Product Description:

The MKD090B-058-KP1-KS servo motor is manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It serves as an electromechanical drive element that converts command signals from digital controllers into controlled rotary motion for automated machinery. Resolver feedback with an integrated encoder supplies absolute position data that remains valid for more than 4096 revolutions, supporting accurate homing after power cycles. Because the housing is fully sealed, the motor suits oil-mist or dust-laden factory environments. It is also well suited for positioning, transfer, and feed axes where repeatable motion is required during normal machine cycles.

A centering pilot of 110 mm aligns the motor to the mating register, and a flange size of 140 mm sets the mounting bolt pattern. During sustained stall conditions, the motor can deliver 12.0 Nm of torque without exceeding thermal limits, which supports static load holding at zero speed. System accuracy is held to ±8 angular minutes, limiting positional deviation between the commanded and actual shaft angle under closed-loop control. The housing has an IP65 rating, which helps protect internal windings and bearings from airborne particles and low-pressure water jets when the connection box is mounted on side B of the frame.

The integrated brake provides 11 Nm of holding torque when the drive is disabled, and Class F insulation permits continuous winding temperatures up to 155 °C. Operation is permitted in ambient temperatures from 0–40 °C without derating, and the keyed shaft includes a shaft seal that helps prevent lubricant migration along the journal. Winding code 058 identifies the electrical winding used in this size-090, length-B motor. The absolute feedback arrangement lets the controller retain position information across restart events, and the brake helps keep the axis stationary when power is removed.
