Product Description:

The MKD090B-035-KP0-KN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a permanent-magnet AC unit, it works with digital drive controllers to generate closed-loop motion in packaging lines, pick-and-place axes, and forming machines. The motor converts electrical energy from the drive into regulated rotary torque, allowing precise positioning and repeatable speed control during cyclic machine operation. This supports indexing, transfer, and synchronized positioning tasks in automated equipment.

A centering pilot of 110 mm aligns the flange precisely on the machine casting, while the square mounting interface spans 140 mm. This layout helps keep the motor seated accurately during acceleration and reduces the chance of radial misalignment that can increase bearing load. The mounting geometry also helps preserve coupling alignment during repeated start-stop cycles. When energized, the motor delivers a continuous standstill torque of 12.0 Nm, which supports axes that must hold position against process resistance or static load. Electrical terminations and feedback lines leave from Side B and pass through a sealed connection box, which keeps cable routing organized and supports strain relief at the housing.

Rotor position is monitored by resolver feedback integrated behind the stator windings, and the sensor supplies sine-cosine signals for phase commutation and position tracking. The feedback system also provides absolute (>4096 revs) information, so the controller can retain position data through many shaft turns without relying on mechanical reference switches. Magnetic and thermal characteristics correspond to winding code 035, so the matching drive must use the electrical values associated with that winding. Mechanical output is delivered through a shaft with keyway, allowing positive torque transmission to pulleys or gearboxes while the shaft seal helps separate lubricants and contaminants. The keyed connection also helps prevent slip when torque reverses during rapid direction changes.
