MKD090B-058-KP1-KS
MKD Synchronous Motors
The MKD090B-058-KP1-KS is manufactured by Bosch Rexroth Indramat and forms part of the MKD Synchronous Motors series. This AC servo motor is built for closed-loop motion control in automated machinery, where it converts drive controller commands into precise shaft rotation. Typical uses include packaging axes, material handling stations, and machine-tool spindles that require steady torque and repeatable positioning.
The motor’s mechanical interface starts with a centering diameter of 110 mm, matched to a 140 mm square mounting flange so the stator seats accurately on gearboxes or adapter plates. Electrical and feedback leads exit on Side B, positioning the cabling away from moving machine elements. When the rotor is locked the unit can deliver 12.0 Nm of continuous standstill torque; this rating defines the thermal limit for sustained holding or low-speed feed motions. Winding code 058, motor length B, and the 090 frame size work together to balance power density against installation depth. A shaft with keyway transmits torque without relying on friction fits, and an internal shaft seal prevents lubricant migration toward the bearings.
To complement the mechanical ratings above, the integrated holding brake delivers 11 Nm of torque to clamp the shaft during emergency stops or power loss. Position data is gathered by a resolver feedback encoder that supports absolute position detection (>4096 revs), giving the drive controller multi-turn reference without homing cycles. The sealed connection box keeps field terminations protected from coolant splash, enabling straightforward installation. Together these features enable the MKD090B motor to maintain accuracy during idle periods and resume closed-loop control immediately after the brake is released.
