Product Description:

The MKD090B-047-KP0-KS is a servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It is intended for closed-loop industrial automation where accurate rotary positioning and repeatable speed control are required to synchronize mechanical axes and keep process motion consistent. The motor converts electrical drive commands into controlled rotary motion for indexing tables, feed axes, and other automated machine functions that require consistent response. Winding code 047 identifies the electrical design used with compatible Indramat drives, while the B motor length indicates a mid-length stack. Insulation class F allows winding temperatures up to 155 °C during cyclic duty.

This motor delivers a continuous standstill torque of 12.0 Nm, providing sustained drive force for holding or slowly moving loads without overheating. Installation uses a centering diameter of 110 mm and a square flange that measures 140 mm, so the housing fits common machine interfaces and supports accurate alignment on the machine face. Power and feedback conductors enter through a connection box mounted on side B of the stator, which helps cable routing when space behind the shaft is limited. The shaft has a keyway for direct torque transfer, and the motor is supplied without a holding brake, so static load retention must be handled by the drive controller or external mechanics.

The housing is sealed to IP65, and a shaft seal helps prevent oil or coolant from entering along the journal during normal machine operation. System precision is specified at ±8 angular minutes, which supports accurate axis alignment in positioning tasks. The feedback system supports absolute position detection beyond 4,096 revolutions through integrated Resolver feedback. The permissible ambient temperature range is 0–40 °C, which matches typical shop-floor conditions, and size 090 uses the standard frame diameter used across this motor family.
