Product Description:

The MKD112B-073-GG1-BN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As an electromechanical actuator, the unit translates commanded drive current into rotary motion for machine tools, packaging lines, and other automation axes that demand consistent torque and feedback-controlled positioning. Its internal resolver communicates rotor angle to the connected drive controller, allowing closed-loop speed and position regulation that supports tight process tolerances in continuous industrial service.

The motor delivers a continuous standstill torque of 28.0 Nm, ensuring the shaft can hold static loads without overheating when the machine is paused. An integrated brake supplies 22 Nm of counter-torque, so vertical axes remain secure when power is removed. Mechanical interface accuracy is aided by the 130 mm centering diameter, while mounting holes are placed on a 192 mm flange that matches standard gearbox patterns. Electrical power and feedback cabling leave on Side B through an output connector, keeping the opposite face clear for cooling air. The housing carries an IP65 rating, so dust and water jets will not reach internal windings during washdown cycles.

The motor uses F insulation class windings, allowing internal temperatures to rise well above ambient without degrading enamel life. It can be installed in production zones held between 0–40 °C, eliminating the need for separate climate conditioning. Position repeatability across one full revolution is limited to ±8 angular minutes, based on the resolver and relative detection method. A shaft seal blocks coolant spray from migrating along the plain steel shaft, preserving bearing grease during extended duty cycles. The 112 frame size and B length code give the motor a balanced aspect ratio that fits standard MKD housings while still providing sufficient rotor inertia for precise speed transitions.
