Product Description:
The MKD090B-035-KP1-KN synchronous servo motor is manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. Within an automation cell, it couples to a drive controller to deliver programmable speed, position, and torque, supplying the mechanical output required to index conveyors, rotate tooling, or coordinate multi-axis assemblies. Its electromagnetic design allows rapid acceleration while maintaining precise feedback, making it a typical choice for applications that require coordinated motion profiles and high repeatability. It is well suited to equipment that runs repeated motion cycles and depends on stable closed-loop response throughout normal operation.
The motor generates a continuous standstill torque of 12.0 Nm, giving it sufficient holding capability for loads that must remain stationary without overheating. A centering pilot of 110 mm aligns the housing concentrically with the machine frame, and the square flange measures 140 mm across for ISO-standard mounting patterns. Electrical power and resolver cabling leave the unit at the rear because the connections are oriented toward Side B and terminate in a rugged connection box that protects the terminals against vibration and contamination. These dimensions support consistent installation and predictable heat flow from the stator to the mounting surface. The rear-facing cable arrangement can also help keep wiring clear of couplings, rotating parts, and surrounding machine hardware.
The integral brake supplies 11 Nm of static torque to hold vertical axes when power is removed, and a shaft seal helps prevent coolant mist from entering during washdown cycles. Rotor position is measured by resolver feedback, and the feedback system supports Absolute (>4096 revs) position tracking so the drive retains position after power cycling. Magnetic characteristics follow winding code 035, matching the motor to the appropriate current and voltage range used by compatible drive systems. A keyed shaft transmits torque positively, and the motor uses size 090 with length code B for a balanced combination of inertia and torque density in mid-range applications. This arrangement supports axes that must move accurately during production and remain secure between motion cycles.
