioning tasks on packaging lines, material handling axes, and machining fixtures. The unit’s compact frame makes it suitable for tight multi-axis assemblies where high dynamic response and accurate feedback are required to synchronize tooling heads, indexing tables, or pick-and-place mechanisms.
The motor interfaces with the machine through a 54 mm mounting flange, so its stator housing seats directly against standardized gearheads or adapter plates without shims. Power and feedback wiring exit on the side B end because the terminals are grouped in a sealed connection box, simplifying service when modules are packed closely. At a 100% duty rating, the rotor can hold a continuous torque of 0.9 Nm while remaining within permissible winding temperature. Rotor position is derived from a resolver feedback (RSF) sensor, allowing sinusoidal commutation without relying on digital encoders. The flange combined with the low-inertia rotor provides rapid acceleration for small payloads and keeps settling times short during high-speed indexing.
Additional mechanical features secure the shaft and maintain alignment during stop-hold cycles. An integrated holding brake delivers 1 Nm of static torque, locking the rotor whenever control power is removed. Drive torque is transmitted through a shaft with a keyway, and a dedicated shaft seal prevents lubricant migration from adjacent gear stages. The MKD frame class of 025 and the medium motor length B balance torque density against overall weight, while relative position detection supports incremental homing routines on each startup. Thermal behavior and coil resistance are set by winding code 144, giving the motor electrical characteristics matched to compact Indramat drive modules.
