Product Description:
The MKD071B-035-KG1-KS is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. In factory automation, the unit converts drive controller current into mechanical rotation for positioning axes that demand repeatable accuracy and fast cycle times. The motor has size 071 and length code B, giving a compact form suited for mid-range loads. A built-in holding brake permits secure standstill during power loss, while its plain shaft allows direct coupling to gearboxes or machine elements. This motor type is commonly paired with a closed-loop drive so acceleration, deceleration, and holding behavior remain controlled during repeated indexing moves.
At the mounting interface, the centering diameter is 95 mm, and the square flange measures 115 mm; these dimensions align the stator precisely on standard machinery frames. During continuous standstill, the motor can deliver 8.0 Nm of torque, which marks its thermal limit while locked and energized. Position data is generated by a resolver feedback system with an integrated encoder, enabling absolute detection beyond 4096 revolutions for coordinated multi-axis motion. Electrical behavior follows winding code 035, which matches the resistance and inductance values expected by compatible Rexroth drive amplifiers. Power and feedback conductors exit on Side B through a sealed connection box, which keeps the motor terminals enclosed and helps simplify cabinet routing.
The integral holding brake supplies 5 Nm of static torque to secure vertical loads without drive current. External dust and water jets are blocked by the IP65 housing and an additional shaft seal, making the unit suitable for washdown areas within its permissible ambient range of 0–40 °C. Insulation class F supports winding temperatures up to 155 °C, and overall system precision remains within ±8 angular minutes, so closed-loop controllers can maintain tight positional tolerances. This arrangement helps protect internal components when the motor is installed on exposed machine sections. The sealed connection box also safeguards terminals against accidental contact during normal operation.
