Description
Bosch Rexroth MKD071B-061-KG1-KN
Technical Specifications MKD071 frame size; permanent magnet synchronous motor; resolver feedback; built-in holding brake; 400V three-phase winding; flange mounting; IP65 protection rating; smooth output shaft; rated speed and torque for medium dynamic load.
Functional Features Medium torque density with compact mechanical outline; resolver feedback resistant to mechanical shock and vibration; integrated holding brake for static shaft locking; low cogging torque ensures steady low-speed operation; high peak overload torque handles transient load spikes; optimized housing heat dissipation structure.
Application Scenarios Packaging machine main servo axis; textile machinery traverse drive; printing machine register control axis; CNC auxiliary feed axis; automated material handling small gantry axis.
Performance Parameters Operating ambient temperature -20℃ to +40℃; storage temperature -40℃ to +85℃; relative humidity 5% to 90%, no condensation; insulation class F.
Material Composition Aluminum alloy housing; silicon steel laminated stator; rare-earth permanent magnet rotor; copper insulated winding; stainless steel output shaft; polyurethane shaft seal; metal resolver assembly; brake friction plate and coil assembly.
Structural Characteristics Cylindrical motor body with standard front flange; rear resolver feedback unit; built-in electromagnetic brake module; side mounted cable terminal box; shaft lip seal for dust and water protection.
Working Principle Servo drive outputs three-phase variable frequency alternating current to stator winding and creates rotating magnetic field. Permanent magnet rotor rotates under magnetic torque. Resolver sensor captures rotor angle and sends feedback signal to servo drive for closed-loop control. When power supply disconnects, brake coil de-energizes and friction disc locks output shaft.
Installation Requirements Mount motor flange rigidly on machine frame. Install shielded power and resolver cables separately, separate power cable from low signal wiring. Align coupling precisely. Connect protective earth wire to motor housing. Complete motor auto-identification in servo drive and test brake operation.
Usage Notes Avoid continuous operation above rated temperature. Inspect shaft seal periodically for oil and dust ingress. Do not manually force rotation while brake is engaged. Keep terminal box tightly closed during operation.
