Product Description:
The MKD071B-035-EG1-KN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. This AC servo unit combines electronic commutation with a permanent-magnet rotor to deliver closed-loop motion control for indexing tables, packaging axes, and general factory automation. By converting drive current into rotational torque with high-resolution feedback, the motor allows precise positioning and repeatable speed profiles in multi-axis production cells.
The centering diameter of 95 mm seats the stator housing accurately inside the machine register and keeps runout within alignment limits. A flange face measuring 115 mm follows the IEC square pattern, so the motor bolts directly to standard gearboxes or mounting plates. When energized, it can supply 8.0 Nm of continuous standstill torque, allowing stable load support without forced cooling. Power and encoder conductors leave on Side B, and the sealed connection box protects terminations from dust and coolant splash. Winding code 035 indicates the copper fill factor and resistance used with compatible Rexroth drive controllers. A plain shaft with a factory-installed seal prevents lubricant escape while transmitting torque to couplings or belt pulleys.
Dynamic engagement is handled by an integral holding brake that clamps the rotor with 5 Nm of torque during power-off states. The aluminum housing carries an IP65 rating, allowing installation in washdown areas where low-pressure water jets are present. Class F insulation tolerates winding temperatures up to 155 °C, supporting cyclical overloads without premature aging. Thermal limits are also governed by a permissible ambient range of 0 to 40 °C, helping preserve insulation life when the motor is mounted inside enclosed cabinets. Size code 071 and length code B keep the overall package compact for medium-inertia axes.
