Product Description:
The MKD071B-061-PG1-UN belongs to the MKD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a servo motor intended for closed-loop positioning and speed regulation in automated machine axes, packaging lines, and handling modules. By combining permanent-magnet excitation with digital feedback, the unit converts drive current into controlled rotary motion and supplies repeatable torque within the standardized 071 frame outline.
The motor seats against a machinery wall through a 115 mm square flange and centers accurately on a 95 mm pilot, ensuring coaxial alignment with gearboxes or pulleys. Its continuous torque capability is 8.0 Nm at standstill, so the shaft can hold load without overheating when the inverter maintains rated current. Power and encoder connectors are mounted on a housing that can be rotated up to 270°, allowing cable exits to be adjusted after the motor is fixed. Once wired, the housing meets the IP65 ingress rating; dust penetration is prevented and water jets will not affect the windings or feedback electronics. A plain steel shaft transmits motion directly, and a factory-installed shaft seal blocks oil splash from migrating into the front bearing. Size code 071 and length code B indicate the active stack height, giving a mid-range inertia class for moderate acceleration profiles.
An integral holding brake supplies 5 Nm of static torque to keep vertical or suspended loads in position whenever power is removed. The windings follow Class F insulation rules, permitting internal hot-spot temperatures up to 155 °C during cyclic duty. Thermal sensors help the drive protect the stator when the motor operates in ambient temperatures from 0–40 °C, so cabinet ventilation can be sized accordingly. Coil set designation 061 indicates resistance and inductance values that match Indramat supply modules; this pairing minimizes current ripple and maintains smooth velocity during rapid index moves.
