Product Description:
The MKD112B-024-KG1-RN belongs to the MKD Synchronous Motors series from Bosch Rexroth Indramat and serves as a servo actuator for coordinated motion in automated machinery. It uses the 112 frame class with compact length code B and class F insulation, so the windings can handle elevated operating temperatures during cyclic duty. In servo systems, the motor converts controlled electrical input into rotary motion for accurate speed and position regulation on machine axes. It is suited to axes that must start, stop, and reverse with controlled response under drive supervision. Its overall format suits installations that need substantial output without requiring an oversized mounting envelope.
The motor mounts to a machine wall by a 192 mm flange, and the pilot uses a 130 mm locating diameter for repeatable concentricity. A plain shaft transmits torque directly to the load, and a shaft seal helps limit ingress at the rotary interface. Electrical power enters through a right-side power connector, which simplifies cable routing when the connection direction is right. The enclosure is rated IP65, protecting internal components from dust and low-pressure water jets. For continuous positioning tasks, the motor can provide up to 28.0 Nm of standstill torque under thermal equilibrium conditions. The stator uses winding code 024, which corresponds to the electrical values expected by compatible drive controllers. The sealed housing supports use in machine areas where dust or light washdown exposure may occur.
Position feedback is provided by resolver electronics with an integrated encoder, and the system provides absolute (>4096 revs) position detection, allowing immediate position availability after power-up. During motion, the rotor maintains a precision window of ±8 angular minutes, which supports tight closed-loop control. A holding brake rated at 22 Nm secures the axis when power is removed, helping prevent drift on vertical or suspended loads. The assembly operates within a 0–40 °C ambient range, which matches typical factory and control-cabinet conditions. This feedback arrangement is useful on axes that need to resume operation quickly after planned stops or brief power interruptions.
