Schneider Electric BMH1904P31F2A Servo motor BMH 100 Nm 3000 rpm with keyway shaft content_copy

BMH servo motor from the Lexium 32 servo drive series. The BMH series of three-phase AC servo motors has a medium rotor moment of inertia and is perfectly suited for applications with high loads. Thanks to the winding technology, a very high power density is achieved in a compact design. This servo has a nominal continuous stall torque of 100 Nm and reaches a peak torque of 230 Nm. Its nominal speed is up to 2000 rpm depending on the supply voltage. This results in a voltage-dependent nominal power of up to 9.8 kW. The built-in encoder is designed as a single-turn with 128 periods/revolution (128x1024) as a SinCos Hiperface. The electrical connection is made via M40 and M23 connectors, angled by 90° and rotatable. The motor flange for fastening is 190 mm. The drive shaft has a diameter of 38 mm. The shaft end is designed as a key and complies with protection class IP65. The motor housing complies with protection class IP65. A holding brake is integrated. The servo amplifiers from the Lexium LXM32 series are recommended for operating the synchronous motor. Thanks to the Green Premium eco-label, you can receive detailed information on material content, environmental impact and circular economy that supports your sustainability goals.
