Product Description:
The MKD090B-085-KG1-AN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. By converting drive current into controlled rotary motion, the motor serves as the prime mover for numerically controlled tables, material-handling stations, and other automated equipment that needs repeatable position and velocity profiles. Its electromagnetic rotor pairs with platform-matched drives, allowing closed-loop motion without external gear reduction. This arrangement supports precise acceleration, steady running speed, and repeatable stopping points in automated axes.
At standstill, the motor can supply a continuous torque of 12.0 Nm, enabling static load support without overheating. The motor has a 140 mm square flange and a 110 mm centering diameter, which fit common machine mounting faces and help maintain alignment. The permitted ambient temperature range is 0 to 40 °C; outside this range, derating is required. The winding insulation is class F, and the cast housing carries an IP65 rating so dust and water jets are kept away from internal components. Position feedback comes from a resolver feedback system integrated with the rotor, allowing the drive controller to monitor shaft position during operation.
A factory-mounted holding brake supplies 11 Nm of static torque to lock the shaft when power is removed, which is useful on vertical axes. Motion accuracy in closed-loop operation is supported by a system precision of ±8 angular minutes, while embedded electronics support absolute position tracking beyond 4096 revolutions. The motor uses a plain shaft with a shaft seal to help prevent lubricant migration at the output end. Electrical power is routed through an output connector on Side A of the housing, which can simplify cable routing in some mounting positions. The motor has size code 090 and length code B, giving it an active stack height that keeps inertia moderate for dynamic cycles.
