Description
Bosch Rexroth MKD071B-061-KP0-KN
Technical Specifications MKD071 frame size; permanent magnet synchronous motor; resolver feedback; no built-in brake; 400V three-phase winding; flange mounting; IP65 protection rating; smooth output shaft.
Functional Features Compact shorter housing without brake assembly; resolver feedback withstands industrial vibration; high peak torque capacity for transient load; low rotor inertia for fast acceleration and deceleration; low cogging torque ensures smooth rotation; aluminum housing provides effective natural heat dissipation.
Application Scenarios Continuous running conveyor servo drive; printing machine roller drive; winding and unwinding equipment; rotary indexing table; machine tool auxiliary axis with external mechanical locking.
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 motor housing; laminated silicon steel stator core; rare-earth permanent magnet rotor; insulated copper stator winding; stainless steel output shaft; polyurethane shaft lip sealing ring; metal resolver feedback assembly.
Structural Characteristics Cylindrical motor body with front mounting flange; rear resolver feedback unit, no internal brake chamber; side terminal box for power and resolver signal cables; shaft outlet lip seal for environmental protection.
Working Principle Three-phase variable frequency current from servo drive excites stator winding and generates rotating magnetic field. Permanent magnet rotor rotates and outputs mechanical torque. Resolver continuously measures rotor angular position and speed, transmitting feedback data to servo drive to realize closed-loop speed and position control. No internal brake fitted, shaft free rotation when power cuts off.
Installation Requirements Fix motor flange firmly on machine structure. Use shielded power and resolver cables. Align coupling and avoid radial overloading on shaft. Complete protective earthing of motor housing. Perform motor parameter identification in matched Rexroth servo drive.
Usage Notes Add external mechanical locking device for vertical axis applications. Prevent shaft overload and mechanical impact. Check shaft seal regularly. Do not disassemble resolver assembly without professional tools.
