The Bosch Rexroth synchronous motor MPN R911299799 (MKE047B-144-KG1-AUNN) is designed for demanding industrial applications, featuring integrated overload protection and motor temperature monitoring. This motor achieves a maximum speed of 7,000 min-1 and incorporates enhanced heat dissipation through its housing and stator winding architecture. It uses electrical commutation for reliable frequent start-stop operation. Key specifications include a 0.00017 kg·m² rotor inertia, 36.3 V/min-1 voltage constant, 5 Ohm winding resistance, and 0.59 Nm/A torque constant at 20°C. The unit incorporates an electrically-released holding brake with 24V operation and 2.2 Nm brake torque. The motor has a plain shaft with frontal centering, DIN 332 compliant 'DS' thread, and shaft seal. It adheres to UL/CSA housing standards, insulation class 155 (F), and is intended for environments with potentially explosive atmospheres. Resistance to hydraulic oils and organic solvents is limited, and operation under extreme temperature fluctuations should be avoided. Connection direction is on the A-side via terminal box, and this specification refers to size 47, winding 144, with four pole pairs.
